Another Question About Login Failed, But With Windows NT Integrated Security For SQL 2005
Jan 4, 2006
Hi, Happy New Year!
I have been struggling with this problem for a while with SQL 2005. I have never had such login problem with SQL 2000. Here is the scenario:
I have installed SQL2005 standard version on a XP Pro box and I am trying to access it from another XP Pro machine. I can access it using a SQL user name and password that I set up on the server, but I have not had luck with using Windows NT Integrated security. When I try to connect to it (e.g. by a UDL file), I get an error saying Login failed for user €˜HP-AMD64Guest€™ where €˜HP-AMD64€™ is the name of the PC running the SQL 2005. I can access the files on the machine without any problem. I do not understand why it uses €˜Guest€™ that is not what I use to log on my machine. Does anyone have any clue to offer me?
I am trying to connect SQL database through code but I get this error,I have spent days to solve it but unfortunately I couldn't...Here is my code in VB express(OP:windows 2000 with SP4)I am new to VB,so it makes the situation more difficult for me.
my code is:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim conn1 As SqlConnection = _
New SqlConnection("Data Source=.SQLEXPRESS;" & _
"Integrated Security=SSPI;" & _
"database=deneme3_database;")
'Open connection
conn1.Open()
MessageBox.Show("Connection succeeded.")
'Close connection
conn1.Close()
MessageBox.Show("Connection closed.")
End Sub
The error message is,it is in german but it is clear I guess:)
" Die von der Anmeldung angeforderte "deneme3_database"-Datenbank kann nicht geöffnet werden. Fehler bei der Anmeldung. Fehler bei der Anmeldung für den Benutzer 'ADPLANatalay'. "
Any idea why I cannot connect to a SQL Server database using SqlConnection and no Integrated security? I get a "Login failed for user 'XXXX'" error. The user ID and password I am using are all correct and have the required access (tested several times from different places).The connection string I am using is: "Server=XXXXX;Database=XXXXX;Trusted_Connection=fal se;User ID=XXXX;Password=XXXXX" I have also tried replacing "Server" by "Data source", "Database" by "Initial catalog", "Trusted_Connection" by "Integrated security", "User ID" by "UID" and "Password" by "PWD".Any ideas?
I got a website using .Net v2.0.xxx and SQL Server Express 2005 in a Win2003 Domain Controller machine. Both website and SQLServer is running on the same machine. Website and SQLServer are configured to accept only Integrated Windows Authentication. Domain Users group is added in SQLServer logins list and given Read and Write access to the database used by the website. Also Domain Admins groups is added and given full permission to the same database.
I thought since website will run only with login details from Active Directory, SQL Server connection is also going to be validated against the same login details. But I felt I got the whole concept wrong when I received the error mentioned in subject line.
Can anyone please explain the best way to connect to database in above-mentioned context. Please remember that I need to implement different rights on the database for 'Domain Users' and 'Domain Admins' group. If there is a better approach than using these groups, lemme know please.
Can we implement a table level (object) security on the groups of the windows NT domain using the integrated windows NT security so that one group has the permission over one table to update ,select ,delete the information and other group has permission has for some other table.
In my architecture I have a Domain Controller with Active Directory (DOMAIN_A), IIS 6.0 (WEBSERVER) and SqlServer 2000 (SQLDBSERVER).
The WEBSERVER has a .NET application with windows authentication. The .NET application interacts with the database server. I want to use Integrated Security to pass in the users login credentials to the database to run any database calls so that I can audit who is making what calls on the database.
The connection string I am using for this is as follows:
The problem arises after I login to the web application (I use the user DOMAIN_ASomeUser where SomeUser is a user who has permissions set up to make all of the database calls). After logging in however, when I go to a page that makes a database call I get the following error:
System.Data.SqlClient.SqlException: Login failed for user 'DOMAIN_AWEBSERVER$'. It seems that for some reason, .NET is not passing the login name SomeUser, but instead is passing SERVERNAME$. Would anyone pls have any ideas how I can implement this. Any guide or references would be much appreciated.
I am having a problem in applying subscription to a report.
Here is my case:
I have a datasource with 'Windows integrated security ' authentication, yes....I am using windows domain authentication, so login info is not stored in DB but its authenticated from domain. Now the report I want to use subscription on is using this DS. I read it somwehere that I can use rsconfig -e -u -p option to assign user to unattended reports.
I think, this is the unattended report. I tried with rsconfig and then clicked on 'new subscription option'...and i got error (again) saying 'Subscription can not be created because the credentials used to run the report are not stored...or if linked report.....blah blah...'
I want to use subscription to this report but with 'Windows integrated security', is there any way I can do it ?? How can I assign some user to this report without changing authentiation method and use subscription ?
Help me ...I am stuck, this is the last milestone in my project !!!
I have a set of reports that read from an Analysis Services cube. Permissions are managed at the cube level since different users should look at the same report but different data. This is why for those reports, the data source has Windows Integrated Security set.
Those same users should be able to subscribe to those reports, the problem is that for subscriptions to work, the data sources must store the credentials. This means the filtered reports are lost since the stored account will show all the reports for all users.
Is there any way of generating "filtered subscriptions"?
We have a SQL Server Reporting Services instance running SP2. I have attempted to add a domain group in a trusted domain to the server to enable regular users to access reports. I have added this group to the instance folder as a SYSTEM USER and home as BROWSER. I am allowing those settings to be inherited down through the folders (reports and data sources) to the reports. My test user in this report receives:
The permissions granted to user 'DOMAINuser' are insufficient for performing this operation. (log shows HTTP 500)
when the user attempts to use the URL to go directly to the report. If we try to navigate from HOME and walk the folders the user sees a blank HOME page.
I have used other groups with no problem.
Is there something I am missing in setting up the security environment? Any help would be greatly appreciated.
Server: Windows 2003, SQL 2005, on a domain Client: Windows 2008 Beta, not on any domain
I created an account with the same user name as the domain user on the client machine. And then I logged in as that user and went to Manage Network Password. I entered the correct domain credentials. Verified that this worked for file shares. However, SQL does not appear to be recognizing this and it tells me:
Login failed for user ''. The user is not associated with a trusted SQL Server connection.
I have verified that this domain account is working properly with SQL when the client is also on the domain.
How can I get this Windows authentication scenario to work where the client is not on the domain and the SQL server is on the domain?
We're having a bit of a problem getting Integrated Security to work with a .Net 2.0 application and SQL 2005. While we're tweaking permissions on the SQL-side, we came across an account "Application Login" and wondered what its role is. First, our problem:
Currently, the users in the AD group get a connection error. This group is defined as follows at the instance level:
role: public user mapping: to the database without any default schema securables: none status: grant and enabled
At the database security level:
general: none securables: execute on all (100+) stored procedures
And we gave them "Execute" on the database itself.
A little background: we had detached and copied this database from one server to another. So we suspect that the Application Login may have been modified/corrupted, even though it appears to be identical between the original and the copied databases. So we redefined it on the copied DB to match the original. Another group, which is defined as dbo on the database, has no problem at all connecting and running the application.
The Application Login has Execute permissions on all stored procedures and Delete, Insert, Select, Update, and View Definition on the ChangeLog table. It also has db_DataReader, db_DataWriter, and db_ddlAdmin roles associated with it.
Is there another SQL login required for initial connection to the database even though Integrated Security=SSPI is used in the connection string?
Does anyone see where we may be missing a security setting for the non-dbo user group to connect to the database?
Thanks very much for any suggestions, ideas .... Cheers, Tess
Hi , I am trying to connect to MS Sql server 2000 from Java (1.4.2 /1.5 ). I installed my Sql Server(8.00.382) from the one supplied withVS.NET 2001. When I installed it on my laptop it did not ask me for auser name and password. After install when I re-started my machine Isee the server started up with a green light. Now when I connect to theserver from VS.NET it works fine. This is because VS uses windowsintegrated security. I now need to connect using Java , so I downloadedthe microsoft drivers for SQL2000-JDBC sp3 from the microsoft site. Iadded the jar files to my Java project classpath. I manage to registerthe driver in java :Class dbClass = ClassLoader.getSystemClassLoader().loadClass("com.microsoft.jdbc.sqlserver.SQLServerDriver");DriverManager.registerDriver((Driver) dbClass.newInstance() );Connection conn =DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433;_integrated security=SSPI");but cannot seem to get a connection as it gives an SQLException sayingthat it is unable to connect:java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Errorestablishing socket.I cant seem to figure it out.Can some one help ??I am a newbie to sqlserver so couldnt quite figure out how to changeadmin password or create a new user with the tools provided with thisversion of sql (SQL Server Desktop Engine).Any help will be appreciated.Ebby
I am trying to connect to an SQL database with a Java program compiled in NetBeans IDE. I have copied the proper .dll in the auth folder to the same folder as the .jar file required. I have tried a lot of things for a lot of hours, and am still coming up with the message "Driver is not configured for integrated security and "could not load the xxxxx.dll
Has anyone come up with a solution or a workaround to this problem. Please help. I have read the documentation until I am blue in the face. Please only respond if you have a 64 bit machine.
I 'm a newbie to SQL Server, been using Access as a database for my web app. and have decided I need the power of SQL Server. Using VWD Express, I am able to generate a SQL database with my tables and stored procedures quite easily as well as access the database from my asp.net code. This works fine on my devlopment machine. But now I want to deploy on my remote server and the webhost says they can attach my SQL database but they need my SQL login info. So I have a couple of questions: 1. Does the SQL database I create in VWD express only work in Integrated Security mode or can I assign a username & password to the .mdf file so I can upload to my remote host to work in a shared SQL environment? 2. Or am I confused and the .mdf file is just a data file which can be attached to any SQL account and the SQL login info only pertains to the instance of SQL Server that I'm trying to connect to? 3. My web host mainly uses SQL Server 2000. Will a simple database created in SQL Server 2005 Express work on an instance of SQL Server 2000? If I can just figure these simple items out, I will be ecstatic!
We are having some commercial applications that are running on sql servers at different sites, all with sql security. The software vendor wants to copy data into staging tables on our BI server. But our BI server only support Integrated security.
But how can i say, in the definition of a linked server (at the remote machines) to swicth security system ?
If it is possible i could enter a fixed domain-account in that users fields, but i suppose that this field was intended for SqlServer security.
hi i have created a username and a password in sqlserver 2000 from logins in Enterprise manager and i permit him to the database i need to connect to .. and i check all server roles for that user and i make sqlserver authentication for him with a password and then i goto the udl file to connect to that database using that user it fails !! and says
"login failed for that user 'myusername' reason not associated with a trusted sqlserver connection"
while i use NT integrated security it works well so how can i connect to sqlserver using a username and a password
I know from searching this forum that there have been many variations of the issue I'm currently suffering, but I haven't found anything quite like mine or a solution to solve it. The issue I'm running into is that I am unable to log on to Reporting Services using Management Studio or the web interface when Windows Integrated Security is enabled. I have full functionality using basic security, but the risks involved make it impossible to deploy basic authentication out into production. The error I'm receiving in Management Studio is The request failed with HTTP status 401: Unauthorized. (Microsoft.SqlServer.Management.UI.RSClient). I recieve the same error when I try the web interface.
I've looked the most recent logfile in WindowsSystem32LogFilesW3SVC1 and these entries match up to the time I attempted my authentication.

I tried to highlight one of each of the HTTP errors I am getting. 401.2 and 401.1 are the ones I kind of expected, but have no idea why I'm getting them. The 500 0 error is a bit troubling, because unless I'm mistaken thats a server side error.
Here's my current setup. As far as I can tell, I've done everything to set up correctly for Windows Integerated security.
My Specs The server machine running all SQL 2005 services. It resides in a domain. All Clients are in the same domain.
Intel Dual Processor 3.20 gig Xenon
Windows Server 2003 w/ SP2
Microsoft Sql Server 2005 w/ SP2 Reporting Services Setup The virtual directories Reports and ReportServer are set to Windows Integrated Security with Anonymous Access disabled. All other checkboxes in Directory Security are unchecked. For permissions in Reports, I have:
Administrators (servernameAdministrators) - Full Control
ASP.NET Machine Account - Modify, Read & Execute, List Folder Contents, Read, Write
Domain Users - Read & Execute, List Folder Contents, Read
SQLServer2005ReportingServices]WebServiceUsers$... - Read & Execute, List Folder Contents, Read
SQLServer2005ReportServerUsers$... - Read & Execute, List Folder Contents, Read
SYSTEM - Full Control
Users (CompNameUsers) - Read & Execute, List Folder Contents, Read In ReportServer I have the same permissions except Authenticated Users is absent.
At one point, I even added the account Everybody and gave it full control, and I still recieved a HTTP 401 error. Any help at what I might be missing would be a godsend.
If I am posting to the wrong forum, please point me in the right direction. We have upgraded to SQL Server 2005 and Window 2003 from SQL Server 2000 and Windows 2000, and have been having all kinds of problems with security of our web applications. We have been forced to put the system account of the web server as a user in the database in order for the web applications to work. We have lost the ability to control security at the user/role level. Is this the way security is going to work in Windows 2003/SQL Server 2005? How do I use integrated security so that I can secure web pages and database objects? Thanks
Hello, I have a sql 2005 server, and I am a developer, with the database on my own machine. It alwayws works for me but after some minutes the other developer cant work in the application
He got this error
Login failed for user ''. The user is not associated with a trusted SQL Server connection. [CLIENT: 192.168.1.140]
and When I see the log event after that error, it comes with another error.
SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed. [CLIENT: 192.168.1.140]
He has IIS5 and me too.
I created a user on the domain called ASPSYS with password, then in the IIS on anonymous authentication I put that user with that password, and it works, on both machines.
I go to the profiler, and I see that when he browses a page, the database is accesed with user ASPSYS, but when I browse a page, the database is accesed with user SElevalencia.
Thats strange.
The only way that the other developer can work again on the project is to restart the whole machine. He has windows xp profession, I have windows 2000.

Troubleshooting done: - Recreated the windows login in sql server. Doesn't work. - ran sp_valdidatelogins. it doesn't return any rows. - I belong to sysadmin role and when I say, getting below error message.
xp_logininfo 'domainloginname' /* Msg 15404, Level 16, State 19, Procedure xp_logininfo, Line 64 Could not obtain information about Windows NT group/user 'domainloginname', error code 0x5. */
We tried dropping this account and re-creating the windows account with same permissions but still result is same.It throws same error message. Login failure message !!!
In my DB (SQL 2012) one windows authentication is created automatically and a schema is created exactly automatically that this user is owner of this schema. (e.g the user is domainx and schema exactly domainx).
I created a DDL Trigger on my DB to find out who and how it is created , but I didn't get any useful information.
I change the owner of schema that I can delete the schema and after that delete the user, and sometimes because the user is owner of a service , I have to alter the owner of the service to DBO and delete the user , but again and again exactly this user and schema (e.g domaninx ) are created as soon as I delete it.
I have read these topics : [URL] .... and [URL] .... but can't solve my problem.
I have a test environment set up at home with a small windows server 2003 Active Directory domain. I created a windows security group on the dc and added myself and another user to the group. I then use this group as a login for SQL Server and add the login to the sysadmin server role. This works exactly as I would expect on the Windows Server computer (which is also the Domain Controller) regardless of which computer I use to connect to this Windows Server computer. However, when I set up the exact same login on the local sql server instance of my client laptop running windows xp pro, the I get an error message (Login failed for user MYDOMAINdgolds...) when I attempt to connect to the local instance of SQL server, even though I am able to connect to the instance on the domain controller with no problems using this same client laptop under the same user account. The only way I am able to connect locally on the laptop under this account (which does not have local admin privileges on any box, for testing purposes) is to add the user account separately as a login, rather than as part of a group. I'm curious as to why being a member of a security group that is part of the sysadmin server role does not allow me to connect to the local instance of SQL Server on this client laptop. The windows server computer is running SQL2k5 Enterprise, and the client laptop is running SQL2k5 developer. Any insight into this would be appreciated.
I'm building a Windows Service which keeps getting denied access to SQL Server 2k. The Service operates as a System User rather than an individual user profile.
I've tried Trusted_Connection=yes and Integrated Security=SSPI but these are both denied.
Any ideas what the connection string to connect to SQL Server 2k from a Wndows Service is?
We have a Web application that requires user authentication. We have a Login Page for user's to login and be authenticated. We also manage the user accounts using SQL Server Membership Provider. We created aLogin user in SQL Server and used this user's privileges to connect to SQL Server in our website's connection strings. Example, in our Web.config file, the connection string is:
<connectionStrings> Â <addname="MyConnectionString"connectionString="Server=MYSERVERNAMESQLSERVER2012;Initial Catalog=MyDatabase;User Id=TUser;Password=MyPassword"providerName="System.Data.SqlClient"/> </connectionStrings>
The problem now is when a user logs in, it's throwing an error that TUser's password has already expired. We did not enforce the password policy and expiration date for this user. So, I'm wondering why it's giving me this error.
Deleting a Login from a server instance and adding it back did not show that the login was still mapped to databases. In SQL Server 2008, adding a Windows Login did not permit access to end user databases until the Windows Login was mapped to various databases. In SQL Server 2012, once a Windows Login is added to SQL Server Security, it may access ANY end user databaseWe use the following to circumvent this problem, Windows Login by Windows Login: DENY VIEW ANY DATABASE TO [TESTTest1]
I'm working on an ASP.NET project, and we're attempting to switch from SQL Server authentication to Windows authentication to connect to the database. It works fine locally when I debug in Visual Studio, but when it hits the web server, I get the error: "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection." IIS has anonymous access disabled, and Integrated Windows Authentication is checked. The web.config file has: <authentication mode="Windows"/><identity impersonate="true"/> The database I'm attempting to access is on a different machine than IIS, and the connection string doesn't contain a username or password, and has "Trusted_Connection=Yes", and "Integrated Security=SSPI". From what I've been able to find online, I'm guessing the problem is due to IIS and SQL Server residing on different machines, but I'm not sure how to fix it. Any ideas?
Any way to find out who's causing "Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection." error in SQL Server error logs?
