SQL Security :: Windows Authentication Not Working With IP
Sep 17, 2015
This is for SQL Server 2005
When logged onto a server and connecting using windows authentication (either by server name or localhost) I am getting in fine, but when I connect using the IP I get the following error.
I can log in using SQL Server authentication with the IP.
I am trying to access the SQL server using windows authentication but its not working. But others can work on their windows authentication for the same server. Anything needs to be done from my end. Please explain.
We're using windows server 2012 R2 and sql server 2014 standard with mixed mode authentications. When we connect to other windows server using windows authentication and hit the following error:"the target principal name is incorrect cannot generate sspi context"..is the above err related to mixed mode authentications at installation?
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 two SQL Server machines - RPTPROD and DATAPROD.
I wanted to create a linked server from RPTPROD pointing to DATAPROD using Windows Authentication. When I tried to create this linked server, I keep getting this error
"Login failed for user 'NT AUTHORITYANNOYMOUS LOGON' (Microsoft SQL Server,Error: 18456)".
On the "Security" page, I chose "Be made using the login's current security context". I'm sysadmin on both SQL Server machines.
This morning I attempted to connect to my local copy of SQL Server (2012) (Win 7) using Windows Authentication. I was unable to do so and per the error log it was due to error 18456 (invalid credentials).
Yesterday I changed my windows password. Is it possible for this to be the cause?
FYI, following is from the error logs:
2015-04-27 10:10:32.98 Backup BACKUP DATABASE successfully processed 0 pages in 0.451 seconds (0.000 MB/sec).2015-04-28 00:00:41.90 spid18s This instance of SQL Server has been using a process ID of 2096 since 4/21/2015 9:08:05 AM (local) 4/21/2015 1:08:05 PM (UTC).

This is an informational message only. No user action is required.
The logs showed the error occurred yesterday (4/28) which is about when I changed my password. The 17:09 log (last one) is when I shut down my computer. Note that I was logged into SQL Server when I changed my Windows password and worked with it several times through out the day.
Also, per the configuration manager SQL Server (MSSQLSERVER) (and all other services) is stopped and I was unable to start it ("The request failed or the service did not respond in a timely fashion).
Hi there,I have installed MS SQL Server 2005 on my machine with windows authentication. But now I want to switch the authentication mode to SQL Authentication. I am unable to switch, I can’t find the proper way to do so here in 2005.Could any one help me in doing this?Thank you,-Ahsan
(Using win2k, sqlserver2k, framework 1.1) I have an fairly data-heavy application that uses Windows authentication (Trusted connection/aspnet account) to connect to Sql Server. The site uses IIS basic authentication.
On the dev server everything works fine but when I move to the live server things get strange and it starts to crawl along. (Pages load OK but then it just crawls as it loads the datagrids etc. Sometimes it brings back incomplete/incorrect data )
BUT When I use Sql Authentication to connect to Sql Server and there is no problem at all!
Ok, there is something obviously wrong with the live server (which is identical setup to dev)but I dont know where to start.
I've got two applications which both have a database on my MS SQL 2000 server. The problem is, one application must use Windows Integrated Authentication (which it is currently using and cannot be changed) whilst the other application which I'm trying to configure must use a SQL password.
Since the server has already been configured to use Windows Integrated Authentication for the existing database and application, how do I configure the other database to use the SQL password?
My work is using a shared application which accesses a MSSQL 2000 database. To access the application, the folder on the Windows 2003 Server is shared and users can access the folder through a shared drive.
For the application to access the database, it uses an ODBC connection to the MSSQL server which originally used the SA password.
We have recently switched to using Windows Integrated Authentication because we believe it offers a higher level of security. However the only way in which we have been able to enable this is to add the windows users to the SQL server.
The problem with this is that the application sets permissions for individual users on what records they can see within the database. We have found that by adding the windows users to the SQL Server, they can bypass the permissions the set by the application by simply using any application that can use an ODBC connection, such as Enterprise Manager, and see all the database.
One way around this would be to set up domains of users with access privileges to the tables which reflect the permissions set by the application, and configuring a view of the data so they may only see the records that they have permissions to. However to do this would require a high administrative cost to ensure that changes made in the application are reflected in the privileges of the SQL server.
Instead, is there a way the SQL server can authenticate that the ODBC connection is coming from the correct application using Windows Integrated Authentication?
This would allow the applcation to determine security, and stop users from connecting to the SQL server using other applications.
Alternatively, can the SQL server, using Windows Integrated Authentication, also ask the application to supply a username and password?
Any help with this matter would be greatly appreciated.
I just upgraded from Windows XP Pro to Windows Vista Bussiness and tried to reinstall SQL Server 2005 Developers Edition. After the installation i downloaded (using microsoft windows update) and installed all the service packs for sql and vista available.
My problem is when i open sql server management studio and try to connect to my default instance using windows authentication and database engine, an 18456 error occurs.
I enabled all the protocols and all the ports I disabled windows firewall and antivirus (eset nod32) I installed all service packs available I have also installed Visual Studio 2005 without installing sqlexpress
But nothing happens!
Please i am very desperate, any information will be gratefully accepted.
This is my installation Information

Say, I have configured my SQL to use Mixed Authentication. Now, I have a applicaiton which uses my SQL Server. The application just creates a database in SQL Server and uses the database to store its information.
This application also has a SYSTEM DSN under ODBC through which it accesses the database. For the application to access this database, should I only use SA (as my SQL instance is configured to use Mixed Authentication) or can I use Windows Authentcation too...
If I should only use SA, do we have a documentation which talks about this.
For using different services of SQL SERVER 2005 which is better... Windows Authentication or SQL Server Authentication? what are the advantages and disadvantages of both?
I wonder if it is possible to set forms authentication for report manager but leave report server "as it is". I need to authenticate users from external LDAP and can't use windows authentication for report manager, but I would also like to leave report server open for anonymous users. In that way authenticated administrators could create reports which anonymous users could read.
I tested the Security Extension Sample and got it working when I rewrote the authentication part with my own LDAP authentication.
If I have understood correctly, the report manager is just application inside report server so is it possible to use forms authentication with one application but still leave the report server with Windows authentication?
Is there any possibility to schedule SQL job execution as Windows Security Group? I need to run powershell script through SQL job with one of this group member's permissions.
I am in the process of rolling out a sql server 2005 enterprise install and had a question regarding authentication. We will be providing sql hosting for a number of groups on our campus, many who are not using our campus-wide active directory, though they all have an AD account.
Windows authentication via the management studio appears to use your AD authentication tokens and will not allow them to enter a username/password combo. Is there any way to configure this?
I would like to use our campus AD for obvious reasons but if there is a requirement for passing tokens this isn't going to work right? It's also going to make database mirroring more of a challenge.
Hey there, I have a table [user] in a SQLExpress database [Database.mdf] in the App_Data folder. There are two columns. [userId] and [password]. I want to authenticate the user who wants to log in through a Login control. the user should have his userId and password in the [user] table. I digged and made my code. but it doesn't work it keeps giving me that the user is not authenticated. i guess it has no errors. please tell me if you find the error. here is the code: 1 protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) 2 { 3 SqlConnection conExpress = new SqlConnection("Data Source=.\SQLEXPRESS;Initial Catalog=Database;Integrated Security=True;User Instance=False"); //Create the server connection 4 5 try 6 { 7 string id_user = Login1.UserName.Trim(); //Get the username from the control 8 string pass_user = Login1.Password; //get the Password from the control 9 10 //These are a sql and connection Examples 11 string sql = "SELECT userId, password FROM user WHERE userId = @param_Id AND password = @param_Password"; 12 SqlCommand comSQL = new SqlCommand(sql, conExpress); //Create the sql command using sql string and sql connection 13 14 //Add the sql parameters 15 comSQL.Parameters.AddWithValue("@param_Id", id_user); //New on VS 2.0 16 comSQL.Parameters.AddWithValue("@param_Password", pass_user); 17 18 string cod_user = ""; 19 string name_user = ""; 20 21 //Open database connection 22 conExpress.Open(); 23 SqlDataReader dr = comSQL.ExecuteReader(); 24 while (dr.Read()) 25 { 26 cod_user = dr.GetValue(0).ToString(); //The coduser is unique onto database table 27 name_user = dr.GetValue(1).ToString(); 28 } 29 conExpress.Close();//Close Database Connection 30 if (cod_user != "") //The user exist onto database 31 { 32 //Create the session vars 33 Session["coduser"] = cod_user; 34 Session["nameuser"] = name_user; 35 e.Authenticated = true; //Grant the access, Goes to DestinationPageUrl 36 } 37 } 38 catch(Exception)//On Login Error 39 { 40 e.Authenticated = false;//Confirm that you are out 41 conExpress.Close();//On any error case, close the database connection 42 } 43 }
I am looking for a way to log all security related events for SQL in Windows Security Log. I am trying to use SCOM for monitoring SQL and I am looking at ways to generate alerts in my SCOM Console for specific events in SQL e.g. A table is deleted, user is modified, deleted, etc. Is this possible and if yes how do I achieve the same?
I have setup ODBC to connect to a SQL Server 200 database (evaluation version) so I can link tables into an Access database. In the ODBC setup, I selected SQL Server Authentication versus Windows Authentication. However, when I link a table into Access it still uses Windows Authentication first.
I found an article here that discusses the issue: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q279526
It suggested that I run an MDAC update to version 2.6. So I did that and I still have the same problem.
I tried to link a table through some code in Access by changing the connect string to "Trusted_Connection=No" but it still linked up with "Trusted_Connection=Yes".
My SQLExpress seems to be set for windows authentication and not sql server authentication ... I am not quite sure why it is set to windows authentication - I installed this with Visual Studio 2005 and it just seemed to be set that way.Am I able to change this - if I choose sql authentication when connecting I get an errorIf someone could answer this point I would be most grateful !!Patrick
In an effort to eliminate the need to code accounts and passwords into the VB Com calling stored procedures, I would like to use Windows Authentication. I have setup the account that the com is running under to have access to the database. How does this change my connection string. Do I just drop the account and password parameters or do I need to let it know somehow that I want to use Windows Authentication?
I'm having problems with windows authentication. I'm new to using using Microsoft SQL Server. I just migrated from powerbuilder 8 to powerbuilder 10. I'm using OLE DB and can't get the windows authentication to work within the application. Can anyone help....
Hi, I am wondering that do we need to create the separate login at SQL SERVER (server) for all the user using the application for the windows authentication?
How do the windows authentication works? I have a apllication and SQL SERVER (SERVER) running on the same machine. Any user from the same domain can access the application. Application is interacting with the DB through Windows Authentication. Now my question is whether do we need to authenticate each user from the domain at the DB level. That is to craete the login id for all the user for windows authentication.
I remove the windows authentication from enterprise manager. and Now i want to re-assign the the windows authentication . so can i do it from query analyzer.
Hi all,You're all stars, really helpful. Maybe one day i can be :)My question is regarding the authentication in Windows SQL Server 2005.We have setup a sa account. We purchase software from a third partythat runs on it. Before their software logs on the sql server as sa,and does its own access control, windows autentication takes over. Itslogs users on correctly i guess, using a more secure link via thedomain. However, I am probably blind, but where can we assign rights toeach domain user? I.e. stop XXY dropping tables, but allow ABC to droptables?I had a brief look through but could not find anything that stood out,in the SQL Manager.ThanksDavidP.S This is SQL Server 2005 Workgroup edition running on a 2003 windowsdomain server. Alongside a SQL 2000 server, which is running fine usingsa accounts.For those in the same timezones as me... have a good evening.
Hi! Happy New Year!I'm having windows authetication connection problem. Although I cansee all the servers by using SQL Server authentication conncection, Ican see only some of the SQL family servers by using windowsauthentication connection. I checked the servers' properties of that Ican and can't see, but couldn't find any difference. Can someone giveme a direction that will enable me to debugg?If the servers are not in the same domain, how can I see them (windowsauthentication) from the same PC (client)?For some SQL server I even can not login via windows authentication atterminal server. Is any specific setup I should do at server?Thanks!Saiyou
Hello,We have a SQL 2000 installation (running on NT4 SP6a) with a databaseaccessed by a client application. Currently the application logs into thedatabase using a the SA account. I'd like to move the client access over toWindow Authentication. Each user has their own NT account. What steps do Ineed to take to achieve this?Any help would be greatly appreciated.James G.
