SQL Security :: Login Failures For Windows Accounts
Aug 12, 2015
We are seeing login failures for windows accounts. Below is the error message.
Description:Â In our env most logins are windows accounts. Initially we thought it is an UAC issue and we tried to launch the SSMS using "Run as Administrator". However, we are seeing login failures.
Enviroment:
Microsoft SQL Server 2014 - 12.0.2402.0 (X64)
RTM Enterprise Edition (HyperVisor)
Error Message in Error Log :
2015-08-10 22:36:45.290 Logon       Error: 18456, Severity: 14, State: 11.

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 !!!
Hello, I'm having a problem using Windows Accounts to login to a SQL 2005 Server. Here is my setup. The SQL server and web server are separate machines. I'm also not developing directly on the web server. SQL Server - Windows 2003 Server- SQL 2005- Set to use SQL and Windows AuthenticationWeb Server- Windows 2003 Server- IIS 6.0 - Anonymous Authentication is disabled - Integrated Windows Authentication is enabledApplication web.config: <?xml version="1.0"?> <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"><appSettings> <add key="ETR_Environment" value="Dev"/></appSettings> <connectionStrings> <add connectionString="Data Source=sql-dev-server, 1179;Initial Catalog=ENV_ETR;Integrated Security=SSPI;" name="ETR_Dev"/> <add connectionString="" name="ETR_Prod"/></connectionStrings> <system.web> <compilation debug="true" strict="false" explicit="true"/> <pages> <namespaces> <clear/> <add namespace="System"/> <add namespace="System.Collections"/> <add namespace="System.Collections.Specialized"/> <add namespace="System.Configuration"/> <add namespace="System.Text"/> <add namespace="System.Text.RegularExpressions"/> <add namespace="System.Web"/> <add namespace="System.Web.Caching"/> <add namespace="System.Web.SessionState"/> <add namespace="System.Web.Security"/> <add namespace="System.Web.Profile"/> <add namespace="System.Web.UI"/> <add namespace="System.Web.UI.WebControls"/> <add namespace="System.Web.UI.WebControls.WebParts"/> <add namespace="System.Web.UI.HtmlControls"/> </namespaces> </pages> <authentication mode="Windows"></authentication> <customErrors mode="Off"></customErrors> <authorization> <allow users="XXXWilliam.Klein"/> <deny users="*"/> </authorization></system.web></configuration> The reason why I want to use the windows login to connect to the database is the application needs to keep track of who did what when entering and updating data but still keep them using there windows login accounts. So using a generic account will not work. What keeps happening is I keep getting this error: Login failed for user 'NT AUTHORITYANONYMOUS LOGON'. When trying to connect the database. I've tried this on two web servers on another I get something slightly different: Login failed for user 'XXXWeb-Server$'. Anybody able to give me any suggestions on how to fix this?
I am currently hardening our SQL 2012 (with AlwaysOn Availability Groups) environment. Both the SQL service and agent account are using service accounts (only domain user). SQL browser service is disabled. Permissions to all roles are handled by using domain groups.
Currently a lot of (default) NT Service accounts are listed (some with sysadmin privileges). Are there accounts that can be removed?
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 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'. "
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?
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 could really use some assistance. I have been researching this problem for over a month now and I have not made any headway or progress.
I am running SQL Server 2000 on Windows 2000 Server. Hardware is Dual Xeon 2.4/400 Procs, 2GB ram and 1 Raid10 Array with 4x 36 GB 10K RPM drives.
The server has about 50 dbs on it. All are primarly used in conjuction with some web application or site. On average the server sees about 270ish connections/sessions.
About 1 - 2 months ago, we started seeing random login failures. We have no explanation for these failures. Our coldfusion code gives us detailed logging information regarding the exact statement that was being executed when the login failed. We try to reproduce the failed login, we cannot. There are no misspelling, code inconsitencies in this regards because the logins are set in the data source which verify.
We are using per-processor licensing, so unless there is a hidden limit we are hitting or MS is lying about per-processor licensing having unlimmited connections, that is not the issue. Also, I've ruled out some kind of network issue because if that were the case, the login would have timed out, as opposed to failing. I've been running a trace and viewing the failed logins.
Sorry if this is a real simple question, but I just had a SQL 6.5 server dropped in my lap. I need to transfer all the data to a new box, which I did using the Tools mneu (Database/Object Transfer) in Enterprise Manager. I checked the databases after the transfer and all the data seems to be there, including the logins. However, if I try to connect the database, all logins fail.
Connection failed. SQL State '28000' SQL Server Error 4002 [Microsoft][ODBC SQL Server Driver][SQL Server] Login failed
Does any body know how to fix this easily without resetting every single user id?
If we have a "pool" SQL login, a one that uses SQL Server authentication, and this login is used by different domain account to access SQL Server, is there a way to audit which domain account used that "pool" login to do something on a object in SQL Server? I have to keep this way of accessing SQL Server, so how to create a login for every domain account accesses SQL Server
We are about to change the sa password, currently all packages and jobs rely on this account. I imagine there is probably a better architecture that we could employ to ease this process. Any suggestions recommendations?
Also any caveats I should be aware of regarding places to look that might currently rely on the sa account so that we do not need to worry about existing processes from breaking?
I think we are going to create an NT account for DTS Packages and possibly use the same account for any DTSRun jobs, does this make sense? Or is there anything to gain by having these as separate accounts? Also should this be the same account used to run the MSSQLServer process?
I tried doing a search for this information here, thinking it was already covered, but could not find anything that informative, any resources that you could point me to would be appreciated, I will look on BOL as well as MSFT to see what I can dig up.
I'm trying to harden our SQL Server environment to improve overall security of our systems. I would like to check what specific permissions are granted to SQL Server, SQL Server Agent and SQL Server Integration Services account. I've tried with the "sc qprivs <service_name> " command, but it returns an empty privilege list. Is there a way to retrieve the permissions using a cmd or powershell command?
I have a SQL2005 in a cluster environment, for some reason the only way that user accounts can login to either the database or SSMS is to grant them the SysAdmin role. This access is a little to high for my liking and am wondering if anyone else has come across this before.
I am no DBA, but this is my task.I have an SQL Server 2000 Database that has an "SQL Account" that hasexecute permission on all Stored procedures. it is what was used bythe company. This one account is used by "all workstations".I want to fix this and use Windows Accounts, and get rid of that SQLAccount. How do I go about adding that Windows Account permission toall the Stored Procedures?What I want to do is to just add several windows account then go aboutremoving the permission where necessary on an account by accountbasis.Any suggestions would be greatly appreciated!
In a previous thread, I got some help from you all in figuring out how to deploy a per-machine desktop application and database so that it would be available to all Windows accounts on the machine. Basically the advice was to create an SQL user for the database with the BUILTINUsers login which had the necessary privileges for connection.I have tried this approach, but I am still having problems with connections for unpriveleged users. I have given the database user the role of db_Owner as well as other roles, but it seems to make little difference. I have been trying the deployment on several machines running XP, and I get several different responses. But primarily I get the "CREATE DATABASE permission denied in database 'master'" error. All of these computers seem to have the same database user level permissions, but obviously there must be differences somewhere. That worries me from a deployment standpoint.
I don't want to make any changes at the server level login properties for Builtinusers, but I have experimented with changing these, and I've found that giving sysadmin privileges to BuiltinUsers works great. But I doubt that anybody would be very happy with that solution.
I'm confused about the "Create Database" message, because I'm not explicitly creating any database at application startup time. It also seems like this might be an attachment problem, but I'm not sure about anything. Is there really an attachment and detachment of the Express database every time the application is run?
So my bottom line questions are: Which database level privileges do I need to give to my SQL user with BuiltinUsers login so that any Windows account can connect and write to the database? Can I accomplish this goal without changing any server level privileges for the BuiltinUsers login.
I am attempting to use Visual Web Developer Express with a connection to a SQL Express db from a non-admin account on my XP Pro SP2 machine.
I can do everything in the app under an admin login, but can't seem to configure the db to allow the non-admin account access to the db. I've tried tweaking WMI, using Network Service, Local Service, and Local System with NT AUTHORITY, individual logins, and group permissions, but I'm stuck.
Hi Folks SQL2k on NT4 Domain I have a UserDB on SvrA - Access to UserDB is Via a DomainGroup and is assigned db_owner role UserDB Executes a local SP which in turn Executes a remote SP on SvrB via a Linked Server The Linked Server Login Security is via mapping to a remote account which has db_owner on the remote DB. I would like to. a) stop ALL users on SvrA from being able to use this linked serverb) tightly restrict permissions of the remote account to the remote db Is it possible to MAP above local server login to remote server login as the local login is via a domain group. I cannot significantly alter UserDB current Login Security I'm also worried that another system/db is utilizing this Link (legally) but I'm not allowed on the production box to monitor it (Hhrummphh - but unfortunately I have the job of providing scripts to tighten security :rolleyes: - hence the prefference for mapping local to remote users I'm sorry I'm not well versed in SQL Security & this is only a central part of my bigger security job(involving horrible RPC's, dynamic SQL, heteregeounous joins, double hops, delegation etc) Any help appreciated GW
I'm attempting to write a script that I can execute accross 30 servers that will create a domain login and subsequently grant access to said account on all databases per server. The only problem that I'm running into is trying to dymanically create the login. Example source is below.
declare @sql varchar(1000)
declare @loginname varchar(50)
select @loginname = 'DOMAINaccountname'
set @sql = 'if not exists (select * from master.dbo.syslogins where name = N' + char(39) + 'DOMAINaccountname' + char(39) + ')' + char(10) + char(13)
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.Â
I have a server that has 20 databases . I have tested with few users with different level of access and all of them were able to connect to the server and also see, select, update , delete from a particular database which is kind of weird because they do not have a user login associated or mapped to that database. I checked and no user is part of any group in AD that would give them permission to connect . I need a query that would find the permission path of a user. I already queried with xp_logininfo but I am not getting any thing.
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 cannot get a consistent answer as to how many domain accounts would be suggested in a SQL Server 2014 installation. Previously the recommendation was a separate account for each service to provide isolation and minimum permissions for each account. It seems from what I've read that a single domain account would have something added to make it unique from SQL Server's perspective. Several still advocate multiple accounts. I don't know if they are doing so because that's the way it's always been done or if there is still some compelling reason to do so. I don't want to create unnecessary accounts simply because something is "ideal."
I am trying to revert back to Windows 7 after upgrading to Windows 10, however it will not let me and the following message occurs: "Remove new accounts.Before you can go back to a previous version of Windows, you'll need to remove any user accounts you added after the most recent upgrade. The accounts need to be completely removed, including their profiles.You created one account (NT SERVICEMSSQLSERVER) Go to Settings> Accounts> Other users to remove these accounts and then try again".However I did not create any new users and there are no other users listed in the Accounts section.
I have 2 networked PC's both running vista ultimate
1st is Laptop and is running its own SQL Server at laptoplaptopSQL 2nd is Desktop and is running its own SQL Server at desktopdesktopSQL
Now both machines have seperate windows login accounts.
When I go SQL Server management studio I go to browse and each machine can see the other machines SQL Server, but when I go to login I get SQL Login falied for users" The user is not associaed with a trusted SQL server connection".
So I then go to logins new login and try to add my other pc's user account. The problem I see is that when I go to search and then location it only shows its own PC's location and not the location of my other networked pc? So if I am on Desktop and in my theory want to add laptopuser to the desktop SQL Server logins I get:
"create failed for login laptopuser
An exception occurred while executing Transact SQL statement laptopuser is not a valid windows NT name. give the complete name
Oracle and Teradata are able to capture the windows/client login that connects to their database with a functionnal ID.I've searched around and I don't think MS SQL can do this...I administer SQL 2014 server and also SAS Enterprise guide product. I've created sql server logins for several teams so everyone shares the same sql server login which is used to bind the SAS library to my SQL server database.
However, when looking at activity monitor, I can't drill down to which user is executing a particular query. I only see the SQL login which is share amongs 200 other folks.On the other hand, when they connect from SAS to Oracle or Teradata, I can see the shared login + additionally their windows NT login used to connect to SAS which is awesome....they can't fool me by using a shared/funcionnal ID....i still see who's using that ID...
What's the better security to use? Currently I'm always registering using the Windows authentication. When I'm trying to register using SQL authentication I always get "Login failed for user 'sa'" error....
