The XYZ group has around 10 users in there who are successfully able to access the SQL Server database. I recently added a new user to this group (at AD level), but this person is not able to access SQL Server (through Mgmt Studio) and he's getting the error below Login failed for user. Reason: http://dba.stackexchange.com/questions/37564/login-failed-for-user-error-18456-severity-14-state-11 Token-based server access validation failed with an infrastructure error. Check for previous errors. Error: 18456, Severity: 14, State: 11. I have already verified AD permissions are setup properly, user has restarted his machine, he is not part of any group that has DENY access and the SQL Server XYZ group has been removed and readded to the SQL Server instance in Mgmt Studio and server has been restarted. Any ideas on how to proceed further?

Can you have the new user try from another computer and see if that's the issue? Wondering if it's an AD setup issue, since your other users are working. –Jason Whitish Mar 25 '13 at 22:23 sqlblogcasts.com/blogs/simons/archive/2011/02/01/… –Aaron Bertrand♦ Mar 25 '13 at 22:26 Has the user logged off and logged on since the group assignment? If not, the user needs to do that for the group assignment to take effect. See my answer here. –Jon Seigel Mar 26 '13 at 13:26 I had the user restart his laptop and even tried accessing from another computer but no luck.. –Amam Mar 29 '13 at 14:30 Checkout these 2 threads would be help you: social.msdn.microsoft.com/Forums/en-US

See below example. This http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx usually means that your connection request was successfully received by the server name you specified but the server is not able to grant you access for a number of reasons and throws error: 18456. This eventID sometimes error 18456 provides also state 1 which actually isn’t that useful as due to security reasons any error is converted to state 1 unless you can check logging on the server. Microsoft does not provide very useful message boxes so below are some explanations why you get the error. Want to easily improve your SQL Server Skills? Before you dive in If you are NOT a DBA (Server Administrator) then read this. We had a login failed for number of online private chats using our website chat feature and we have identified there are a number of situations where you cannot do anything about it! We are aware some of you might be very new to this so I will provide you with simple list of questions or steps to check if you are in the 'cannot do anything about it' group. Before you start "fixing" it please go through the list below: Are you the person managing the server or the person who installed sql server (e.g. personal pc/laptop)? If no or you don't know, then there is a high chance you don't have permissions to fix it. What does it mean? It means you can only do what you are in control of (typing username, password) or trying steps that don't involve changing server configuration. If nothing works contact your server administrator (DBA). Are you connecting from an app (Visual Studio etc.) and not SSMS? If yes then try to connect from SSMS if it works then problem might be in the app. If no then is there any user account that works? Yes? Then username may not exist or might be mispelled. Password might be incorrect. Account may be disabled. No? Try next point. Using SQL Sever Management Studio (SSMS), Are you able to connect us

Troubleshooting Error 18456 I think we've all dealt with error 18456, whether it be an application unable to access SQL Server, credentials changing over time, or a user who can't type a password correctly. The trick to troubleshooting this error number is that the error message returned to the client or application trying to connect is intentionally vague (the error message is similar for most errors, and the state is always 1). In a few cases, some additional information is included, but for the most part several of these conditions appear the same to the end user. In order to figure out what is really going wrong, you need to have alternative access to the SQL Server and inspect the log for the true state in the error message. I helped our support team just today solve a client's 18456 issues - once we tracked down the error log and saw that it was state 16, it was easy to determine that their login had been set up with a default database that had been detached long ago. In SQL Server 2012, there is a new feature called "contained databases" - I've blogged about it here and here. With this feature comes a new layer of security that may creep onto your radar if you use this functionality: contained user authentication failures. There are a variety of things that can go wrong here. If you connect with a contained user but forget to specify a database name, SQL Server will attempt to authorize you as a SQL login, and you will fail with state 5 (if there is no SQL login with that name) or state 8 (if there is also a SQL login with the same name and the password doesn't match). There is also a new state 65 which occurs if you have specified the correct username and contained database, but entered an incorrect password. The way that the authenti
