The XYZ group has around 10 users in there who are successfully able
Microsoft Sql Server Error 18456 Sql Server Authentication
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: 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/

Microsoft Sql Server Error 18456 Login Failed For User
0 Vous le savez sans doute déjà, un login failed SQL Server n’envoie quasiment aucun détail sur les raisons de l’échec au client, http://dba.stackexchange.com/questions/37564/login-failed-for-user-error-18456-severity-14-state-11 dans un but de sécurité du système (le client en question pourrait être un hacker en train de tester le système). Par contre, le DBA a accès à l’erreur côté serveur qui fournit un peu plus d’informations sur les causes exactes, notamment grâce au ‘State’ (ou https://blogs.msdn.microsoft.com/support_sql_france/2012/02/20/error-18456-severity-14-state-11-et-state-12-login-failed-sur-sql-server-2005/ état) de l’erreur 18456. http://blogs.msdn.com/sql_protocols/archive/2006/02/21/536201.aspx discute de la plupart des scénarios. Vous noterez que 2 valeurs sortent du lot : Logon Error: 18456, Severity: 14, State: 11.Logon Login failed for user ‘domain\user'. [CLIENT: xxx.xxx.xx.xx] et Logon Error: 18456, Severity: 14, State: 12.Logon Login failed for user toto. [CLIENT: xxx.xxxxxx] Le blog et ses commentaires reflètent en effet une multitude de causes possibles, regroupées sous le terme générique ‘Valid login but server access failure’. J’ai pu récemment découvrir une nouvelle cause à cette erreur que je n’ai vu décrite nulle part : la tentative de connexion à un ENDPOINT TCP sur lequel l’utilisateur n’a pas le droit (alors même qu’il a les permissions d’accès au serveur SQL). Le state 11 correspondant à une tentative de connexion ‘trusted’ (utilisant l’authentification Windows) et le 12, à une connexion ’non-trusted’ (utilisant l&rsq

I keep getting the standard login failed error and in the error log I'm seeing "Error: 18456, Severity: 14, State: 11." The login is using windows authentication - here's the weird bit. I can login fine from my own machine using the same authentication, just not when I'm on the machine the database is installed on. Any ideas?

When an administrator logs on, this version of Windows creates two separate access tokens for the user: a standard user access token and an administrator access token. The standard user access token contains the same user-specific information as the administrator access token, but the administrative Windows privileges and SIDs have been removed. The standard user access token is used to start applications... When you're logged in locally your administrator token is stripped. Since you granted access to your instance to BUILTIN\Administrators, y
