group meetings, and SQL Saturday events worldwide. Troubleshooting Error 18456 I think we've all dealt with error 18456, whether it be an application unable to access error 18456 severity 14 state 6 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 https://social.msdn.microsoft.com/Forums/sqlserver/en-US/12de6c4f-620b-4658-8f5f-cff2efe582c2/microsoft-sql-server-error-18456-severity-14-state-1?forum=sqlsecurity 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 http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx 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 authentication process works is, if SQL Server doesn't find your user in the contained database you specifies, it tries again at the server level, then gives up (it won't go check all the other contained databases in case you match there - I hope you agree that this is a good thing). If you don't specify a database in your connection string, then it won't succeed unless - by coincidence - you have a contained user with the sa

In this blog, I am going to share few possible causes of the error and their solution. First, we need to understand that due to security reasons, SQL Server doesn’t send more information about this error message to client.
