Early indications show me that State 16 is an old, generic message, meaning the db couldn't be opened. Either the user lacks permissions or the server is inaccessible: sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/… –Danny Beckett Mar

Error 18456 Severity 14 State 8 But Password Is Correct
tweets as @AaronBertrand; and speaks frequently at major conferences, user group meetings, and SQL Saturday events worldwide. Troubleshooting Error 18456 I think we've all dealt with error 18456, whether it http://stackoverflow.com/questions/15515823/severity-14-error-state-16-on-our-sql-server-2005-login-failed-for-user-userna 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 http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx 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 SQ

Login failed for user September 8, 2016Pinal DaveSQLNo CommentsSome errors are historic and have the most common root cause. Sometimes we really don’t know why they happen and I have seen clients go nuts to identify the real reason for the problem. In a recent email interaction with one customer – who was migrating from Oracle to SQL Server. He kept telling me that they were getting login errors from their Java application. And even when they used the SQL Server Management Studio it was erroring out with Error 18456 code. They sent me a snapshot like this for login failed:This was not self-explanatory and as usual, I searched this blog to get a few posts around this error. I sent him this and said, if these don’t solve your problem – can you please send me more details. SQL SERVER – FIX Error 18456, Severity: 14, State: 6. Login failed for userSQL SERVER – FIX Error 18456, Severity: 14, State: 58. Login failed for userIn about an hour, I received a mail again stating the above were not solving his problem. He sent me a bigger screenshot as shown below:Though this was a good starting point, this was not good enough information for me based on what SSMS was sending as output.I reviewed the above blogs just to realize I had forgotten to give a bigger detail. A lot of these login failures are also logged in ErrorLog. I realized and asked the Developer to check in their error log. And incidentally, they figured out the actual root cause. Since he didn’t get back to me for 3 hours – it was my turn to ask what went wrong because I was curious to understand the actual reason. I got a screen shot as shown below and it explained quite a bit.If you are not sure where to get the ErrorLog, check the post: SQL SERVER – Where is ERRORLOG? Various Ways to Find ERRORLOG Location.On further investigation, it was learnt that their application was changing the password for their users in their application code, but since it was load balanced, it was getting into some mess. But I was glad how explicit and detailed information Error Logs give that helped this user.Have you seen and used such information in your environments
