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 https://blogs.msdn.microsoft.com/sql_protocols/2006/02/21/understanding-login-failed-error-18456-error-messages-in-sql-server-2005/ 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 http://sqlblog.com/blogs/aaron_bertrand/archive/2011/01/14/sql-server-v-next-denali-additional-states-for-error-18456.aspx 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

Yet, when I use the same user names and passwords from SQLCMD and from jdbc based clients like Squirrel, it works fine to connect to all three servers. I can also log into them from an XP machine w/ Sql Studio Express using the same user names and passwords. And of course, I have quadruple checked all the normal things like my caps lock is not on, I am not set up with an alternative language keyboard, I am really typing the exact same thing in both cases, etc. Anyway, why might I be getting a password mismatch error when the password is correct? Might it have something to do with the different versions of MDAC on the machines, and if so, is there a way to revert Windows 7 back to an older version of MDAC? sql-server share|improve this question edited Jun 22 '11 at 18:29 asked Jun 8 '11 at 21:45 jlarson 27631022 Using SQL Studio Express to manage databases on a SQL Server 2005?
