Troubleshooting Error 18456 I think we've error 18456 state 5 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 sqlstate 28000 error 18456 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 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

SQL Server > SQL Server Security Question 0 Sign in to vote On a 2008 x64 instance I have a DB with several SQL logins. When trying to login using SSMS with the problem login, i get a Error: error 18456 18456, Severity: 14, State: 40. Failed to open the database specified in the login properties. If I give the login sysadmin privileges it goes right in, but this obviously isn't the fix.Any thoughts?Thanks Friday, October 16, 2009 11:35 AM Reply | Quote Answers 0 Sign in to vote error 18456 state As you said , giving sysadmin access is not at all the workaround. Have a look at my article http://www.sql-articles.com/Joomla/articles/troubleshooting/troubleshooting-login-failed-error-18456 . This state normally means the default database for the login\ user is not available . SOLUTION: 1.Try bringing the default db of the login online. 2.Change the default db for that login to be master or any other available database.
