DBCC FLUSHAUTHCACHE is a database console command (DBCC) in Microsoft SQL Server that can be used to clear the server-level authentication cache. Clearing the authentication cache can be useful for ensuring that changes to the authentication configuration or permissions are applied immediately, or for troubleshooting issues with authentication.
To use DBCC FLUSHAUTHCACHE, you do not need to specify any options or arguments. Simply execute the command as shown below:
-- Clear the server-level authentication cache
DBCC FLUSHAUTHCACHE;
The output of DBCC FLUSHAUTHCACHE will be a message indicating whether the operation was successful or not. If the operation was successful, the server-level authentication cache will be cleared.
Please note that DBCC FLUSHAUTHCACHE is a global command and will affect all connections to the database engine. As a result, it is generally best to avoid using DBCC FLUSHAUTHCACHE in production environments, or to use it sparingly and only when necessary.
DBCC FLUSHAUTHCACHE is a useful tool for clearing the server-level authentication cache in SQL Server, but it should be used with caution.
