When the client logs in with account name XYZ, the password used is' 123 '(external password). Our AA cluster gateway will automatically replace the password with the real password' 456 '(internal password) in SQLSERVER. This way, the external password for the client to access the database can change frequently, but the internal password for the corresponding account in SQLSERVER can remain unchanged.
