How to identify and fix the orphan users in MSSQL Server?

Orphaned user in MSSQL means that a user who is present at the database level but the relevant login doesn’t present on the server. This kind of user can be created when you perform database migration. 

By default, MSSQL Server login is mapped with SQL Database user. If this is not defined properly for MSSQL Server principal then the user will not be able to log in successfully for its database and this user is called an orphan user.

Please find the below SQL query to find the orphaned users in MSSQL.

USE
USER DATABASE
EXEC SP_CHANGE_USERS_LOGIN ‘REPORT’
GO

The following are the steps to fix orphaned users using ORPHANED USER SID

If there are any orphaned users, then we can create its login by using orphaned user SID.

Syntax:

USE
MASTER
CREATE LOGIN [LoginName] WITH PASSWORD = ‘[email protected]’,
SID = 0xF0C10D1C8EDFGA06435B07DAD54FFAE
