This is true even if there is a login id that matches the user, since there is a GUID (called a SID in Microsoft-speak) that has to match as well. This used to be a pain to fix, but currently (SQL Server 2000, SP3) there is a stored procedure that does the heavy lifting.

1. Log in to Server P, open SSMS (SQL Server Management Studio) and connect to an existing instance (in our case its instance ABC).
2. Open New Query window, and then run the below script : USE master. GO. IF OBJECT_ID ('sp_hexadecimal') IS NOT NULL. DROP PROCEDURE sp_hexadecimal. CREATE PROCEDURE sp_hexadecimal.
3. The script executed in Step 2 will create two stored procedures in the master database. The created stored procedure is as below : sp_hexadecimal.
4. Now login to Server Q, open SSMS (SQL Server Management Studio) and connect to the instance where we need to transfer (replicate) these logins (in our case its instance XYZ).
5. Open new Query window on instance XYZ, copy the output script (generated on instance ABC after the execution of step 3). Execute the script and it will create the logins with original passwords and correct SID.

1. Create a Windows user. In Active Directory, we will create a Windows user account u007. We can execute a Windows Management Instrumentation Command-line (WMIC) from a command prompt as below to get the domain level SID for Windows user account u007.
2. Create User Defined Function. Before proceeding any further, we will execute the script below to create a user defined function ufn_StringToSID on the 3 SQL Server instances – SQLP1, SQLP2 and SQLP3.
3. Add Windows user account to SQL Server. We will now add Windows user u007 into SQLP1. 1 2 3 4 5 6 7 USE [master] GO. CREATE LOGIN [SQLDC\u007] FROM WINDOWS WITH DEFAULT_DATABASE=[master],
4. Grant Windows user u007 privilege to a user database. When the login u007 is granted access to a database in SQL Server, it creates a database user which maps back to the instance level login.
5. Windows login automatically maps SID. We can now backup and restore the [SQLShack] database to SQLP2. We will add Windows user u007 to SQL Server instance SQLP2.
6. Domain level SID do not change. Since the domain level SID did not change, the binary SID value in SQL Server sys.server_principals will remain the same.
7. New Windows user with same name. In some organizations, Windows user accounts are created in an incrementalnumbering fashion. A user account is dropped when an employee leaves the organization, and the same number sometimes gets re-used over time.
8. Restore user database and add new login on SQLP3. Now we restore SQLShack database to SQLP3 and add the new Windows user u007 here. In this scenario, we have a mismat in SID value stored in SQL server SQLP3 between the login and the database user.
