SQL Server always on switch host login and user cannot match solution

SQL Server always on switch host after login and user cannot match, looked for a long time no solution was found, and later asked Microsoft, said that because login in the login host SQL Server instance SID, because the server before the SQL The SID of the server instance is different, resulting in an unmatched match.

The solution is as follows: first create login and user in one host, run out the login script with SID with the following two SP, run the footsteps on the secondary server separately, generate login with SID, so all server sql The SID for login in the server instance is the same, switch auto-match OK again.

1. The SP calls the second SP and runs the login step with SID
