Question : sp_change_users_login

when i run
EXEC sp_change_users_login 'Report'
i get one row output..

but when i run the next line of code, it does fix it..
EXEC sp_change_users_login 'Auto_Fix', 'user'

any thoughts on how to go about seeing what the problem is.

thanks

Answer : sp_change_users_login

that user is an orphan user ( the internal user id's could be different across the servers , and the second sp make them matchable )
