01d681faa3 external auth: allow to map multiple login username to a single account
some external auth users want to map multiple login usernames with a single
SGTPGo account.
For example an SFTP user logins using "user1" or "user2" and the external auth
returns "user" in both cases, so we use the username returned from external auth
and not the one used to login

Fixes #125
