Nope, you can't currently do "user at domain" auth for sql and "user" for PAM. You could try using passdb checkpassword instead though, which allows you to script it any way you want.

Also userdb passwd can't do that.

I've thought of adding a generic passdb/userdb { auth_username_format } setting, but that doesn't exist yet. Would be easy to do though..
