Fix for ticket 61

[Tomas Mraz]

I'm reposting the patch with the fix for ticket 61 here. Basically we
need to use the first user name from the list and not the whole list.

OK to commit?

This pam_ftp patch got lost during the vacations. Ping? Anybody wants
to review the patch? I will commit it in a week if nobody objects.
