Relevant BUGIDs: 112540
Purpose of commit: minor security bugfix
Commit summary:
---------------
Fixes for the password helper binaries.
Before, there was no check that the password entered was actually that
of the intended user being authenticated. Instead, the password was
checked for the requesting user. While this disstinction sounds like a
security hole, its actually not been a problem in practice. The helper
binaries have only been used in the case that the application is not
setuid-0 and as such even if an improper authentication succeeded, the
application could not change its uid from that of the requesting user.
