Commit of a modified version of Andrew Bartlett's patch that removes the
horrid utmp hostname parameter - now uses the client name instead.
Also tidies up some of the unencrypted password checking when PAM
is compiled in.
FIXME ! An pam_accountcheck() is being called even when smb encrypted
passwords are negotiated. Is this the correct thing to do when winbindd
is running ! This needs *SEVERE* testing....
Jeremy.
