Bug#251088: xdm: remove pam_setcred() call from session.c so libpam-heimdal will work with xdm

[coldwell@physics.harvard.edu]

I've actually been working on patches to both libpam-heimdal and xdm.

In xdm, I simply replace the second call to pam_setcred (the one in
xc/programs/xdm/session.c) with pam_open_session.

In libpam-heimdal, I replace the existing open_session/close_session
no-op functions with functions that setup and destroy the credentials
cache.

If I get this working, I would be happy to submit the patches for
review/inclusion.
