mancha 5e7435b792 system/gdm: Fix crypt() usage with glibc-2.17+
Starting with glibc 2.17 (eglibc 2.17), crypt() fails with
EINVAL (w/ NULL return) if the salt violates specifications.
Additionally, on FIPS-140 enabled Linux systems, DES or MD5
encrypted passwords passed to crypt() fail with EPERM (w/
NULL return).

Slackware-current has transitioned to glibc 2.17 and as you
might be aware from reading my posts on LQ, I have dedicated
time to fixing userland which does not adequately handle
crypt() returns given the new behavior.

gdm is negatively affected and my attached patch (against
gdm 2.20.11) addresses this.

This is in anticipation of a new Slackware release but can
be applied to the SBo package for Slackware 14.0 since it is
backwards compatible and should not affect behavior on glibc
2.15. It would be good if my assertion were tested.

[rworkman] Yeah, it seems to work here :-)

The Gnome Display Manager (GDM) is a display manager that implements all 
significant features required for managing local and remote displays. 
For full information about GDM features, refer to the documentation.

If you want xscreensaver to recognize gdm and add a "New Login" button
to the unlock screen, add this line to your ~/.xscreensaver file:
  newLoginCommand:       gdmflexiserver -ls
