hi there--

i've run into this problem (or something very similar) with the
version of gdm in ubuntu 5.10 (gdm 2.8.0.5-0ubuntu1).  my
/etc/nsswitch.conf uses "ldap compat", and i've removed nscd entirely.
i'm not using LDAP for PAM at all (preferring krb5 authentication).

Thanks to the suggestions by Rob Caelers in this bug, i looked into
problems with gdm_close_all_descriptors(), and reported my findings
upstream to what looks like the relevant gdm GNOME bug [0].  With
Brian Cameron's help, i found and removed a single offending call to
gdm_close_all_descriptors() in daemon/display.c, and now gdm
successfully works for logging in.

the patch i used against the ubuntu version was this:

diff -Nur gdm-2.8.0.5/daemon/display.c gdm-2.8.0.5.new/daemon/display.c
- --- gdm-2.8.0.5/daemon/display.c	2005-07-19 03:53:42.000000000 -0400

 	/* No error checking here - if it's messed the best response

i hope this helps other people to resolve this bug.  let me know if i
can be of further assistance with it.
