Kernel Crash with FC3 [glibc?]

[Kyrre Ness Sjobak]

I have also seen problems with nscd. On a stable FC3 machine with LDAP
auth., it refused to login a user when nscd was turned on, it said the
user didn't exist. UID#->username mapping worked, though.

Stopping nscd allowed the user to login instantaniously.

Using LDAP auth
