When returning to a machine that has been sitting for a while (1 hour +)
while all users are logged out, the gnome based login manager fails any
ldap login aprox. 6 times before allowing a successful login. Below are
my logs from /var/log/auth.log:

--------
After this error (falsely showing that login failed) I am finally able
to actually log in. It is worth noting that this first successful login
occurs after what appears to be an x-session restart, as the screen
blacks out for about 2 seconds and then the login window launches fresh.
