In case its not clear, he means groups that are referenced from udev,
but are not defined in /etc/group.

So, on boot, the NSS resolver tries to find the group in /etc/group and
this fails.

The NSS resolver then tries to find the group in LDAP, but surprise,
surprise, the LDAP server doesn't respond. Keep waiting, it has to
respond soon... No answer. Lets try again... wait for it...

When of course the reason that there is no response is because udev
starts first, before networking or slapd is started.

So you get all these silly errors displaying on screen for what is a
normal condition.

If the timeouts are too large, it also can delay the boot. Significantly.

(supposedly libnss-ldapd - based on the description - is suppose to
solve this also - not sure how - I haven't been able to get it working
entirely satisfactorily).
