The problem was that DC1 had it's host names in the wrong order in 
/etc/hosts. DC2 didn't have any names there, so it relied on DNS which 
returned the correct FQDN.

Once I fixed /etc/hosts on DC1 as below, the resolving of usernames now 
takes 10 seconds. I can live with that, even though Samba + OpenLDAP was 
much faster in this aspect.

That check-script should be a standard part of every DC-install :)

Our uids pre-date Debian. They are a mix of Solaris and Slackware usernames 
so we start at 500. This will fix itself over time, there aren't many users 
left within the 500-999 range.

Thank You.
