[Samba] Replication errors with LDAP and problems with NT machines
Hi all! I work as a computer technician for a small school and have recently upgraded our network to use samba servers. Our main computers are a PDC, a BDC, a file server and a backup server, all using Red Hat Fedora Core 3 as a base. The clients on our network consist of machines with Windows XP and a few with Windows NT. Everything seems to work just fine except for some minor but annoying problem. The XP machines work flawlessly but the ones with NT do ?disconnect? themselves from the domain now and then in a random way (or so it seems). My solution so far is to rejoin them in the domain by logging in locally as administrator. Sometimes, but that is even more rare, I have to delete the computer account in the LDAP database and recreate it. The PDC updates the BDC via LDAP replication (Slurpd). I do get some strange errors from this replication and I suspect this have something to with the strange behaviour since it?s the same computers that are in the error log that disconnect themselves. It could very well be two completely diffent issues though. I attach some config files which I think is the ones needed. If more info is needed please ask. I would be grateful for any help. Thank you! Thomas Wigren 1. Versions of software samba-3.0.10-1.fc3 openldap-2.2.13-2 2.
