[Samba] PDC problems

[Jason Baker]

I have a Samba PDC, running on Centos 4. The samba version is 
3.0.23d.30. I have an LDAP backend. Everything seems to be running fine. 
I recently configured a BDC, to help with load balancing and to act as a 
backup in the event the PDC went down. Before I installed the PDC, when 
a new user logged into the domain, their home directory on the PDC was 
automatically mapped to the drive letter U. Now that the BDC is running, 
when a new user logs into the domain, their home directory is 
automatically mapped to U, but it points to their home directory on the 
BDC and not the PDC. This created a problem at first because there were 
no home directories on the BDC. I mounted all home directories from the 
PDC to the BDC and it works fine, but why is the BDC the default home 
when a user logs in? Also, when a new user logs in, their login script 
is being pulled from the netlogon share on the BDC and not the PDC, so I 
had to make a copy of the netlogon directory from the PDC to the BDC. 
I'm assuming that I have something configured incorrectly. I have 
included the samba conf files from both PDC and BDC.
