[Samba] Could not join the domain - Samba and Openldap

[iordonez at nature.berkeley.edu]

Our PDC accidentally crashed and to eliminate down time, I quickly set up
one of the BDC to be the new PDC. I copied all the configuration file of
PDC to the BDC.  These files are slapd.conf, ldap.conf, smb.conf, etc.... 
Now that the PDC is up and running again, I want to put it back to the way
it was since the BDC did not run to a functional state anyway.

Here is a snippet of the debug when I run "net rpc testjoin -d 10" on PDC.

PDC IP = 192.168.1.2
BDC IP = 192.168.1.3

Why am I getting all these messages about BDC's IP Address (192.168.1.3)
when I run the "net rpc testjoin" command on the PDC?  I can ping the PDC
by IP and by netbios name.   Running nmblookup on the PDC gives me
positive response.  I am running samba 3.0.32 with openldap backend.

Any advise is greatly appreciated.

Thanks,
