This doesn't seem normal.  The samba attribute should be added by the
vampire. So I would suspect some problem in the communication with the
PDC and double check that on the samba box 

1) you have the domain SID as local SID
2) you have joined the domain as BDC
3) you can see the attribute with net samdump

At distance this is a hard guess. I suggest that you look at the ldap
log to get an idea what happend.
