[Samba] DC priority, BDC prob with domain groups

Setting "announce version = 4.5" in smb.conf on BDC2 did not change
anything.  (The other samba domain still use 4.9 as the default version.)
Windows clients will still connect to BDC2 (if it is running.)  On each DC,
net getdomainsid and getlocalsid show that the local sid on each machine is
the domain sid.

BDC2# net getdomainsid
SID for local machine BDC2 is: S-1-5-21-xxx-xxx-x99
SID for domain DOMAIN is: S-1-5-21-xxx-xxx-x99

BDC2# net getlocalsid
SID for domain BDC is-xxx-xxx-x99

Pdbedit -Lv, wbinfo -u and wbinfo -g all seem to give the same results


BDC# wbinfo -t
checking the trust secret via RPC calls succeeded

Subject: DC priority, BDC prob with domain groups

I have the following setup:
     PDC:  Samba 3.0.37 on Solaris 10
     BDC1: Samba 3.0.37 on Solaris 10
     BDC2: Samba 3.4.3 on Solaris 10

Samba 3.0.37 is the bundled version of Samba.
Samba 3.4.3 is compiled from source.

BDC2 is a recent addition to the network.
All machine use LDAP as the backend for everything.  They use winbind to 
handle a domain trust with another domain, but otherwise isn't needed.

If I start samba on BDC2 and logon to an XP  (or Win 2003) Machine, the 
logon will be to BDC2.    This can be verified with echo 
%logonserver%.    Rebooting the XP machine is probably not necessary to 
see this.

If I login as the domain administrator, I am effectively not considered 
a member of the local administrator group.  If I look at the local 
Administrator group I will see the DOMAIN/Administrators as members.     
But I am unable to install software,  see all local files, add users to 
local groups etc.

"OS level" on all three DC's was not explictly set, so was 20 by 
default.  I changed BDC2 to "os level=0" and set the PDC to "os 
level=33."  I did not restart samba on PDC.   It seems to be a browsing 

I still logon to BDC2.

So I have two issues:

1-  How to make sure that the PDC (or PDC and BDC1) use used in 
preference to BDC2.  I assume that something about BDC2 having a newer 
ver of samba is getting it priority.

2.  What is wrong with the domain members in local users group.   This 
may be a BDC config in general issue (and I just never found it because 
BDC1 never took precendence over PDC) or it may be  something to do with 
Samba 3.4.x vs 3.0.x.
