Hi All,

just wanted to report a success with some issues.

I have installed and configured the Version 4.0.0alpha15-GIT-f00d258 on 
Ubuntu server 10 with Python 2.6.6, "BIND 9.7.2-P3 built with 
'--with-openssl' '--with-gssapi' '--enable-threads' 
'--disable-openssl-version-check'" with functional level 2008_R2

Windows server 2008_R2 as additional domain controller using the dcpromo 

All went well and replication is working fine as i do not see any 
failures using "samba-tool drs showrepl" also users created in any of 
the domains are showing up in both,
However i did struggle to get the dnsupdate working but in the end that 
also worked.

I have some of queries

1. when i use the command "samba-tool drs showrepl" the last line says 
"Warning: No NC replicated for Connection!" what is this and how can we 
resolve it.

2. Also the replication of sysvol will work??

3. How many number of additional domains can i add to this domain controller

4. When i tried to add the windows server 2003 R2 to this domain using 
the dcpromo command, it did not add it and exit saying the version is 
not supported (do not have the exact message at this time)

5. when i tried to remove the additional 2008 R2 domain controller from 
the samba 4 DC it ends up with the message stating "domain is very busy 
to perform the request try later"

6. also i have this following error in the windows 2008 event logs
