[Samba] User names not replicating to secondary DC

[L.P.H. van Belle]

Your setup is in consistant. 

> 127.0.0.1       localhost.localdomain   localhost

> 127.0.0.1       localhost

I suggest run my debugscript, make sure the servers there base setup is the same. 



+ set both DC's there /etc/resolv.conf 
search msi.mydomain.com mydomain.com

# IF THIS IS DC1 
nameserver 172.23.93.26
nameserver 172.23.93.25
nameserver 172.23.93.3

# and for DC0 
nameserver 172.23.93.25
nameserver 172.23.93.26
nameserver 172.23.93.3

But the first resolving it the dc's its one ip. 


Then reboot them. 
And then check again. 


Greetz, 

Louis
