samba - Jan 2014 - Error when adding user NT_STATUS_CONNECTION_REFUSED

Any idea what the following error message is describing and how to 
troubleshoot? Newly joined DC. Using Ubuntu 12.04 and Samba 4.1.4 from a 
tarball. Used samba-tool. Windows Users & Computers app gives error as well.

ERROR(ldb): Failed to add user 'usertest':  - 
../source4/dsdb/samdb/ldb_modules/ridalloc.c:547: No RID Set DN - 
Request for remote creation of RID Set for this DC failed: Failed to 
send MSG_DREPL_ALLOCATE_RID to dreplsrv at 1054: 
NT_STATUS_CONNECTION_REFUSED

Your new joined DC tries to ask the DC that owns the RID master FSMO 
role for a set of RIDs, but this machine refuses the connection. So your 
new DC doesn't have RIDs, what prevents you from creating users on that 
machine.

Is your replication working?
# samba-tool drs showrepl

Check, which of your DC owns the RID master role
# samba-tool fsmo show
Then have a look on that machine, if Samba works correctly on that 
machine. Maybe you removed this machine meanwhile and the role wasn't 
transfered to a different DC.
