Hi,
I removed a Samba 4 DC of the domain and after I removed the server partner
with this command:
ldbdel --url=/var/lib/samba/private/sam.ldb
CN=SAMBA4-DC-OLD,CN=Computers,DC=empresa,DC=com,DC=br
Now, I have the follow problem:
samba-tool drs showrepl
Warning: No NC replicated for Connection!
Connection --
ERROR(<type 'exceptions.IndexError'>): uncaught exception - list index out
of range
File "/usr/lib/python2.7/dist-packages/samba/netcmd/__init__.py", line
176, in _run
return self.run(*args, **kwargs)
File "/usr/lib/python2.7/dist-packages/samba/netcmd/drs.py", line 180, in
run
c_server_dns = c_server_res[0]["dnsHostName"][0]
How I solve this problem ?
