I'm wondering what the difference is between the two wbinfo functions,
"getdcname" and "DSgetdcname". The help is not very helpful
here:
--dsgetdcname /|domain|/
Find a DC for a domain.
--getdcname /|domain|/
Get the DC name for the specified domain.
I have a Samba4 PDC that is returning different results for these
depending upon whether it's run on the PDC itself, or on a member
workstation; I'm trying to determine if this is related to group id
mapping issues.
On the PDC itself, "getdcname" just plain fails, with "Could not
get dc
name".
But "dsgetdcname" returns what seem like valid results in both cases,
but with subtle differences, such as with or without leading "\\" in
names, and with netbios names in one case and an IP address in the
other. Lastly, the 3rd line of output is either a "1" or a
"2", but I
have no idea what that signifies.
Can anyone clarify the output of dsgetdcname, and if this is normal?
ON THE PDC:
mikem at galactica:/etc/samba$ sudo wbinfo --getdcname musicplace
Could not get dc name for musicplace
mikem at galactica:/etc/samba$ sudo wbinfo --dsgetdcname musicplace

The results on the member server should be more reasonable. We will use just one winbindd codebase from Samba 4.2 on, so that should be better in the future.
