Hi list,
I'm trying to work on a script that should not care what DC is up, as long
as one is. I want to be able to use the samba-tool command in our Samba-AD
domain from a domain member, using kerberos.
I have the kinit command granting me a ticket. I want to use that ticket to
remotely add users to the domain controller, while I'm on the domain
member's console. For example:
root at fileserver.example.com:~# kinit administrator
Password for administrator at EXAMPLE.COM:
root at fileserver.example.com:~# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: administrator at EXAMPLE.COM
Valid starting Expires Service principal
08/01/19 13:03:00 08/01/19 23:03:00 krbtgt/EXAMPLE.COM at EXAMPLE.COM
renew until 09/01/19 13:02:59
root at fileserver.example.com:~# samba-tool user list --kerberos=yes
ERROR(ldb): uncaught exception - ldb_search: invalid basedn '(null)'
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/user.py", line
445,
in run
attrs=["samaccountname"])
The commands run fine from the domain controller, but we want to run the
commands from a member server. Is this possible, either using
usernames/passwords or kerberos? We are on Debian 9.6, running Samba
4.5.12-Debian (Yes, I know it's EOL for Samba, but it's the latest in
the
repo).

I should have been more specific. I'm trying to add users; I figured listing the users was a good test. I'm sure it's expected, but I'm now seeing the following: # samba-tool user create test.user -H ldap://dc1 New Password: Retype Password: ERROR(ldb): Failed to add user 'test.user': - LDAP error 1 LDAP_OPERATIONS_ERROR - <00002020: Operation unavailable without authentication> <> I tried using the -U and -P switch (as a test), and it claimed that the Administrator was "unable to get access to CN=....". I used the "--kerberos yes" switch with the -H ldap://dc1, and that works!
