[Samba] Problem with Samba 3.4 Franky: Internal Error starting Samba3
Hi all,
I got a problem while trying to set up a Samba 3.4 Server in hybrid-mode.
After trying for some time I managed doing a merged-build of Samba3 and
Samba4 and I can now start samba4 without getting errors. However, the
same is not true for Samba3: starting it, I get the below error message.
Has anyone an idea about what the reason could be? Did I miss anything
during build/setup?
Thank you very much in advance for your help! If you need any further
information, please let me know.
Best regards
Chris

[Samba] Problem with Samba 3.4 Franky: Internal Error starting Samba3
I've investigated further onto this problem by starting smbd with debug
level 10. The "no version information available" message seems not to
be
the problem. It further looks like smbd can generally connect to the
Samba4-ADS ("pdb backend ads has a valid init" and several successful
pathtree_add, though my interpretation might be wrong).
The real problem seems to be connected to the user:
-------- snip --------

uid_to_sid: winbind failed to find a sid for uid 0
push_sec_ctx(0, 0) : sec_ctx_stack_ndx = 1

Create local NT token for S-1-22-1-0
Cache entry with key = IDMAP/SID2GID/S-1-5-32-544 couldn't be found
-------- snap --------
To my understanding, winbind cannot find a sid for user root (who has
uid 0). That's probably due to the fact that I started smbd as root user
for testing purposes.
Unfortunately this is where my knowledge ends. I'm a rather newbie to
Samba and LDAP, so help is really appreciated. I'm quite sure it's just
a small thing I missed.
Can anyone help?
Thx!
