[Samba] Nmbd crash with failure to open wins.tdb

[Enachioaie Alexandru]

Hello,

I've found this issue reported only once before but no real answer was
provided/found.

I am trying to migrate from an old 2.0.7 server, but the bundled
install 3.0.24 on FC6 is giving me major pain. Putting aside the
actual configuration and user migration which I need to figure out,
the problem is that nmbd refuses to start with the following errors in
the log:

[2007/02/26 14:05:26, 0] lib/messages.c:message_init(127)
  ERROR: Failed to initialise messages database
[2007/02/26 14:05:26, 0] nmbd/nmbd_winsserver.c:initialise_wins(580)
  initialise_wins: failed to open wins.tdb. Error was Permission denied

I've checked the permission on the locks directory, I've tried
chowning, chmodding 777, nothing seems to fix this, and I can't figure
out why. Here's relevant file stats:

-rw-r--r-- 1 root root   696 Feb 27 08:45 sessionid.tdb

The even weirder part is that when I manually start nmbd (eg: from cli
using nmbd -D, it writes to wins.tdb just fine and starts up).

Also if there's any details pertaining to proper migration please do
let me know because I have not had extensive experience with samba and
this is kind of urgent (yes, I have googled for information but it is
really scarce pertaining migration).
