[Samba] net ads join fails with "Operations error" ?

[Tim]

Hi all.

I'm having a problem joining an ADS domain with Samba 3.0.5.

The machine account has been set up on the server in a similar way to
another system which has joined successfully.  The error I'm getting
is kinda vague, and I have no idea what it means:

---

ads_join_realm: Operations error
[2004/07/28 16:32:36, 2] utils/net.c:main(792)
  return code = -1

Does anybody know what "Operations error" actually means?

What have I configured incorrectly?

The command I'm running is:

# net -d 3 ads join "UAT/WISE/Servers" -U kimjeo

..and my config looks like this:

security = ADS
netbios name = SAMBA3DWEB
workgroup = xxx
realm = xxx.xxx.xx.xxx
name resolve order = lmhosts host wins
wins server = 10.xx.xx.xx
winbind separator = +
winbind uid = 65534-65534
winbind gid = 65534-65534
winbind enum users = no
winbind enum groups = no
winbind cache time = 60
password server = *

Any help or advice is appreciated.

Regards,

Tim.
