[Pkg-samba-maint] Bug#484309: interdomain trusting fails

[Peter Slickers]

Package: samba
Version: 3.0.30-2

After upgrading all samba-packages from 3.0.28a-3 to 3.0.30-2, trusted accounts
are no longer recognized, and the command 'wbinfo -t' fails. After downgrading
to 3.0.28a-3, everything works fine again.

I'm running a PDC which is trusting another domain which is run by a
Windows-NT4-SP6 domain controller. Users of the NT4 domain can login
to the samba domain. This works fine with samba 3.0.28a-3. After upgrading
to 3.0.30-2, it is no longer possible for the NT4-domain users to
login to the samba domain. In addition, the command 'wbinfo -t' fails
on the samba server.

wbinfo -t
checking the trust secret via RPC calls failed
error code was NT_STATUS_DOMAIN_CONTROLLER_NOT_FOUND (0xc0000233)
Could not check secret

I have also traced the output of winbindd in interactive mode
generated after firing up the 'wbinfo -t' command:

/usr/sbin/winbindd -n -i -d10

After downgrading to 3.0.28a-3, wbinfo runs successfully:

wbinfo -t
checking the trust secret via RPC calls succeeded
