[Samba] PANIC: Could not fetch our SID - did we join?

[Linus Hedström]

Hi,

I have some problems running Samba and Winbind 3.0.22 in a AD, kerberos 
environment.

I have seen previous posts on several forums about this problem but 
haven't found any solution for it yet.

I have no problem with the default Samba package that comes with Ubuntu, 
3.0.14a.
But I do wan't to upgrade and the only option in that case seems to be 
to compile it.

I compiled it with the following options:
./configure --with-winbind --with-configdir=/etc/samba 
--with-logfilebase=/var/log/samba --with-pam_smbpass --with-pam

"net rpc join" and "net ads join" added the computer successfully to the AD.

net ads status and such commands give successful results and the 
kerberos connection works.

But, when starting winbind I do get this:

Where do Winbind look for the SID?
net getlocalsid shows the SID number.

None of the wbinfo commands works.
wbinfo -t:

checking the trust secret via RPC calls failed
error code was  (0x0)
Could not check secret


Part of my smb.conf, everything but the shares.:
