[Samba] net ads leave failed.

[Vincent.Badier at alcatel.fr]

Hello all, 

I have the latest version of Samba (samba-3.0.21c) installed on a SLES9 
linux server, with all the related Suse packages.
I had link the server correctly to the domain, but discovered a pb with a 
workstation acting as mster browser. 
Since it is down, i have a bad result with wbinfo -t, althought net ads 
testjoin succeed. I beleived that either wbinfo -t result or net ads 
testjoin result tell if the server is correctly joined to the domain. Is 
there any explanation about the differences? 

I think there is a problem with domain link. when i do wbinfo -u winbindd 
daemon crash with the error in log : 
  INTERNAL ERROR: Signal 11 in pid 20631 (3.0.21c-3.1.4-SUSE-SLES9)
  [...]
  PANIC: internal error

To try to correct the problem, i wanted to leave the domain, and to rejoin 
it. Is it a bad idea? 

The problem is that net ads leave failed as well, with "ldap_delete_ext_s 
failed with error code 50". Is it an authentification problem? I can only 
get from LDAP source "#define LDAP_OTHER 0x50", so no help from there. 

Here are some step i did :

# net ads testjoin
Join is OK
# wbinfo -t
checking the trust secret via RPC calls failed
error code was  (0x0)
Could not check secret
# net ads status -> seems correct, got correct information
# net rpc trustdom list -Uuser1 -> Also correct, give the SID of trusted 
domains.
