[Samba] problems adding machines after upgrade - sambaSID attribute incomplete!

[Pablo Chamorro C.]

Some days ago we were able to add machines to our Samba+OpenLDAP domain, 
but after we decided to update samba from 3.0.5a to 3.0.21c now we can't 
do that anymore!.

In adding a machine, the "wellcome to domain XXX" message appears, but 
after rebooting the machine it doesn't works!.  Looking the openldap 
entries, now we are having these kind of entries:

sambaSID: S-1-5-21-2502698289-3639879065-4582
sambaPrimaryGroupSID: S-1-5-21-2502698289-3639879065-7544774837-515

note that "one part" of the Samba SID is missing, the correct should be: 
sambaSID: S-1-5-21-2502698289-3639879065-7544774837-4582

so, I tried to fix the sambaSID attribute by hand on the openldap server 
using phpldapadmin but no luck.  Also, I tried with the last 
smbldap-tools-0.9.2-1 without success.  Windows shows "please check 
your password".  How can this be fixed?  Our openldap samba.schema was 
taken from samba 3.0.14a and our PDC is red hat 9.

Thanks,

Pablo
