Suse 10.1 Setting up PDC

I am setting up a PDC using suse 10.1 but I get the error (failed to modify entry: structural object class modification from ‘sambaDomain’ to ‘inetOrgPerson’ not allowed at /usr/sbin/smbldap-populate line 464, <GEN1> line 21.) when I run /usr/sbin/smbldap-populate command

What Am I not doing right?

I hope you are aware of the fact that openSUSE 10.1 (or do you mean a SLED/SLES version?) is long out of suport. As a consequence there will be very few people who can try on their own systems to recreate your problem.
