[Samba] After host name change: Failed to add user ... with error: The account's primary group is invalid

I've got Samba 3.5.6 (SerNet packages) running on Debian Lenny. User information is stored in LDAP via ldapsam:editposix. I changed both the host name and the workgroup name as I had to move the host to a new internal subnet.

I noticed that a new sambaDomainName entry was created (containing a new sambaSID). Unfortunately, the Administrator user still contains both the old sambaSID and the old sambaPrimaryGroupSID and thus does not have any rights. I tried to perform the following steps:

net -U Administrator%myadminpass -I localhost rpc user add myuser

and got the error message mentioned in the subject line. Consequently, the other steps failed:

net -U Administrator%myadminpass -I localhost sam createdomaingroup grmyuser
net -U Administrator%myadminpass -I localhost sam addmem grmyuser myuser

What's the correct procedure to get the Administrator account working again after a host name/workgroup name change so that I can continue to add more users?

Thanks in advance for any hints & kind regards,
