PDC migration from smbpasswd backend fails
Last modified: 2012-09-19 22:23:09 UTC
When trying to migrate a PDC from Samba 3 to Samba 4.0.0rc1, the provisioning script fails with an error, since the Administrator SID is not -500 (it is autogenerated from the uid, and thus at least 1000).
Migrating to tdbsam and changing the SID manually (or deleting the Administrator user entirely) fixes the issue, but this should probably still be fixed/worked around somehow.
