You will get errors like this because the groups will already have been created before the users and groups are migrated, you can ignore these.

Soon after when adding users to groups, the process bombed out with
the following error:

ERROR(<class 'samba.provision.ProvisioningError'>): uncaught exception -
ProvisioningError: Could not add member
'S-1-5-21-2342696748-4272319941-312989834-1001' to group
'S-1-5-21-280721883-191778108-123917971-512' as either group or user record
doesn't exist: Base-DN '<SID=S-1-5-21-280721883-191778108-123917971-512>'
not found

Why does the user have a different SID to the group ?

That would make them members of different domains.

Is it like this in your old domain ?
