Indeed. The only way to safely import a list of users who already have
SIDs is to migrate them to Samba 4.0's AD DC using one of the supported
These are 'samba-tool domain join dc' and 'samba-tool domain
The reason is that we have to ensure that we never re-allocate the same
SID to a new user later. For that reason, we have protection in the
domain controller code to prevent the administrator specifying the SID.
