Defaults to `false` (for now). So the /graph/users endpoints are
read-only by default, which should be the default configured against
and existing external LDAP server.
By default the GraphAPI will generate the UUID itself now instead of
relying on the LDAP server to generate a valid entryUUID attribute. This
can been be switched off via the new `use_server_uuid` toggle in the
LDAP config.
This adds basic support for creating users via the GraphAPI
LDAP backend. This currently just maintains the bare minimum
Attributes for the inetOrgPerson objectclass.
