+       In contrast to read only backends like idmap_rid, it is an allocating
+       backend: This means that it needs to allocate new user and group IDs in
+       order to create new mappings. The allocator can be provided by the
+       idmap_tdb2 backend itself or by any other allocating backend like
+       idmap_tdb or idmap_ldap. This is configured with the
+       parameter <parameter>idmap alloc backend</parameter>.
