Only the first id mapping must refer to root. And by first I mean in a sorted array of mappings. For instance: <idmap> <uid start='1' target='1001' count='1'/> <gid start='1' target='1001' count='1'/> <uid start='0' target='1000' count='1'/> <gid start='0' target='1000' count='1'/> </idmap> is okay.
