From b064eca2cf6440bf9d5843b24cc4010624031694 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 22 Feb 2011 15:44:32 -0800 Subject: NFSv4: Send unmapped uid/gids to the server when using auth_sys The new behaviour is enabled using the new module parameter 'nfs4_disable_idmapping'. Note that if the server rejects an unmapped uid or gid, then the client will automatically switch back to using the idmapper.
