On a SL 7.3 + updates, and a 7.4 machine I was seeing trouble mounting sec=krb5 nfs mounts. audit.log had a lot of: type=AVC msg=audit(1504198638.609:3046): avc: denied { read } for pid=17510 comm="rpc.gssd" scontext=system_u:system_r:gssd_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=key type=AVC msg=audit(1504198638.609:3047): avc: denied { write } for pid=17510 comm="rpc.gssd" scontext=system_u:system_r:gssd_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=key Ran audit2allow to create a local policy and that got mounts working again. Although I think I've seen these on machines without ill effects as well, but not sure.
