Comment 0 for bug 1819197

uid and gid appear to not map properly from nfsidmap in a nfsv4 with sec=krb5. UID and GID are mapping properly on CentOS server and CentOS client. Ubuntu nfs client file permissions are honored, but display is `ls -lan` command are incorrect.

$ cat /var/log/syslog |grep nfsidmap
