Hey Folks! Hope everyone is doing great! Question.  Tried a few sources to solve the UID and GID NFS mapping ability I would like to implement.  Mounting NFS Ganesha using *sec=sys* works but as soon as I use krb5, krb5i, krb5p etc I get 'permission denied' on the UID that IS the owner of that folder. Tried idmapd, as well as this suggestion: UID_GID_Mapping = NFSv4_ID_Mapping in FSAL which obviously didn't work.  So wondering, what is the proper way to get UID and GID mapping working with NFS Ganesha and GlusterFS using *sec=krb5** ?   Would love to look at a working example with sample configurations if possible. My config: [root@nfs01 glusterfs]# cat /etc/ganesha/ganesha.conf /etc/ganesha/export.conf|grep -v "^#" /etc/ganesha/ganesha.conf LOG {         Components {                  ALL = EVENT;         }         Facility {                 name = FILE;                 destination = "/var/log/ganesha/ganesha-rgw.log";                 enable = active;         } } NFSv4 {     Lease_Lifetime = 20 ;     IdmapConf = "/etc/idmapd.conf" ;     DomainName = "nix.mds.xyz" ; } NFS_KRB5 {         PrincipalName = "nfs/nfs01.nix.mds.xyz(a)NIX.MDS.XYZ" ;         KeytabPath = /etc/krb5.keytab ;         Active_krb5 = YES ; } NFS_Core_Param {         Bind_addr=192.168.0.100;         NFS_Port=2049;         MNT_Port=20048;         NLM_Port=38468;         Rquota_Port=4501; } %include "/etc/ganesha/export.conf" /etc/ganesha/export.conf EXPORT {         Export_Id = 1 ;         Path = "/n";         FSAL {                 name = GLUSTER;                 hostname = "nfs01.nix.mds.xyz";                 volume = "gv01";                 # UID_GID_Mapping = NFSv4_ID_Mapping;         }         Access_type = RW;         Squash = No_root_squash;         Disable_ACL = FALSE;         Pseudo = "/n";         Protocols = "3", "4";         Transports = "UDP", "TCP" ;         SecType = "sys","krb5","krb5i","krb5p";     # "sys","krb5","krb5i","krb5p"; } [root@nfs01 glusterfs]# -- Thx, TK.
