UID and GID Mapping with NFS Ganesha 3.5
by TomK
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]#
