Hey Guy's,
Getting below message which in turn fails to list proper UID / GID on
NFSv4 mounts from within an unprivileged account. All files show up with
owner and group as nobody / nobody.
Wondering if anyone saw this and what the solution could be?
[root@client01 etc]# cat /etc/idmapd.conf|grep -v "#"| sed -e "/^$/d"
[General]
Verbosity = 7
Domain = nix.my.dom
[Mapping]
[Translation]
[Static]
[UMICH_SCHEMA]
LDAP_server = ldap-server.local.domain.edu
LDAP_base = dc=local,dc=domain,dc=edu
[root@client01 etc]#
Mount looks like this:
nfs-c01.nix.my.dom:/n/my.dom on /n/my.dom type nfs4
(rw,relatime,vers=4.0,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,port=0,timeo=10,retrans=2,sec=sys,clientaddr=192.168.0.236,local_lock=none,addr=192.168.0.80)
