NFSv4 client shows user and group as nobody

• ONTAP 9
• NFSv4
• Linux

• When running the NFSv4 client command ls -l (or ll), the user and group show up erroneously as nobody as shown below:

Example NFSv3:

[root@nfs_SVM> mount_point]# ls -l test1
-rw-r--r--. 1 root root 0 Oct 18 12:34 test1

Example NFSv4:

[root@NFS_SVM> mount_point]# ls -l test1
-rw-r--r--. 1 nobody nobody 0 Oct 18 12:34 test1

• Client shows different ids compared to ONTAP

# getent passwd | egrep "username|id"
# getent group | egrep "groupname|id"

• ONTAP shows credentials in advanced privilege mode for local users and groups differing from client side details using the commands:

::*> vserver services name-service unix-user show -vserver SVM
::*> vserver services name-service unix-group show -vserver SVM

• ONTAP cannot resolve credentials from LDAP:

::*> vserver services name-service getxxbyyy getpwbyuid -node NODE-01 -vserver SVM -useriD 123 -show-source true
Error: command failed: Failed to resolve 123. Reason: Entry not found for "userid: 123".

::*> vserver services name-service getxxbyyy getgrbyname -node NODE-01 -vserver SVM -groupname example -show-source true
Error: command failed: Failed to resolve example. Reason: Entry not found for "groupname: example".

::*> vserver services name-service getxxbyyy getgrbygid -node NODE-01 -vserver SVM -groupiD 123 -show-source true
Error: command failed: Failed to resolve 123. Reason: Entry not found for "groupid: 123".
