Kerberised NFSv4 share error - mount.nfs4: access denied by server while mounting + Rocky Linux 8.8

[vishal1995]

Hi all,

Good evening,

We are facing a mounting issue in the Rocky Linux-based workstation for one of the Kerberised NFSv4 exports.

Below are the details of the Client system and TrueNAS storage -

Client System -

OS - Rocky Linux 8.8
Authentication Method - AD + SSSD + Kerberised NFS home (Centralized Home)

Mount Parameter -

<hostname>:/mnt/datapool01/systems /mnt/test nfs4 rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=krb5 0 0

We are using the static mount method for it and putting the above value in "/etc/fstab"

TrueNAS Storage -

OS - TrueNAS Core 13.0-U4


export parameters -
V4: / -sec=krb5:krb5i:krb5p
/mnt/datapool01/systems -alldirs -maproot="root":"Domain Name\\Domain Group Name" -sec=sys:krb5i



Error -

mount.nfs4: access denied by server while mounting <hostname>:/mnt/datapool01/systems


I would appreciate any suggestions or recommendations.


Regards
