ZSH not working with SMB/CIFS file share

Hello

Summary:

We are using Active Directory and pam_mount

pam_mount.conf.xml:

<?xml version="1.0" encoding="utf-8" ?>
<pam_mount>
<debug enable="1" />
<volume
 fstype="cifs"
      sgrp="domain users"
      server="10.150.102.35"
      path="WSOEDC/%(USER)"
      mountpoint="/home/WSOEDC/%(USER)"
      options="sec=ntlmsspi,nounix,workgroup=WSOEDC,file_mode=0700,dir_mode=0700,vers=2.1,noserverino"
      ssh="0"
/>
<mntoptions allow="nosuid,nodev,loop,encryption,fsck,nonempty,allow_root,allow_other" />
<mntoptions require="nosuid,nodev,noserverino" />
<logout wait="0" hup="no" term="no" kill="no" />
<mkmountpoint enable="1" remove="true" />
</pam_mount>
 

When a user attempts to access zsh:

ismith@cs-spock2:~$ zsh
ismith@cs-spock2 ~ % test
ismith@cs-spock2 ~ % history
    1  test
ismith@cs-spock2 ~ % ls
 hello.txt  'nvme_nas write speed.txt'   old_dot   snap   ssl_setup   ubuntu-16.04.5-desktop-amd64.iso
ismith@cs-spock2 ~ % exit
zsh: locking failed for /home/WSOEDC/ismith/.zsh_history: operation not supported
 

The home folder is mounted at /home/WSOEDC/<user> and the permissions are:

ismith@cs-spock2:~$ ls -lhart
-rwx------ 1 ismith domain users   14 Oct 12 15:40  hello.txt
drwx------ 2 ismith domain users    0 Oct 12 15:48  .local
drwxr-xr-x 5 root   root         4.0K Oct 12 16:02  ..
-rwx------ 1 ismith domain users  704 Oct 12 16:05  .viminfo
-rwx------ 1 ismith domain users    0 Oct 14 15:42  .zsh_history
-rwx------ 1 ismith domain users 5.6K Oct 14 16:22  .bash_history
-rwx------ 1 ismith domain users 1.4K Oct 15 10:10  .zshrc
-rwx------ 1 ismith domain users  160 Oct 15 10:42  .Xauthority
drwx------ 2 ismith domain users    0 Oct 15 11:11  .
-rwx------ 1 ismith domain users  49K Oct 15 11:11  .zcompdump
 

This also happens when using 'file_mode=0755,dir_mode=0755' as well for the mount.

Unsure where else to go from here, I also know NFS permissions are not working properly on TrueNAS Scale yet so only other thing I can think of.
