I’m running:
SUSE Linux Enterprise Server 12 SP2 (x86_64)
Kernel:
4.4.90-92.45-default
When trying to mount a CIFS mount via the kernel:
[FONT=Courier New]# mount.cifs //111.1.111.111.111/fs/share /home/fsshare -o credentials=/etc/smbcredentials,sec=ntlm,vers=2.0
# mount.cifs //111.1.111.111.111/fs/share /home/fsshare -o credentials=/etc/smbcredentials,vers=2.0
# mount.cifs //111.1.111.111.111/fs/share /home/fsshare -o credentials=/etc/smbcredentials,sec=ntlm
[/FONT][/CODE]
All the above come back with the following error:
[CODE][FONT=Courier New]mount error(38): Function not implemented[/FONT][/CODE]
When doing it via smbmount:
[CODE][FONT=Courier New]# smbclient -U username -L fsserver01[/FONT][/CODE]
It comes back successful:

My fstab looks like:
[CODE][FONT=Courier New]# cat /etc/fstab

When mounting from the kernel it's really not using the /etc/samba/smb.conf file, so I don't see the need to post the config I have in here, but I have modified it to support SMB2 anyway.

Our Windows Fileshare is locked down to only do SMB2, but the support should be there with the kernel version we have running, along with SLES 12 SP2. Just doesn’t make sense.
Any help would be great =)
