There is a custom Auth mode I think that allows you to use ad for Auth and LDAP 
for identity. You'd could do what you wanted but you'd need another LDAP 
instance that mapped the ad usernames to the UID that is only used by SMB. 

Hack yes.

Subject: Re: [gpfsug-discuss] Exporting remote GPFS mounts on a non-ces SMB 
share

We have many current usernames from LDAP that do not exactly match with the 
usernames from AD.
Unfortunately, i guess CES SMB will need us to use either AD or LDAP or use the 
same usernames in both AD and LDAP.
I have been looking for a solution where could map the different usernames from 
LDAP and AD but have not found a solution. So exploring ways to do this from 
RHEL SMB.
I would appreciate if you have any solution to this issue.

As of now we use LDAP uids/gids and SSH keys for authentication to the HPC 
cluster.
We want to use CES SMB to export the same mounts which have LDAP 
usernames/uids/gids however because of different usernames in AD - it has 
become a challenge.
Even if we do find a solution to this, i want to be able to use AD 
authentication for SMB and ssh key authentication for NFS.

The above are the reasons we are just using CES with NFS and user defined 
authentication for users to have access with login through ssh keys.

Lohit

That would not be supported

You shouldn't publish a remote mount Protocol cluster , and then connect a 
native client to that cluster and create a non CES protocol export
if you are going to use a Protocol cluster that's how you present your 
protocols.
otherwise don't set up the remote mount cluster.

Why are you trying to publish a non HA RHEL SMB share instead of using the HA 
CES protocols?

Thank you Andrew.

However, we are not using SMB from the CES cluster but instead running a Redhat 
based SMB on a GPFS client of the CES cluster and exporting it from the GPFS 
client.
Is the above supported, and not known to cause any issues?
