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

[valleru at cbio.mskcc.org]

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.

Regards,
Lohit
