Setup VNX / Celerra and Kerberos

Hello

My client has a VNX 5500 Unified box, with NFS shares.

He would like to setup the Kerberos authentication to access the NFS shares, but I cannot manage to do this...

The fact is that:

- the KDC server is in fact the Windows 2003 Active Directory domain controller

- the clients which will mount the NFS share are Unix systems

I followed the documentation, but:

- when following procedure for a windows KDC - just setup the secure NFS service - nothing work

- when following the Unix procedure - using server_kerberos -kadmin, nothing work neither

My client has generated, on the KDC, principals for the machine, but I don't know what to do with this file. I tried to upload it to /.etc/krb5.keytable, but when I run server_kerberos -keytable, I still the 'default' principals.

And finally, whatever I try, the clients never get a Kerberos ticket (with klist), thus cannot connect to the share.

I see no error from the VNX box, neither the client.

How could I troobleshoot ?? does the control station need to have access to the KDC permanently ??

Thanks in advance
