Identity Management (IPA) and NFSv4 question

Hey all.

I'm running identity mangement (IPA) server on rhel 6.2.

I've been trying to setup a kerberos integrated NFS server on rhel 5.7 with the clients running rhel 6.2.

I've been following the identity management beta steps for RHEL 5.8 for setting up the server, most important part is specifying crypto type to des-cbc-crc and to allow a lower crypto in /etc/krb5.conf. I get the keytab setup but am unable to mount a share. Anyone know if i'm barking up the wrong tree and this is impossible?

Regards

Johnny
