NFS4+AIX 5.3+EMC Celerra. How do you get it to work?

In our environment, we have deployed VAS 3.1x and 3.2x, and it tends to be quite stable.

The architects feel that, since it is a KRB5 implementation we should be able to use it for NFS4 for krb5i against our EMC Celerra NAS.

I have looked at the Sol 10 configuration, and have drawn as much inference from there as I can, but still cannot get it to work.

Has anyone successfully done any or all of the below, and if so, would you be willing to share your configuration with me?

Thanks.

1) use VAS with AIX KRB config to mount NFS4 from another AIX/VAS host
2)use AIX KRB for NFS4 to mount EMC NAS Celerra
3) use VAS with AIX KRB config to mount NFS4 from EMC NAS Celerra
