Make sure that 'root' on the RIOS isn't in more than 8 groups (including
its default group in /etc/passwd).  

NFS servers before SunOS 4.0 fail if asked to authenticate a request from
a root login in more than 8 groups.  I'd guess that the Ultrix 3.0 server
has the same limitation.  Reducing the number of groups for root on our 
RIOS allowed us to mount both SunOS 3 and Ultrix 3.0 filesystems with no
problems.
