see the  '(rw'  in those lines?  That indicates read and write privs, 
but not execute.

I'm not an nfs guru, so I might be wrong.  this post suggests that I am 
wrong:

http://jackhammer.org/node/7

SInce IPA is managing the IDs, they should be in sync across the NFS and 
autmounted client machines, but there might be something not right in 
the setup.  if the IPA server isn't managing the machine that serves as 
your NFS server, then the IDs are certainly going to be out of sync.
