Description Jan Stancek 2011-03-03 15:53:36 UTC 
Description of problem:
Can not mount nfs, with udp transport and kerberos security (krb5/krb5i/krb5p), for nfs versions 2 and 3.

Version-Release number of selected component (if applicable):
Server
------
Release: Red Hat Enterprise Linux Server release 5.6 (Tikanga)
Kernel: 2.6.18-238.el5
nfs-utils-1.0.9-50.el5, nfs-utils-lib-1.0.8-7.6.el5

Client
------
Release: Red Hat Enterprise Linux Server release 5.6 (Tikanga)
Kernel: 2.6.18-238.el5
nfs-utils-1.0.9-50.el5, nfs-utils-lib-1.0.8-7.6.el5

How reproducible: 100%

Steps to Reproduce:
1. On server setup share as: 
/mnt/testarea *(fsid=0,sec=krb5:krb5i:krb5p:sys,rw,sync,no_root_squash)
2. Setup kerberos on server and client:
3. Try to mount:
mount -t nfs -o nfsvers=3,udp,sec=krb5 server:/mnt/testarea /mnt/test

Actual results:
mount.nfs: Permission denied

Expected results:
Share will mount

Additional info:
If tcp is used instead of udp, all work as expected.
If RHEL6 is used as Client, mount udp+krb5 works as expected.
