Description of problem:

SELinux is preventing /usr/bin/iceauth from read access on the lnk_file squish.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that iceauth should be allowed read access on the squish lnk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep iceauth /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

We allow it in Fedora16/17. Backporting to F15.

Comment 2 Miroslav Grepl 2012-02-20 15:42:28 UTC
Actually, 
you need to turn on the use_nfs_home_dirs boolean

$ setsebool -P use_nfs_home_dirs 1
