Hello all,

It seems after doing some more serious googling I found that using a
system-account is problematic when using kerberized nfs4.

Like Anthony mentioned it would be nice to have a 'general' howto on how to
deal with this situation.

Apache trying to use a document root on a kerberized nfs4 share being a
very nice use case.

btw after I posted this I spend some more time on google and found this old
kb article on access.redhat.com com that deals with a kerberized nfs
document root for apache:
https://access.redhat.com/solutions/56581
I haven't tried it yet cause it feels a bit like a workaround to me and I
hoped to find a more elegant solution using ipa,

Cheers
Rob Verduijn
