Subject: gssd mounts not working

Hello,
We are having problems with our gssd nfs mounts. I will explain our
situation.

Our clients are running SLED 11 SP1.
Our server is a Netapp filer with Ontap 7.3.3P4.

We provide NFS exported directory's with krb5 security.

Our KDC is a Windows 2003 and 2008 Active Directory.

If we use nfs-client-1.2.1-8.1 everything works as expected.

But if we upgrade to (any) newer client, all gssd mounts fail. Now there
is a bugreport on Novell Bugzilla about this :
https://bugzilla.novell.com/show_bug.cgi?id=614293#c7

Apperantly if the nfs client is compiled with --disable-tirpc , the
ticket size from the AD is to big ?

On our Redhat server we do not have these problems. There we are running
: nfs-utils-1.2.2-7

Is there an explanation for these problems ? How can i find out if a
client has been compiled with specific options. There is no nfs devel
package for suse.

Greetings .. Richard Smits

Yes this problem was fixed in libitrpc with:

Good question... I don't think there is way to was to tell how each
binary has been compiled... but doing a ldd `which rpc.gssd` will show
which shared libraries will be used.. If libtirpc.so.1 does not show up
in that list the you know the rpc.gssd was compile with --disable-tirpc

steved.
