[Bug 938581] Re: rpc.svcgssd ERROR: prepare_krb5_rfc_cfx_buffer: not implemented

[Taylan]

We have upgraded some of our clients to 12.04 and the kerberized mounts
from centos-Machines won't work anymore with the same log messages:

Jul 17 14:08:41 xxxx rpc.svcgssd[3364]: ERROR: prepare_krb5_rfc_cfx_buffer: not implemented 
Jul 17 14:08:41 xxxx rpc.svcgssd[3364]: ERROR: failed serializing krb5 context for kernel 
Jul 17 14:08:41 xxxx rpc.svcgssd[3364]: WARNING: handle_nullreq: serialize_context_for_kernel failed 
Jul 17 14:08:41 xxxx rpc.svcgssd[3364]: ERROR: prepare_krb5_rfc_cfx_buffer: not implemented 
Jul 17 14:08:41 xxxx rpc.svcgssd[3364]: ERROR: failed serializing krb5 context for kernel 
Jul 17 14:08:41 xxxx rpc.svcgssd[3364]: WARNING: handle_nullreq: serialize_context_for_kernel failed 

The kerberized mounts from Solaris-Cluster are working.

The problem is, I can't set the encryption type to DES, bcs our Domain-
Controllers won't support them (by default) and even if they to, I
should create a new keytab for them and distribute it...
