Dear Scientific Linux CERN 5 and 6 users.

System update on Thursday, 21st of March 2013 will include following
Kerberos related changes:

- cern-config-keytab will be obsoleted and replaced by cern-get-keytab

- kerberos configuration (/etc/krb5.conf) will be adjusted to point to
  kerberos key distribution center (KDC) for the given network:

   atlasvdc.cern.ch for ATLAS network
   cmsvdc.cern.ch for CMS network
   tndc.cern.ch for TECHNICAL NETWORK

  for GENERAL PURPOSE NETWORK (or systems on a network not belonging
  to any of above three):

   cerndc.cern.ch (this is the current setup)

If you would like to test the change on your system, please run
as root following commands:

# yum --enablerepo=slc*-testing clean all
# yum --enablerepo=slc*-testing install lcm-profile arc cern-get-keytab cern-config-keytab
