Kerberos @Cern

Problem: login worked, but logging in from lxplus, with a valid krb tokens, did not, and the server kept asking for a password.

Solution:

install

ncm-afscl
ncm-krb4clt

1. in /etc/sysconfig/network
have the fully qualified name (e.g. pccmsto03.cern.ch)

2. in /etc/hosts
have both qualified and unqualified, qualified first, i.e.

137.138.99.57 pccmsto03.cern.ch pccmsto03
