Subject Re: Running unit test cases with Kerberos on
Date Thu, 17 Apr 2014 15:37:16 GMT
minikdc can be run from the commandline to do exactly that, as args you give dir where it will
create the krb5conf file, a list of principals to have, a keytab with all those princs will
be created in the dir, distribute the krb5.conf and the keytabfile to you clients. config
the cluents to pick up the krb5.conf, you are done. 

thx
