Kerberos usage
You must initialize Kerberos before you can use the command line for Kerberos authentication.
Run the following command to initialize Kerberos:
kinit <kerberos_principlename>@<realm_name>To
use Kerberos for authentication you must specify the -m option
with the GSSAPI parameter on the idsldapadd and idsldapsearch commands.
For example: idsldapsearch-V 3 -m GSSAPI -b <"cn=us"> objectclass=*
