12.4. Accessing Delegated Services

For both services and hosts, if a client has delegated authority, it can obtain a keytab for that principal on the local machine. For services, this has the format service/hostname@REALM. For hosts, the service is host.
With kinit, use the -k option to load a keytab and the -t option to specify the keytab.
For example, to access a host:
# kinit -kt /etc/krb5.keytab host/ipa.example.com@EXAMPLE.COM
To access a service:
# kinit -kt /etc/httpd/conf/krb5.keytab http/ipa.example.com@EXAMPLE.COM
