* The authentication policy document can contain multiple auth_source

* sources or for the same authentication source but specifying a different

*
* <?xml version="1.0" encoding="ISO-8859-1"?>

* <auth_source>
* <realm>Corp_eDirTree</realm>
* <mechanism>Krb5Authenticate</mechanism>

* <auth_source>
* <realm>Corp_eDirTree</realm>
* <mechanism>PwdAuthenticate</mechanism>
* <mechanism_info></mechanism_info>
* </auth_source>
* </auth_policy>
*
* This authentication policy would tell the CASA client that it can
* authenticate to the CASA Authentication Token Service using
* credentials for the Corp_eDirTree and utilizing either the
* Krb5 authentication mechanism or the Pwd authentication mechanism.
* The Krb5 authentication mechanism context data specifies the
* name of the Kerberos service principal.
