Sun Java System Calendar Server 6.3 WCAP Developer's Guide

Authentication

Do internal authentication using either the default LDAP authentication, or your own CSAPI plug-in to link to an existing user authentication method. For more information on CSAPI authentication and proxy authentication APIs, see Sun Java System Calendar Server 6.3 WCAP Developer’s Guide.

If the user fails to authenticate correctly, the login window reappears with an error noting a failure to log in.
