Ok, first of all, thanks for the quick answer. I am in fact already one step further. I implemented an authenticationprovider and an authentication service. The provider basically ignores all authentication checks as a first step and the service generates a user with predefined roles from the request. So far so good, the jasper server now accepts the login, also it writes that the user is authenticated but the forward to the main page still does not work, it still is stuck in the login page. The affect server log says: WARN LoggerListener,http-8080-Processor25:55 - Authentication event InteractiveAuthenticationSuccessEvent: lexow; details: org.acegisecurity.ui.WebAuthenticationDetails@fffc7f0c: RemoteIpAddress: 127.0.0.1; SessionId: 9C0EB6BDE4FB115FFE87811F5BADD8BA 16:30:05,238 WARN UserAuthorityServiceImpl,http-8080-Processor25:500 - Added following external roles to: lexow ROLE_ANONYMOUS ROLE_USER 16:30:05,247 WARN UserAuthorityServiceImpl,http-8080-Processor25:536 - Updated user: lexow. Roles are now: ROLE_USER ROLE_ANONYMOUS ROLE_ADMINISTRATOR 16:30:05,292 WARN UserAuthorityServiceImpl,http-8080-Processor25:542 - Updated user: lexow. Roles are now: ROLE_USER ROLE_ANONYMOUS ROLE_ADMINISTRATOR Well as it seems the server accepts the authentication for the foreign datasources now, but does not do anything afterwards. Attached are the two source files, the authentication provider and the user DetailService: (packed zip file due to upload restrictions) [file name=provider.zip size=3041]http://www.jasperforge.org/components/com_joomlaboard/uploaded/files/provider.zip[/file] Post edited by: senton9999, at: 2006/08/30 14:38
