Hi, I need some help on SSL client authentication. If a user has digital certificate installed on his/her machine, we like to authenticate the user using digital certificate, otherwise using username/password. When I set clientAuth="true" in server.xml, open IE to the server URL (https), IE popup a window asking for the client certificate even though there is no certificate found in client machine. 1. how to ask client browser(IE) to ignore digital certificate if not found? 2. on server, how to get the client certificate for verification? java API? Thank for help. Dave
