Hi all, and thanks for reading me ... I have read a lot of posts about client authentication with tomcat and i """pray""" to somebody for giving a final solution to this problem in Tomcat 4.0 b7. I mean, could somebody describe all the process (commands used) of the certificates generation (keytool + openssl), conversion and instalation of this certificates in the tomcat keystore and IE ?
