Subject Reposting: SSL Client authentication with standalone Tomcat
Date Tue, 26 Feb 2002 13:35:36 GMT
I repost this because it didn't show up on the list but
a subsequent posting already did:

This part should read:
The client browser scans his (previously imported) client certs
for a matching cert issuer/signer, fills / pops up a choice dialog
box to select a client cert from, 
and sends (?) the users selection back to the server.

This choice box was usually empty in MS IE. Read my previous
posting "Any success with Tomcat 4.0.2 and client
certificates in MS IE ?"
