Ah, yes, when I was reading the source, it seemed like a good place to start writing a custom module. I do not have time to do this in the current schedule, but will do it for the next cycle. Thanks Anil. Note: One thing that helped when using this verifier and the BaseCertLoginModule was changing the SubjectDNMapping to the obscure SubjectCNMapping in the JBossSecurityMgrRealm in server.xml. In this way I only had to load the CN instead of the long, odious DN into the user-roles.properties file. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4224702#...
