[Pki-devel] [PATCH] 107 Added proxy realm.

CMS engine is a singleton and it's used by PKI realm to authenticate users accessing the subsystem. Since a Tomcat instance may contain multiple subsystems, each having separate realm, the PKI JAR files need to be moved into WEB-INF/lib so that they will run inside separate class loaders. Note that Tomcat requires that the JAR files be copied into this folder, they cannot be linked. Tomcat also requires that the authenticator and realm classes be available in common/lib. To address this a new package pki-tomcat.jar has been added. The package contains the authenticator and a proxy realm. When the subsystems start running, they will register their own realms into the proxy realms such that the authentications will be forwarded to the appropriate subsystems. Ticket #89 -- Endi S. Dewata
