tomcat, SingleSignOn and session persistance

[olkin <ol...@gmail.com>]

 Hi all!
I've just found that SingleSignOn valve invalidates session when passivate
event came (e.g. tomcat is shuting down). So I need to relogin every time
when tomcat restarts. But this is not sutable for me because my web
application configures remote host (where tomcat is installed) and restarts
it after configuration.

Do you know any way how to use SingleSignOn and session persistance
together?

I use tomcat 5.5.20; to authenticate users I use form-based authentication
and JAASRealm.
