with tomcat there's also a different approach to this problem using the 
SSOValve (org.liland.tomcat.valve.sso.SingleSignOn). however, in order 
to use this valve, the webapps need to let tomcat handle the 
authentication (see 
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/realm-howto.html or 
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/realm-howto.html).
depending on your webapps this kind of setup may be anything from 
"simply a matter of configuration" to impossible.
