I've successfully integrated SiteMinder with Spring Security. However, Spring Security's logout URL doesn't apply to SiteMinder.
Spring Security
<logout delete-cookies="JSESSIONID" logout-success-url="/" invalidate-session="true" />
Spring Security Logout URL
<a href="<c:url value="j_spring_security_logout" />" > Logout</a>
Any suggestions which URL to use for SiteMinder/PreAuthentication?
