You said this works with the existing security. Does it work with LDAP? Does it work with Active Directory?

We take mashup security EXTREMELY SERIOUSLY. JackBe has mashup implementations with the Defense Intelligence Agency as well as the Defense Information System Agency (DISA). So we have advanced features like certificates and encryption as well. And we are PL3 certified by the DoD. It's safe to say that we are the most secure mashup solution available.
