SAML Authentication from iOS Edge Client

I was wondering whether anyone has had any success using SAML authentication for iOS Edge Client access?

I am using iOS Edge Client 2.0.9. The release notes for 2.0.3 announced that SAML authentication had been added for SP-initiated connections using the Web Logon mode.

I am able to trigger SAML authentication within the APM policy when the Edge Client connects, but once successfully authenticated against the IdP via the web-logon, an assertion fails to arrive.

If anyone has been able to get this working it would at least help me to know where to focus my debugging efforts.

Thanks,

Barny
