Problem getting SSO to Sharepoint 2013 to work after DUO push authentication.
Hi we are using Duo security integrated with F5 APM version 12 sp1. I need to publish a Sharepoint 2013 site using Duo Security with push as the two factor solution. I started out by deploying the latest Iapp for Sharepoint 2013 and then replaced the AD authentication in the VPE with Radius Authentication using Duo, the VPE policy is :-
In the variable assign i am using the following session variables:-
The SSO looks like this:-
At the moment the two factor works and login is accepted using only username and domain password followed by acceptance of the push message from Duo, we then receive a 401 and then a ntlm authentication prompt because the variable assign together with SSO are not configured as they should be.
Any tips or advice appreciated.
