Skype for Business Mobile App + Smart Card Required

I contacted Alex Simons yesterday from the IDAM PG to get some more clarity on the expected behavior in SfB when using CBA. My understanding of CBA was no username/password was required as CBA is Certificate Based Auth leveraging Oauth/ADAL. (at least that was my understanding when this feature was released and when i was initially researching CBA for SfB Mobile). If a u/p still has to be entered then thats hardly any different to the native NTLM/TLS-DSK support thats been part of SfB Mobile since Lync 2013, although NTLM/TLS-DSK is obviously not MFA. Admittedly the initial auth uses NTLM but subsequent auths use the cert issued from the provisioning service. CBA has been something customers have been asking for for a while. If its use is restricted just to MFA then in my opinion that kind of makes the feature redundant especially for enteprise customers who do not allow the use of credentials or NTLM over the internet.

I've been meaning to lab this for quite some time so i can observe the behavior. Sounds like that time is now MarkVale ! Sorry for hijacking your thread OP!
