MFA - Modern Authentication Skype for Business with VVX Phones

We have a customer who want to enable MFA authentication within their Skype for Business environment. User only user MFA when being outside of the office network.

 

Internally they are using some VVX501 phones, but when Modern Authentication is enabled, users are not able to sign in, as the phones cannot get a token from the ADFS server.

 

So the question is: Is Modern Authentication supported with Firmware 5.5.1.1? And if it is, is there some guidance how to set it up?

Thanks

Re: MFA - Modern Authentication Skype for Business with VVX Phones

Hello Tim Wijnands,

welcome to the Polycom Community.

As far as I know Modern Auth is not to be recommended to be enabled for a On Premise Server. This is an information we received from Microsoft for another case.


Is you issue for Pin and Extension or for Single Sign in?

Re: MFA - Modern Authentication Skype for Business with VVX Phones

For both option it is not working we are getting the following error on the ADFS sever:

 

Exception details:

Microsoft.IdentityServer.RequestFailedException: MSIS7065: There are no registered protocol handlers on path /adfs/oauth2/authorize/common/UserRealm/roy.vandongen@securelink.nl to process the incoming request.

   at Microsoft.IdentityServer.Web.PassiveProtocolListener.OnGetContext(WrappedHttpListenerContext context)

 

Also i found the following article:

https://support.microsoft.com/en-us/help/3211755/new-features-in-the-firmware-update-for-polycom-vvx... 

 

So should Modern Authentication work?
