GMS and MFA ( AAF )

I'm not able to get it working. Windows client / GroupWise Web are working without any problem.

I was in beta test of GroupWise 18.3, because of that I have very detailed how to document from Patti Brooks. System is configured with help of this document and videos which were posted on beta forum. Even that I'm not able to login into GMS as MFA enabled user. 

If I look on GroupWise POA logs, there is no attempt to authenticate. 

If I disable MFA on that user I can login into GMS via mobile email client without any problem.

Where is the catch ?

We have 24.2 GW system
