Skype for Business 2015 with Seamless SSO and modern authentication

[Deleted]

Hi 

We have Azure AD Connect software that currently sync our AD password and users to Azure portal. We have installed Skype for business locally and we can log into this software by manually put in our AD username and password

We dont have local front end skype server and we only use skype for business for one -to - one collaboration 

Now we would need to improve this so users dont need to put in their username/password manually. I can see the option for seamless SSO and Modern authentication 

Basically from my reading, you would need to turn on SSO in Azure AD connect and this option will then be available in  Azure portal, adding 2 Azure URL into intranet zones and that is

I just wonder if anyone here actually implement this and can share some experience. Any chance of implementing this solution for some testers first before rolling out to the whole company?
