Sharepoint 2016 déploiement

Question

Hi All

 

I have a a déploement of  new farm sharepoint 2016  , but i have some difficulties, because the forest of the farm is différent from the forest of users that should acces to the farm, i have a forest of shared application where the  sharepoint 2016 farm will install, and others forests wher the users of the farm reside, there is a two way  trust relation between the forests, how i can authenticate users froms other forests, and how i can synchronise all the users in the user profile service. Any help please.

 

Thanks.
