I have searched the interwebz, but haven't found anything specific. Problems are either different or answers are 5 years old.
I've got a SharePoint 2016 on premise farm. 2 Web applications: companyA and companyB. Users need to be synchronized from 2 domains: companyADomain and companyBDomain.
I have set up 2 separate web applications to host My Sites A and B. Set up 2 UPS applications: First one: synchronizes users from companyADomain, MySites are configured to redirect users to My Site A. Second one: synchronizes users from companyBDomain, MySites are configured to redirect users to My Site B.
Let's say I have 2 test users. Test User A (from A domain) and Test User B (from B domain). UPS syncs users in a proper way - User A ends up in UPS A and User B ends up in UPS B.
The problem: on either of the web applications and by either of the users, when they click on "About Me" on the ribbon, they are both redirected to My Site A. Which is correct for User A, but I want user B to be redirected to My Site B.
Does anyone have any clues what I am doing wrong?
