I have a 3-tier SharePoint 2013 on-premise deployed. We have 4 domains with a 2-way trust across all. The SharePoint Server is setup in ie: Domain1 and is working perfectly using Domain1 credentials. Have added the other 3 domains to People Picker via PowerShell.
Now, Domain1, Domain2, and Domain3 were able to access the SharePoint using their respective credentials but Domain4 is not. I am being prompted for credentials for 3 times but nothing happens after, as in nothing... no errors or prompts whatsoever.
I am able to populate the credentials in all domains through UPSA using the created service accounts in each domains.
Hope you can help me with my dilemma. Many thanks.
