Failed to login SharePoint 2019 site via UPN with a one-way trust domain
Dear Sirs,
We have two domains:
AAA.local
BBB.local
And there is a one-way trust relation: AAA trust BBB
Our SharePoint Server 2019 hosted on domain AAA.local,
- Users from both domains can sign in by: Domain\User
- Users form AAA can sign in by User Principal Name
- But users from BBB can not sign in by User Principal Name, why?
Can anyone help? Many thanks.
