What is forest wide authentication?
Forest-wide Authentication – This is the default authentication setting for forest trusts. Users in remote forest will be automatically allow to authenticate local forest resources. In here it doesn’t means any user in remote forest can access any resources.
How does authentication work in forest trust?
Authentication requests follow these trust paths, so accounts from any domain in the forest can be authenticated by any other domain in the forest. With a single sign in process, accounts with the proper permissions can access resources in any domain in the forest.
How do I enable selective authentication in forest trust?
For each outgoing forest trust, right-click the trust item and select “Properties”. Select the “Authentication” tab. Select the “Selective Authentication” option. (It may be necessary to configure the “Allowed to Authenticate” permission on resources in the trusting domain.)
What type of trust should be used to enable users between two forests to authenticate and access resources within the other forest?
Explicit trusts are also used to enable authenticate across forests. When a forest trust is created, a transitive trust is created between the forest root domains in both forests. This allows all the members in the forest to exchange authentication information with the other forest.
Will creating forest trust?

Is SID filtering enabled by default?
SID Filtering and AD Migration For a newly set up trust between two domains or two forests, the SID Filtering is activated by default. The filter removes all foreign SIDs from the user’s Access Token while accessing a resource via a trust in a trusting domain.
What is the disadvantage of configuring selective authentication for a trust?
What is the disadvantage of configuring selective authentication for a trust? The administrative overhead involved to configure and maintain user access to resources. When all users in the trusted domain need to authenticate against the trusting domain.
What is the difference between external trust and Forest trust?
Selective authentication in a forest trust enables you to limit which users and groups from the trusted domain are able to authenticate. An external trust is a trust between domains in different forests. External trusts are not transitive.
What is a good practice to follow with forest trust?
Here are some best practices on managing trusts to make authentication available and management of your AD infrastructure much easier. Use shortcut trusts to eliminate delays. Delays creep up when your Active Directory forest has lots of trees in it containing multiple child domains.
How do I grant to authenticate?
Right-click on the OU, select Properties, then Security, then click on “Advanced”. Click “Add”, or select an existing account and click “Edit”. Enable the permission “Allowed to authenticate”.
