the resources in contoso.com.

B. Modify the Allowed to Authenticate permissions in adatum.com.

C. Enable SID quarantine on the trust between contoso.com and adatum.com.

Explanation:

*Accounts that require access to the customer Active Directory will be granted a special right called Allowed to Authenticate. This right is then applied to computer objects (Active

Directory domain controllers and AD RMS servers) within the customer Active Directory to which the account needs access.

For users in a trusted Windows Server 2008 or Windows Server 2003 domain or forest to be able to access resources in a trusting Windows

Server 2008 or Windows Server 2003 domain or forest where the trust authentication setting has been set to selective authentication, each user must be explicitly granted the Allowed to Authenticate permission on the security descriptor of the computer obj

ects (resource computers) that reside in the trusting domain or forest.
