Windows Server 2003 Question:
How can you authenticate between forests?
Answer:
Four types of authentication are used across forests:
(1) Kerberos and NTLM network logon for remote access to a server in another forest;
(2) Kerberos and NTLM interactive logon for physical logon outside the user’s home forest;
(3) Kerberos delegation to N-tier application in another forest; and
(4) user principal name (UPN) credentials.
