When to create a realm trust

A realm trust can be established between any non-Windows Kerberos V5 realm and a Windows Server 2003 domain. This trust relationship allows cross-platform interoperability with security services based on other Kerberos V5 versions such as UNIX and MIT implementations. Realm trusts can switch from nontransitive to transitive and back. Realm trusts can also be either one-way or two-way.
