HP CIFS Server 3.0f Administrator's Guide verison A.02.03

Shortcut trusts can be established explicitly between Windows 2000/2003 domains to ensure HP CIFS
Servers recognized forest configurations where necessary.
Transitive trusts, in which domain A trusts domain B which trusts domain C thereby domain A trusts domain
C, are not respected by HP CIFS Servers.
