Common administrator’s rights. The individuals responsible for
administration of a farm should have administrative rights over each server in
the farm. When you log into a Citrix server console or ICA session and run
Published Application Manager, you administer applications under the context
of your current Windows NT user name. Although you can view the
applications on other servers in the farm without having administrative rights
over those servers, you cannot publish or edit applications on those servers.
For this reason, users who must run Published Application Manager to publish
applications should make sure they have administrative privileges on each
server in the farm.
u
Common base of user accounts. Server farms can include servers, and
therefore users, from multiple domains. All ICA Client users must belong to a
group of users common to all involved domains. Published Application
Manager draws a common user account base from the intersection of the trust
relationships of all affected Windows NT domains. See “Trust Intersection”
below for more information on determining a common base of user accounts.
u
Physical Connection. Servers in a farm must be connected by some form of
network connection. Some possible network connections include LAN, WAN,
and dial-up asynchronous connections. Servers can be on different subnets if
an ICA Gateway is in place to connect them. ICA Gateways are administered
from Citrix Server Administration. See “Connecting Citrix Servers Across
Network Subnets” in Chapter 4, “Configuring MetaFrame” for more
information.

The way you group servers into server farms depends on having a common base
of user accounts among all involved Windows NT domains.
The common base of user accounts is determined by the intersection of the
underlying trust relationships among the domains. For example, a farm can
contain servers from:
A single domain named A The trust intersection of A is A. You can configure
published applications for all of A’s users. This
model works for a single server that is a member of a
Windows NT domain, multiple servers that are
members of a single Windows NT domain, as well as
a single server that is a member of a Windows NT
workgroup.
