This chapter contains information specific to multiple domains. If you do not store and group
information in multiple domains, you can skip this chapter.

Domain Term Definitions
The following section defines common multiple domain terms.
Multiple Domains
Supported multiple domains refer to domains in an ADS forest. Domains from different forests
are not supported.
Local Domains
Local domain is the first domain configured using the LDAP-UX setup tool after choosing
Windows 2000 or 2003 ADS as your directory server. The local domain is also the only domain
configured if you select a single domain to store your POSIX information. When LDAP-UX
retrieves POSIX information, the local domain is always the first domain searched. If the entry
is found in the local domain, the search stops. Therefore, the local domain is the primary domain
where frequently accessed information should be stored. Its profile configuration is
/etc/opt/ldapux/ldapux_profile.bin.
Remote Domains
Remote Domains are all domains in the forest other than the local domain. When multiple domain
support is selected during setup, you are guided to configure profiles for remote domains. When
LDAP-UX cannot find data from the local domain, remote domains are searched.
Global Catalog Server
Global Catalog Server (GCS) is the domain controller that hosts the global catalog for a forest.
The global catalog contains partial information for each domain. LDAP-UX utilizes this feature
to determine to which domain a queried data belongs. The root domain is the default GCS.
Retrieving Data from a Remote Domain
LDAP-UX can retrieve data from a remote domain using three methods:
• Remote Domain Configuration
This method allows you to configure a sequence in which LDAP-UX searched remote
domains. If you know in which domains your data resides, you can use setup to configure
