Global Directory Conguration
ILS
An Internet Locator Server (ILS) server is a directory that stores names, aliases, Email
addresses, and IP addresses of registered users. ILS works differently in the replication of
directory information but yields the same result of all networked Global Directories containing the
same directory information.
Networked directories will report to one ILS server. The entries from all networked Global
Directories will post their directory entries to the ILS server. Each Global Directory will then pull
the cumulative new entries from the ILS server. Hence, all address books will contain the same
directory entries.
Figure 3.5 ILS pictorial representation
ILS Server on Site Server 3.0 or Site Service ILS Service on Windows 2000 Server is supported
by Global Management System 2.X or higher. When conguring Global Management System to
communicate with either of these servers, keep in mind that Site Server 3.0 is default to port 389
while Site Server ILS (Win2000) is default to port 1002.
NOTE
The ILS replication feature will not replicate any H.320 entries. Only H.323 entries will be
replicated into the Global Directory.
NOTE
ILS may stop replicating entries into the Global Directory address book. If this occurs, reboot
the ILS server.
