Multiple Server Configuration Entries
The following example, also typical of openLDAP, defines three directory server entries in
addition to the default entry. The default entry includes all attributes common to the servers; it
omits the host name and indicates a priority of 0, because this entry does not describe an actual
directory server. The other entries include the host names and relative usage priorities of the
servers that provide access to the external directory. In this case (and in many corporate directory
configurations), all servers provide access to the same directory data.

Note that this example explicitly defines a default server entry. This feature indicates that the
servers have been configured in NCI. The strategy of defining most attributes only once is common
to NCI and HPDM, but the implementations are different:
• In NCI, you can specify most parameters in the default entry and then provide minimal
parameters when you configure a specific server or domain, as in the example above.
• In HPDM, you propagate values of parameters such as the port, version, search user DN,
and encryption option by defining them for one server and then using the Add Like button
to define additional servers with the same parameter values. In addition, parameters that
you specify in the Common Parameters area in the Add Directory Server dialog automatically
apply to all other servers you define.
NOTE: If you define a server with minimal parameters in NCI and then use HPDM to display
a list of all configured servers, any attributes you omitted for an individual server are left blank.
That is, HPDM does not display the default values inherited by the specific server. If you want
HPDM to display all attributes for a server you configure using NCI, then you must specify all
attributes in the CREATE SERVER command.
One Configuration Entry Mapping to Multiple Servers
The following example, also reflecting configuration in NCI, includes only one directory server
entry in addition to the default entry. The default entry includes most attributes, as in the previous
example. The other entry appears to represent a specific directory server, but the host name is
really a DNS name that maps to multiple servers. A configuration like this one provides superior
load balancing and fault tolerance, because every connection to the DNS address is routed to a
