Before you start the installation process for DHCP, review the following:
Java Management Console is required for creation of the DHCP Service object. For details see Section 1.4.2, eDirectory Objects for DHCP.
IMPORTANT:Do not install any of the following service combinations on the same server as OES DHCP. Although not all of the combinations cause pattern conflict warnings, OpenText does not support any of the combinations shown.
Xen Virtual Machine Host Server
If you are installing OES DHCP Server on an eDirectory tree for the first time, you require the following rights on the Server, Locator, and Group containers at the eDirectory level before you start the DHCP installation.
Create permission at the entry level of the container for the following:
DHCP Server Object Container
Locator Object Container (dhcpLocator)
Group Object Container (DHCPGroup)
DHCP Proxy User Object Container
If you are installing DHCP Server on an eDirectory tree, make sure that you have the following permissions:
Create permissions at the entry level of the container for the following objects:
DHCP Server Object Container
DHCP Proxy User Object Container
Read and Write permissions for the existing objects at attribute level of the objects.
Locator Object Container (dhcpLocator)
Group Object Container (DHCPGroup)
To retrieve the existing Locator and Group objects context, specify the following rights:
Read and compare rights at the attribute level and browse rights at the entry level of the container where DHCP Locator and Group objects are present.

Create the dhcpLocator object and the DHCPGroup object at the top of the eDirectory tree.
Replicate the eDirectory tree on the server running DHCP so that the search for the objects is fast.
NOTE:In the eDirectory tree, multiple copies of dhcpLocator object and the DHCPGroup object can exist. If the dhcpLocator and DHCPGroup objects already exist, then Read permissions for the DHCPGroup object and Write permissions for the dhcpLocator object are required.
While installing the DHCP server on every node, it is recommended that you mention the same proxy user in the OES Credential Store. This will avoid creation and maintenance of multiple proxy users in the Directory.
