Oracle Virtual Directory (OVD) : LDAP Adapters

With Oracle Virtual Directory a LDAP adapter can be created which is mapped to either user container ("cn=users,dc=example,dc=com") or root value in LDAP server. It can also be mapped to the tree of the server (dc=example,dc=com). If two different LDAP adapters are created within OVD a user can be searched from both the directories or from a single directory based on the Mapped name space in the OVD.
Below is the use case scenarios depicting the same:
Create an Adapter with OID/OUD using remote base as “” and mapped name space to “dc=eus,dc=oracle,dc=com”. It can also be mapped to either tree (dc=oracle,dc=com) or user container (cn=Users,dc=oracle,dc=com).If we have to search the root values also from OID/OUD then map it to "".



 Now from the adapter browser even cn=”changelog” can be seen which doesn’t come under “dc=us,dc=oracle,dc=com” tree in OUD.


Create another adapter for Active directory mapping it to remote base as “dc=dev,dc=oracle,dc=com”.



Now mapping is as below:
OUD/OID:
Remote base: “”
Mapped Name Space: dc=eus,dc=oracle,dc=com
AD:
Remote Base: “dc=dev,dc=oracle,dc=com”
Mapped Name Space: dc=eus1,dc=oracle,dc=com
Now below use cases can be completed using ldapsearch through OVD.

Usecase:1 à Searching a user in both the directories.
If Ldapsearch is run against “dc=oracle,dc=com” then OVD will search the user in both the directories.
Searching an OUD user:

Now searching the above user “uid=user.0” through OVD.


Searching an AD user:


Searching the above user “cn=oam” using ldapserach.


Usecase:2 Searching a user in OUD.
A user can be searched in only OUD using mapped name space “dc=eus,dc=oracle,dc=com” while searching through OVD.


Usecase:3 Searching a user in AD.
A user can be searched in AD using the name space “dc=eus1,dc=oracle,dc=com” while searching through OVD.

Oracle Traffic Director (OTD) configuration

Download the OTD software and install it on a server by running runInstaller command from <Binaries>/Disk1. Preferred is to configure the OTD as root user because when the administration server is configured as root, then Oracle Traffic Director starts the keepalived daemon automatically when you start instances that are part of a failover group, and stops the daemon when you stop the instances. Set Oracle_Home as the new Installed OTD Home. Run below command to configure the Admin server: <OTD_HOME>/otd/bin/tadm configure-server --port=8989 --user=admin --server-user=root --instance- home= <OTD_HOME> /otd/instance_name/otd_instance1 This command will ask for admin password and will create the admin server. Run Below command to start the admin server: <OTD_HOME> /otd/instance_name/otd_instance1/admin-server/bin/startserv Login to the OTD console on http://<host>:8989 as admin user.  Click New configuration: Click Next and create ne...
