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.
