Symptoms

On :  Application Server 10g, i.e., 10.1.3.5.0.

Trying to set up Identity Management to use Oracle Internet Directory (OID) for authentication using Oracle Enterprise Manager (OEM) Application Server Control (ASC).

Clicking on the Home container, then Administration tab, then Identity Management.  After entering the required information, getting error:

An error occurred while attempting to associate this instance with the specified Oracle Internet Directory. The security provider will NOT be changed for any application. Please ensure that the OID instance is indeed up and that the connect information provided is correct before retrying.
JAZN configuration failed: unable to create a JAZN entity in the directory.
[LDAP: error code 20 - Attribute Or Value Exists]

Tested entering a wrong password on purpose to verify the OID connection and it does recognize the password is wrong.  Also logged into ODSM (Oracle Directory Services Manager) with the right and wrong credentials to test and verify the credentials were correct.

Also verified the following Note does not apply to this issue, as otherwise able to add entries to OID without problems:

Creating User / Entry In OID Fails With: User Creation Error: [LDAP: error code 1 - Operations Error] / Adding BPEL JAZN Permissions Fails With: LDAP error code 20 - attribute or value exists Document 338540.1
