Last updated on MARCH 08, 2017

Applies to:

Oracle Internet Directory - Version 10.1.2 to 11.1.1 [Release 10gR2 to 11g]
Oracle Unified Directory - Version 11.1.1.5.0 and later
Information in this document applies to any platform.

Symptoms

Directory Integration Platform (DIP) with third party directory, such as Active Directory (AD).

Import synchronization slow performance in adding some new AD entries into backend directory.  Multiple users are created in AD at the same time, but while some of the users are sync'd to backend directory timely, others are delayed by a day or longer before they are imported into backend directory.

For example, consider the following two users creation details in AD, obtained by searching AD for their respective whenCreated attribute values:

ldapsearch -h <AD hostname> -p 389 -D "<ADAdmin@domain>" -w <password> -s sub -b "OU=myou,DC=mycompany,DC=com" "cn=username1" | grep whenCreated
whenCreated=20110922181041.0Z

ldapsearch -h <AD hostname> -p 389 -D "<ADAdmin@domain>" -w <password> -s sub -b "OU=myou,DC=mycompany,DC=com" "cn=username2" | grep whenCreated
whenCreated=20110923123734.0Z



For OID 10g as backend directory, the profile audit file $ORACLE_HOME/ldap/odi/log/<profilename>.aud indeed shows those users are added to backend directory a day later, for example:
