Component : CA LDAP Server for z/OS
That helps the LDAP code differentiate because there are different Field Names returned for the different modes, and also what LDAP backend is used.
The LDAP server is a basic LDAP server. There are "backends" to access a product. A call comes in using LDAP protocol, CA-LDAP server processes it, and then send it to the product using the "backend". Development has written ones for ACF2, Top Secret, RACF, DB2, IDM and a few others. Customers can write their own for other products.
