10. UNBIND_LDAP

These are the DFHDDAPX calls.The CICS Internet Guide provides more

information on use of these functions.

The BIND_LDAP call

The BIND_LDAP call establishes a session with an LDAP server. The server is

identified by one of the following:

v The LDAP URL and the distinguished name and password of the user authorized

to extract the expected data.

v A RACF profile in the LDAPBIND class that contains the LDAP URL and

distinguished name and password. This is the preferred option, as you do not

need to code LDAP credentials in your application.
