Example

The following example demostrates how to use the APEX_LDAP.AUTHENTICATE function to verify user credentials against an LDAP Server.

IF APEX_LDAP.AUTHENTICATE(
    p_username => 'firstname.lastname',
    p_password => 'abcdef',
    p_search_base => 'cn=user,l=amer,dc=example,dc=com',
    p_host => 'our_ldap_sever.example.com',
    p_port => '636',
    p_use_ssl => 'A') THEN
 
    dbms_output.put_line('authenticated');
ELSE
    dbms_output.put_line('authentication failed');
END IF;
