9 | Revision 1: (02/25/2005) Updated codebase to include the _inject_bind_options function. This allows |
---|
10 | users to access the options in the ldap_set_option function appropriately. Most importantly |
---|
11 | LDAP Version 3 is now supported. See the examples for more information. Also fixed some minor |
---|
12 | bugs that surfaced when PHP error levels were set high. |
