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