LDAP_OPT_SERVER_CONTROLS and LDAP_OPT_CLIENT_CONTROLS require a list of controls, this means that the value must be an array of controls. A control consists of an oid identifying the control, an optional value, and an optional flag for criticality. In PHP a control is given by an array containing an element with the key oid and string value, and two optional elements. The optional elements are key value with string value and key iscritical with boolean value. iscritical defaults to false if not supplied. See » draft-ietf-ldapext-ldap-c-api-xx.txt for details. See also the second example below.

Note:

All TLS options must be set globally before ldap_connect() for ldaps connection or for the connection before ldap_start_tls().

value

The new value for the specified option.
