Can not set LDAP_OPT_NETWORK_TIMEOUT on php 8.4

[amorebietakoUdala]

Description

The following code:

$ldap=ldap_connect("ldap://127.0.0.1");
var_dump(ldap_set_option($ldap,LDAP_OPT_NETWORK_TIMEOUT,3));
'

Resulted in this output:

bool(false)

But I expected this output instead:

bool(false)

LDAP_OPT_PROTOCOL_VERSION doesn't work either.
