ldap_compare
Since LDAP permits the value of an attribute to be made available for
comparison, while not actually bieng able to be read, PHP provides the boolean
ldap_compare(resource link_identifier, string dn, string attribute, string value) function.
ldap_compare returns TRUE if the value specified attribute of the given dn
matches that of the passed value.
For simple checks against the directory this is also significantly less code to
perform a comparison than the ldap_search, ldap_get_entries, ldap_free_result
trio.
$r = ldap_compare($ds, "cn=Adam Williams,ou=People,dc=Whitemice,dc=Org", "morrisonvpnaccess", "Y");
if ($r = -1)
echo "Error: " . ldap_error($ds);
ldap_compare returns:
else
TRUE on a successful comparison
if ($r)
FALSE on a non-true comparison
echo "VPN Access Granted";
(-1) if an error occurred.
else
ldap_compare cannot be used on binary values.
echo "VPN Access Denied";
