What is the expected output? What do you see instead?

Expect no warning message. Instead, I get this warning before the auth
process proceeds:

Warning: Call-time pass-by-reference has been deprecated; If you would like
to pass it by reference, modify the declaration of [runtime function
name](). If you would like to enable call-time pass-by-reference, you can
set allow_call_time_pass_reference to true in your INI file in
/home/xxx/wp-content/plugins/openid/Auth/OpenID/AX.php on line 891
