$cfg['Servers'][$i]['SignonScript'] is broken

[lbausch]

Steps to reproduce

1. Set $cfg['Servers'][$i]['auth_type'] = 'signon';
2. Set $cfg['Servers'][$i]['SignonScript'] = './myscript.php';
3. Open phpMyAdmin in browser

Expected behaviour

myscript.php should be sourced and used to obtain login credentials

Actual behaviour

Error page is displayed, saying

phpMyAdmin - Error
You must set SignonURL!

Server configuration

Operating system: Debian 7.11

Web server: Apache 2.2.22

Database: MySQL 5.5.55

PHP version: PHP 5.4

phpMyAdmin version: 3.4.11.1deb2+deb7u8

Client configuration

Browser: Chromium

Operating system: Debian

Apparently you don't have set $cfg['Servers'][$i]['SignonURL'], please set it.

You get to this point because SignonScript didn't return valid credentials and phpMyAdmin tries to redirect to SignonURL.

[lbausch]

The SignonScript is never sourced - that's the problem.

[lbausch]

if SignonURL is set an instant redirect happens - and SignonScript is ignored.

Am I misreading the docs here?

Oh, I've just noticed that you're using quite old version, that doesn't support SignonScript, it was introduced later in 72886c3.
