The mailing list for listmasters using Sympa

[<address@concealed>]

Hi,

I am failing to use the SOAP login method requesting the demo mailing list
service at demo.sympa.org. I registered an account at the demo mailing list
service, copied your https://demo.sympa.org/sampleClient.php to our
development server and tried to make a login with the following demo
credentials:

    http://development.stadtwerk.org/sympa/demo

    E-Mail: address@concealed
    Password: sa-demo


The result is a fatal PHP error:

    Fatal error: Uncaught SoapFault exception: [HTTP] Forbidden in /www/
htdocs/w00c2aba/development/sympa/demo.php:41
    Stack trace:
    #0 [internal function]: SoapClient->__doRequest('<?xml version="...',
'http://demo.sym...', 'urn:sympasoap#l...', 1, 0)
    #1 /www/htdocs/w00c2aba/development/sympa/demo.php(41): SoapClient-
>__call('login', Array)
    #2 /www/htdocs/w00c2aba/development/sympa/demo.php(41): SoapClient-
>login('rudolph@stadtwe...', 'sa-demo')
    #3 {main} thrown in /www/htdocs/w00c2aba/development/sympa/demo.php on
line 41


I then build my own test code with the PHP SoapClient Object and enabled HTTPS
on the test server, which also throws an exception:

    https://ssl-account.com/development.stadtwerk.org/sympa/


It all boils down to "[HTTP] Forbidden", hence my question: Am I allowed to
query the demo list via SOAP from another domain than sympa.org?
