IdP authentication to webservice

[Petr Novak]

Hello, 

please help me: I need to to configure IdP authentication to non-standard interface (no LDAP or AD or Kerberos).

Client website calls server by POST method on defined URL with following structure:

https://auth.example.edu/auth.php?username="value"&password="value"

auth server then returns xml formatted response:

authentication succesfull:
<?xml version="1.0" encoding="UTF-8" ?>
<auth xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <result>1</result>
   <person>
      <identifier>12345</identifier>
      <name>John</name>    
      <surname>Newman</surname>
      <email>john at newman.com</email>
      <affiliation>student</affiliation>
   </person>
</auth>

authentication not succesfull:
<?xml version="1.0" encoding="UTF-8" ?>
<auth xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <result>0</result>
</auth>

How to configure authentication and attribute resolution?

Thank you for any help
