Configuring Oracle Cloud as the Service Provider with SimpleSAMLphp as IDP

In order to establish SSO between enteprise backend and Oracle Public Cloud, it's possible to use SimpleSAMLphp (Federation tool) as an in-house Identity Provider, and setup Oracle Cloud as the Service Povider.
Cf official documentation Managing Single Sign-On about the concept.
SSO relies on SAML 2.0 standard.

Tasks

At the Identity Server (IDP) level

  • Install Apache and PHP 5.3 +
  • Install SimpleSAMLphp
  • Just Follow documentation and yum install php53-mcrypt  instead php-mcrypt if linux complains about it.
  • Test with a simple SP provided with SimplePHPphp.
  • Don't forget to un-comment the example-userpass !
  • Export the metadata in a XML file

At the Cloud Service level

  • Import the previous metadata file
  • Accept default values and don't change anything.
  • At the IDP server level: 
    • Follow documentation Servive Provider Quickstart
      • Update the config/authsources.php with infos provided in the parameter pages (entity Id)
      • EntityID value must be the same value as Provider Id
      • Let's stay in http (vs https) mode for demo purpose
  • Test the SSO (cf output below)
  • enable it, only if test is ok.
Output Display after SSO test

Oracle Documents Cloud Service - Using Upload File REST API

If the Upload File sample given in ODCS documentation is used "as is", we get a http 400 error. The syntax is strict and every blank line must be empty (no space character for instance). If we cust and paste the sample, there are residual space characters which must be removed. So, use this pattern instead: -----1234567890 Content-Disposition: form-data; name="jsonInputParameters" { "parentID": " " } -----1234567890 Content-Disposition: form-data; name="primaryFile"; filename="example.txt" Content-Type: text/plain Hello World! -----1234567890-- instead the original one: -----1234567890 Content-Disposition: form-data; name="jsonInputParameters" { "parentID":"FB4CD874EF94CD2CC1B60B72T0000000000100000001" } -----1234567890 Content-Disposition: form-data; name="primaryFile"; filename="example.txt" Content-Type: text/plain -----1234567890-- Tests can be...

Oracle Sites Cloud Service - Apps

It's possible to add kinds of widgets (named APPS) inside any page of a site built with Oracle Sites Cloud Service (SCS). Any app is materialized by two URL: a Renderer Url which will render any HTML fragment inside an iframe tag at runtime a settings url which will be rendrered at design time in the settings menu. all URLs must be called through https (meaning that the called server has to be ssl enabled) In the following samples, we integrate: a dummy app (a simple html page produced with node.js) which demonstrates the parameteres caried by the Sites Cloud engine when calling the backend server,  a regular Apex report or form,  a custom report which calls a rest api generated by Apex /ORDS Sample node.js server.js below is a sample of parameter values get from a dummy node.js server Main call id=26e45e21-dbb6-4877-9886-482b37213d2f instance=eyJpbnN0YW5jZWlkIjoiQTI0NUNFNUNFNjA5MjE1REZBRTA2RTQyRjExOThBNThFNzc4RDc5NzFDMkIiLCJzaWduZGF0ZSI6IjE0NTAxMDg1M...
