title: Sending a SAML Assertion to the Intuit OAuth Server
body: <p>Recently I researched a PHP Sample (PHP Sample App and Authentication Example) but I still can't make it work. <em><a href="https://stackoverflow.com/questions/17649847/aggcat-php-sample-is-not-working">aggcat php sample is not working</a></em></p>
  
  <p>Did anybody test this sample? Should I use the .crt file for 'SAML_X509_PRIVATE_KEY_PATH' or .p12 file? In case of using .p12 file where I could pass the password?</p>
  
  <p>What other samples (open-source) would you recommend (that can be used to implement my own procedures for retrieving OAuth access token and OAuth access token secret)? Thanks in advance.</p>
