title: SimpleSAML and Symantec O3
body: <p>I'm trying to configure SimpleSAML to allow authentication via an external login portal powered by Symantec O3. </p>
  
  <p>I've set up SimpleSAML as a SP by editing config/authsources.php and converting the respectful meta data. I've provided my meta data to the administrators of the external login portal. </p>
  
  <p>When I visit the test authentication page, I am correctly redirected to the login portal however after logging in I get redirected back to SimpleSAML but instead of seeing my identify information I receive the following error:</p>

  <p>It appears not to know where to redirect to after authentication. </p>
  
  <p>This doesn't look like an issue with the test functionality as although it appears to authenticate I get the same error message when implementing the authentication in a plain php file. Is there any particular configuration I should check and set? </p>
