Putting It Together

Putting It TogetherVisiting http://my.lboro.ac.uk: – Shibboleth prompts for SSO login if necessary • SAML response includes LDAP attributes from Active Directory, e.g. student ID – Populates skeleton HTML of page • Starts AJAX callbacks going to render widgets • Choice of staff/student content – Appearance driven via CSS + jQuery

Traps for the Unwary• Are you using UTF-8 everywhere?• SimpleXMLElement barfs on malformed XML• How much intermediate caching to do?• Do you even have APIs??• 2 Legged OAuth not well understood• REST good, SOAP bad – but use JSON rather than XML if you can• print_r() and Data::Dumper are your friends!
