OM Web Viewer can indirectly support Security Assertion Markup Language (SAML) if you code a security exit to handle it. See Code the External Security Exit in our online documentation.
NOTE: This can be used for all security needs not just SAML.
Your External Security EXIT must catch all exceptions. If the exception is passed on to Web Viewer, minimal diagnostics are presented. We highly recommend that you place all code that might throw an exception in try/catch statements and write diagnostic information to your own log file.
