# sk171501 - SAML integration with Mobile Access Portal - Error 500

## Symptoms

- * RSA integration using SAML (Security Assertion Markup Language) protocol does not work as expected.
* The client receives a 500 notice about the Mobile Access Portal page: "This page isn't working 'example.domain.com' is currently unable to handle this request. HTTP ERROR 500"
* httpd debug shows:  
  `simplesamlphp ERR [b92dfd5418] SimpleSAML\\Error\\Error: UNHANDLEDEXCEPTION, referer: 'example.domain.com'`

## Cause

An SAML assertion error is taking place and it cannot be handled. In addition, the client receives a 500 notice about the Mobile Access Portal page. This suggests that the assertion error arriving at the gateway is wrong / potentially corrupted.  

A root cause is that there is a difference in the certificate string before and after we read it from the received metadata.
