How to decode a SAML response when it is encoded

Troubleshooting


Problem

When federated users have issues logging in, we require a SAML trace to determine if the assertion has the exact required attributes: firstName, lastName, country and emailAddress. Sometimes when a SAML trace is taken, the response is encoded. This must be decoded before the investigation can proceed.

Symptom

SAML trace provided by the customer has this type of response (the response has been snipped to save space): 
SAMLResponse=PD94bWwgdmVyc2lvbj  <snip> wyOkFzc2VydGlvbj48L3NhbWwycDpSZXNwb25zZT4%3D&RelayState=uuid22e22a01-016c-1986-b566-d3302c8ac5b3
