The first step to troubleshoot this error is to make sure that you are passing a valid platform user role in your SAML assertion:

• cloudhealth-administrator
• cloudhealth-power
• cloudhealth-standard 

Failing to do so will also result in an 'Invalid role' error when signing into the platform. 

-----

PingFederate appends the characters 'CN=' to the specified user role within the 'roles' attribute (Ex. 'CN=cloudhealth-administrator') of the SAML assertion. This causes an 'Invalid role' error when signing into CloudHealth. To remove these extra characters you will want to add the below OGNL expression to PingFederate:

#theCNValues = new java.util.ArrayList(), #vals = #this.get("ds.memberOf").getValues(), #i = 0, #vals.{ #val = #vals[#i], #newVal = #val.toString().substring(3, #val.indexOf(",")), @java.lang.System@out.println(#val + " => " + #newVal), #theCNValues.add(#newVal), #i = #i + 1 }, #this.get("ds.memberOf")!=null? new org.sourceid.saml20.adapter.attribute.AttributeValue(#theCNValues):null
