I'm trying to setup Salesforce Delegated Authentication with NAM 4.4.1 following this guide. After follow all the needed steps, when I test it with Post Man I receive an "HTTP 500 Internal Server Error". At the NIDP log file I can see the following error:
com.mf.soap.ep.NAMAuthenticationUtil: NAMAuthenticationUtil.java: authenticate: 38
com.mf.soap.ep.SalesForceDelegateAuthEP: SalesForceDelegateAuthEP.java: doPost: 70
Any idea of what can be wrong?
