We have SharePoint, Project Server 2013 & Nintex Workflows 2013 based web application where SharePoint is configured with Claims based authentication.

We got a requirement to convert from claims to SAML based authentication in order to implement SSO with IAM.

I am looking to understand if On Premise Nintex Workflow 2013 supports SAML based authentication with SharePoint Server 2013 & webservices and if there are steps will be require to update existing workflows using SharePoint/Project webservices.
