While configuring app server getting an error " the caller is not authenticated by service blue prism" using
"WCF: Soap with message encryption and windows authentication".

Thanks in advance

Hi Vinod,

Have you reviewed our Knowledge Base article on this error?

KB: "How do I fix error "Caller was not authenticated by the service" on a SSO environment?"

In addition, it may be that the certificates in this environment were not set up correctly which can cause this type of error. The KB, "How do I set up certificate authentication?" has a checklist you can follow in tandem with the Securing Network Connectivity topic in our Online Help.

Hi Shruthi,

In my case its a ssl certificate and dns issue.
let me know
1. Did you open the ports 8199 for app server and 8181 for runtime resource?
2. are you using DNS?

The default server connection mode (WCF: SOAP with Message Encryption & Windows Authentication) authenticates using Windows / Active Directory.

If the remote machine and the server are in different domains or do not share an Active Directory that may be the cause.

WCF: Insecure connection mode does not validate server identity using active directory -- so it will work with this option.

Make sure to select the same Connection Mode in app server and the remote machine (RR/IC) to make it work.
