Project Server certificate authentication

Question

I need to know if MS Project Server 2013 requires client-side certificate authentication so that I can implement correctly the authentication part  in my client app that needs to access the REST APIs of Project Server, and handle accordingly the server's
certificate.
Thanks in advance.

Answer 1

what is the error occurred when the custom PSI app connects?
can you upload the ULS logs here for research?
What is the user account format you specified in the code for authentication?
For proper authorization, the “user logon account” in PWA for the user needs to be changed from domain\username to the claims token (e.g.
'I:0#.w|mybusinessdomain\ewmccarty').
It requires you to manually call the UpnLogon method of
“Claims to Windows Token Service”. if (Thread.CurrentPrincipal.Identity is ClaimsIdentity)  
{  var identity = (ClaimsIdentity)Thread.CurrentPrincipal.Identity;  }  
if (Thread.CurrentPrincipal.Identity is ClaimsIdentity)
var identity = (ClaimsIdentity)Thread.CurrentPrincipal.Identity;
Than you need to extract UPN-Claim from the identity.
Upload the verbose log if possible.
