TDM Portal authentication failing from Javelin

Products

• CA Test Data Manager (Data Finder / Grid Tools)

Issue/Introduction

We have just installed the new version of TDM package (4.11.71.0) in our environment.

Our complex model that uses Javelin to interact with TDM Portal fails calling the Portal service that generates the token.
When using the AuthenticatePortalUser activity, getting below error:

Environment

TDM 4.11.x

Cause

Configuration for TLS version in latest Tomcat of 4.11 by default uses TLSv1.3.

Resolution

1. Go to "C:\\Program Files\\CA\\CA Test Data Manager Portal\\tomcat\\conf" directory (adjust the path based on Portal installation location).

2. Edit file "server.xml" - search for "protocols" attribute and set its value to "TLSv1.2+TLSv1.3" (from "TLSv1.3").

3. Restart Portal service.
