title: How I can verify credentials for domain name with Credentials-plugin in jenkins
body: <p>I want to verify and validate credentials (user and password) by using Credentials-plugin for Jenkins. I added Credentials-plugin in my POM file. But I don't know how to verify access to my domain name.</p>
  
  <p>Do you have any idea how I can verify credentials for a domain name (aa.example.com) by using credentials-plugin through java.
  Thanks</p>
