<p class="level0">When using Kerberos V5 authentication with a Windows based server, you should include the domain name in order for the server to successfully obtain a Kerberos Ticket. If you don't then the initial part of the authentication handshake may fail.
<p class="level0">When using NTLM, the user name can be specified simply as the user name without the domain name should the server be part of a single domain and forest.
<p class="level0">To include the domain name use either Down-Level Logon Name or UPN (User Principal Name) formats. For example, EXAMPLE\user and user@example.com respectively.
