                     11: The user name and passwords are split up on the first colon, which makes it
                     12: impossible to use a colon in the user name with this option. The password can,
                     13: still.
                     14: 
                     15: On systems where it works, curl will hide the given option argument from

                     21: When using Kerberos V5 with a Windows based server you should include the
                     22: Windows domain name in the user name, in order for the server to successfully
                     23: obtain a Kerberos Ticket. If you don't then the initial authentication

                     26: When using NTLM, the user name can be specified simply as the user name,

                     28: for example.
