The AuthGroupFile line is used when you want to have multiple usernames. The third line is the title of the authentication message box that pops up, while the fourth line indicates that this uses Basic authentication. To the left of the colon is Xena, my dream warrior of love. It is sometimes included with the web server, so she might not have to look far. Unfortunately, my sysadmin doesn't listen to me, mainly because he is jealous of my good looks.
Crypt uses it to help munge up the first argument.
Anyway, place the output to the right of the colon next to your username, and you are done. And now you can make others imagine how those marks on the conference table got there. For more information, check out the Mosaic User Authentication Tutorial .
