The default account is "Admin" there is no default password. If you upgrade to 3.4, then the software asks you to supply a password for the Admin account during the installation process.
The base software is Apache, if you're familiar (or know someone who is) then all the "usual" rules apply relating to passwords, directory alias, .htaccess files, etc.
Off the top of my head, I believe the httpd.conf file is in PROGRAM FILES|CISCO|CONTENT MANAGER|APACHE|CONF. But you may need a password to get there, depending on how you're accessing the server.
Good Luck
