Password Tutorial

At some point you may want to have a set of web

     pages that are protected, requiring a username/password to gain access to. 
     This tutorial will show you how to set that up. This is geared towards the 
     Unix Apache/NCSA httpd servers. If you are using another web server, 
     you'll need to check that server's documentation to see how to do this.

Steps to Password-protect a Directory

First, create a subdirectory

     in your web area. For the sake of this tutorial I'm creating one beneath 
     the toolbox directory, and naming it "secure". Set the permissions on the 
     directory so that it's world readable/executable (so the web server can 
     get to it), then cd into it.

mkdir secure
chmod 755 secure
cd secure

Next you must create a .htaccess file inside the

     directory you want protected. Make it a new file, and enter the following 
     data. The items in bold are things you will want to change 
     depending on the location of these files and directories on your server.

AuthUserFile <B>/www/jacob/secure/.htpasswd</B>
AuthName Toolbox Example
AuthType Basic
require valid-user

The AuthName is what the user will see when

     they're prompted for a password - something to the effect of "Enter 
     Authorization for Toolbox Example".

Now you'll have to set up the password file. You'll need to use the htpasswd program. It is included with NCSA and Apache httpd servers, usually in the support subdirectory under the server root (try /usr/local/etc/httpd/support). You can also write your own program to generate encrypted passwords. You just want to have crypt(actual-password) be stored in the file.

Now for every userid you want to add to the password file, enter the following. (the -c is only required the first time; it indicates that you want to create the .htpasswd file).

   htpasswd -c <B>/www/jacob/secure/.htpasswd</B> user1
     [ you're prompted for the password for user1, note: the -c argument means to creat a new file]
   htpasswd <B>/www/jacob/secure/.htpasswd</B> user2
   htpasswd <B>/www/jacob/secure/.htpasswd</B> user3

Be sure to chmod these files (755, or readable by the

     web server), and now you're set.

Here is an <A href="http://www.genome.ou.edu/secure1/htaccess.html">example file</A> using the above code to check for security. The username is "jacob" and password is "arch".
