Step 6 : Configure Apache for HTTP basic authentication

You must configure Apache to support HTTP basic authentication by adding the required modules.

Refer to the Apache Web server documentation for more information.

For the Apache 1.3 manual, go to http://httpd.apache.org/docs/1.3.
For the Apache 2.0 manual, go to http://httpd.apache.org/docs/2.0/.

Once the Apache Web server supports HTTP basic authentication, you must:

Add an user to the Apache Web server basic authentication file with the same login and password as defined for the client.
Apache provides the tool htpasswd that you can use to create the file and add the user. To add the user mylogin with the password mypassword to a new file called myusers:
```
$ htpasswd -c myusers mylogin mypassword
```
Note: To add additional users, remove the option '-c'.
Add an Apache Web server location directive that enables you to group several directives for one URL. (In the example, the URL is /fastcgi/ws/r/MyWebService).
The following example (based on Apache 2.0) defines the HTTP authentication type (Basic), with a user file (user-basic) containing the login and password of those who are allowed to access the service.
```
  <Location /fastcgi/ws/r/MyWebService>
     AllowOverride None
     Order allow,deny
     Allow from all
     #
     # Basic HTTP authenticate configuration
     #
     AuthName "Top secret"
     AuthType Basic
     AuthUserFile "D:/Apache-Server/conf/authenticate/myusers"
     Require valid-user # Means any user in the password file
</Location>
```
