Basic authentication is a common form of Web site protection. With Basic authentication, the Web browser client prompts for a user name and password and sends this information in either plain or encrypted text to the Web server. In Centrify for Apache, Basic authentication uses Active Directory for Basic Authentication (see the Enable ... directives in the table Extensions to Apache Directives).
Note: The default configuration authenticates all requests are validated against accounts in the Active Directory domain controller. If you want to support local authentication, use the PAM authentication.
Note: Using Basic authentication on Web servers that are not configured to use the Secure Socket Layer (SSL) protocol allows user passwords to be sent across the network unencrypted in plain text. In most cases, therefore, you should configure the Web service to use https and the Secure Socket Layer (SSL) protocol if you have applications that use Basic authentication. Configuring SSL for a Web service does not require any modifications to your Centrify for Apache configuration.
To enable Basic authentication, the Web page, Web directory, virtual Web site, or entire Web site must be configured to be protected with Basic authentication.
