Configuring Authentication for Web Users 920-221 70-299 70-541
Active Directory is a perfect way to store credentials for internal users because it can provide single sign-on authentication for a variety of network resources, including Web servers. If your organization provides an internal Web site, the Web site should authenticate users by using their existing Active Directory user accounts. If the Web site accesses information on the user’s behalf, such as querying a database to retrieve confidential benefits information, the Web site should access that information by using the user’s own credentials.
Active Directory is not the ideal way to store credentials for external users. Many organizations invite customers, potential customers, and partners outside the organization to access information, files, and data. Today, information is usually shared with external users by means of a Web site. If the Web site allows anyone on the Internet to access content, these Web users will be considered anonymous. However, the anonymous user’s requests must still be issued in the context of a valid security principal in order to access files and data.
Configuring Anonymous Access for Web Users
Most public Web sites on the Internet allow anonymous access for at least a portion of the site. In other words, the general public can retrieve pages from the Web server without providing credentials. This does not mean that authentication is not taking place, however. Any user or process that accesses a file or other network resource must do so in the context of a security principal (a user, a computer, or a service account). When Internet Information Services (IIS) accesses files to be sent to an anonymous user, it uses a specified user account to access those files. When anonymous access is not allowed, users must provide their own credentials. XK0-002 70-536 646-230
As an administrator, you can control which user account IIS uses to access files and other network resources on behalf of anonymous users. By default, this account is automatically created during the IIS installation process and is named IUSR_computername. To specify different user credentials for IIS to use when accessing files and resources on behalf of an anonymous user, first create a new user account, and then follow these steps:
-
Log on to the computer as an administrator.
-
Click Start, click Administrative Tools, and then click Internet Information Services Manager.
-
Expand the computer node, and then expand the Web Sites folder. Right-click the node for the Web site you are editing, and then click Properties.
-
Click the Directory Security tab. In the Authentication And Access Control grouping, click the Edit button.
-
The Authentication Methods dialog box appears. Type the user’s credentials in the User Name and Password fields, and then click OK.
-
Click OK again to return to the Internet Information Services Manager.
