If you turn on digest
authentication, type the realm name in theRealm????? ????
Basic authentication (password is sent in clear
text): Basic authentication requires a user ID and password, and
provides a low level of security. User credentials are sent in clear text
across the network. This format provides a low level of security because the
password can be read by almost all protocol analyzers. However, it is
compatible with the widest number of Web clients. This option is best used when
you want to grant access to information with little or no need for privacy.
If you turn on basic authentication, type the domain name that you
want to use in theDefault domain????? ???? You can also optionally
enter a value in theRealm????? ????
Microsoft .NET Passport
authentication: .NET Passport authentication provides single sign-in
security, which provides users with access to diverse services on the Internet.
When you select this option, requests to IIS must contain valid .NET Passport
credentials on either the query string or in the cookie. If IIS does not detect
.NET Passport credentials, requests are redirected to the .NET Passport logon
page.
???:When you select this option, all other authentication methods
are unavailable (appear dimmed).
Another type of authentication is based on the requesting
host instead of on user credentials. You can limit access based on source IP
address, source network ID, or source domain name. To configure this type of
authentication, follow these steps:

You may be prompted to apply any changes that you have made
to existing sites. If you want the authentication changes applied to other
content, click the content from the list of child nodes, and then clickOK. If you do not want the changes applied to any of the child
nodes, do not select any items on the list, and then clickOK.
In IIS, you can set authentication options at the Web site,
directory, or file level. The same principles that are discussed in this
article apply to each.
