Authentication Methods

You can configure which authentication method to use. You can configure different authentication methods for incoming Web requests and for outgoing Web requests.

ISA Server supports the following authentication methods: basic authentication, digest authentication, Integrated Windows authentication, and client certificates and server certificates.

Microsoft Internet Explorer 5 supports all the authentication methods. Other Web browsers may support only the basic authentication method. Be sure that the client Web browsers can use at least one of the authentication methods that you specify in an array's incoming Web request and outgoing Web request properties. Otherwise, the client will not be able to access the requested object.
