I have to mention that I am new to IIS. I have a local IIS 8.5 on a windows server 2012 machine. When I enable the windows authentication (basic authentication is disabled), I can access and see the home page of IIS (http://localhost) with the credentials of a LDAP user in the same domain. However, when I enable basic authentication (windows authentication is disabled), I cannot access the home page with the same credentials I used for windows (The authentication pop up never goes away).
Shouldn't the same credentials work for both basic and windows authentication or basic authentication works differently ? If not, then how are the credentials validated in case of basic authentication ?
Note: Eventually I plan to write restlet java code to post resources using basic authentication.
So finally I got this problem solved. For Basic Authentication (click on edit), we need to set the default domain (realm is optional). Once I set the default domain, I could login using the LDAP user credentials.
