Unfortunately not how the browsers works. The selection is done by the browser based on the capabilities of the browser, not if the user is logged on to a domain. If the browsre is capable of performing Kerberos authentication then it will either use the already logged in AD credentials or promt the user for AD credentials, verified by the negotiate auth helper. If the browser is not capable of kerberos authentication it will prompt for plain username + password authentication validated by the basic auth helper. > But next, I'd like to match all users that are authenticated with > basic mode in separate acl.
