Hi all, I am trying to get single signon funtionality in my EPiServer app by setting the authentication mode to 'Windows' as in the following example : http://www.episerver.com/en/EPiServer_Knowledge_Center/Support/FAQ_EPiServer_4/1010/6425/ This works fine in development as the client and webserver sit on the same domain. However, the live server isnt on the domain and cannot authenticate the user. Is there some way that I can still use Integrated Windows Authentication to pass the user credentials and then have a custom logon to look authenticate the user through LDAP (or something). Regards, Shane
