Single Sign on - Windows Active Directory

I need some help to satisfy this topic.

I think that this is called seamless authentication.

I need to learn more on this.

Hi Nils

Thanks for your work and time :)

I think the information you need would be located here.

Someone could also utilize Apaches feature to drag the windows-logon into the variables...

A more flexible method would be to use SAML based logins maybe?

Hi Nils, is there any progress with having SAML authentication?  That would be really nice to have SSO into this application.
