I installed an instance of Digital.ai Agility on my own server. Now I don't have a Logout link.
How to Fix It
You probably selected Windows Integrated as your authentication mode. When Digital.ai Agility is installed locally and Windows Integrated Authentication is selected, Digital.ai Agility doesn't authenticate users. Instead, IIS authenticates each user against the Active Directory and passes the user through to Digital.ai Agility.
Since it is not possible to "logout" under Windows Integrated Authentication, the Digital.ai Agility web application has no "logout" link (Digital.ai Agility has no control over the authenticated user passed over by IIS).
To change your authentication mode, simply re-run the installer as an upgrade and select a different authentication mode.
