Internet Explorer has a great feature that you hardly notice. The Authentication credentials of the current user will be used by default.
- Figure: Internet Explorer has the Integrated Authentication feature built in
In Firefox, if you sign-in to an internal server like SharePoint or CRM, you will get an authentication dialog. Even though you are already authenticated to the local domain.
- Figure: We want to avoid authenticating using Firefox (so it works like IE)
- Open Firefox
- Go to "about:config"
- Click "I'll be careful, I promise!"
- Enter in the Filter box above: "network.automatic"
- You see 2 records
- Double-click the second one - It is the key called network.automatic-ntlm-auth.trusted-uris
- Enter the servers delimited by ",", e.g. "aphrodite, mermaid"
- Close browser and test
- Figure: Showed how to find "network.automatic-ntlm-auth.trusted-uris" by using filter: "network.automatic"
More info on this blog: Firefox and Sharepoint.
Tip: To test this without the Integrated Authentication enabled, you need to clear your session. You do this via: Tools | Clear private data | Authenticated Sessions.
- Figure: To test you will need to clear your "Authenticated Sessions" to completely logout from a site (SharePoint, CRM)
