Hi Experts

We have serveral partners each with thier own login URL, which we would like to bring into a single shared login screen.

e.g.
myinstance.force.com/partner1/login
​myinstance.force.com/partner2/login

Is there a way to have one single login screen and it login to the correct partner depending on thier username/profile?

e.g.
myinstance.force.com/login

Any help would be apreciated.

Nick
