Hi
Does anyone know of a (pre-written) web service or similar that one can plug into a website to allow logging in across multiple websites.
e.g.,
Say we had three websites on completely seperate web servers, each with their own member login system and membership database and we wanted to allow all the members to all three sites to login in to whichever site within the group they wanted to.
If a member belonging to site 1 logged in and then browsed to site 2, that member should not have to log in again (despite not being setup on that site). Or, if he belonged to site 1 and tried to login to site 2 then this should also allow him through even though his details are held on site 1.
The sites do not have access to each other’s data/databases etc.
There would obviously be a kind of trust-thing set up so only certain sites could participate.
Does this sound like something that could be acheived with web services? Each site is able to set something up to allow this.
I have looked at numerous options, including sharing out a database between the sites but I have not come to a satisfactory (and secure) conclusion.
Can anyone help?
Thanks
Jo
