So ive been going round in cirles for a couple of days trying to work this out. I have a multisite network and im trying to allow users of all sites in the network to have single sign on to all other sites (ie if you are logged in to one sight, you are logged into all of them).
I am using both mapped domains and multidomain subdomains for my sites. Mapped domains and multi-domain plugins seem to handle SSO differently. In multidomains there is simply an 'on/off' SSO button, for mapped there is an option for 'cross domain auto-login', which may be loaded asynchronously if option is selected.
Unfortunately, only some of the sites on the network seem to allow SSO. It doesnt seem to be related to the theme used or other plugins - ive tested extensivly. I have also tried all combos of SSO options in multidomains and domain mapping but no joy.
If you log in at finalstutor.com, you can also access medrocket.cloud and webapp.finalstutor.com, but not medrocket.net
If you login at webapp.finalstutor.com you can also access medrocket.cloud but no others
If you login at medrocket.net you can also access medrocket.cloud but no others
If you log in at medrocket.cloud you cant access any others.
There must be some kind of pattern here to explain how the cookies are working but i cant figure it out!
Any help to get this working would be hugely appreciated! Ive opended my dashboard if it helps.
