I'm trying to set up a single sign-on for my intranet. I've found a couple solutions online but I'm not sure if they apply to my particular situation.
I have several subdomains on the same server. One level of user should be able to access all subdomains and another level of user should only be able to access some subdomains.
Signing into one subdomain should make it so you don't have to log into any others.
Can anyone point me in the right direction? I'm on Ubuntu using Apache.
