I wanted to have totally 3 subdomains under one domain. I am planning to install silverstripe on the main domain and on all 3 subdomains. Is it possible to have a single signon and single database for all the subdomains as the main domain ? or should i create separate databases for everything ?

THanks,

Hey Nandhi,

It depends if you are running three completely separate SilverStripe websites on your subdomains then you will need three separate databases (1 per website).

Another option you could look at is the subsites module http://addons.silverstripe.org/add-ons/silverstripe/subsites

For single sign on you might be able to use the opauth module for social sign ins https://github.com/BetterBrief/silverstripe-opauth

I haven't seen a cross subdomain single sign on implementation personally though you could perhaps try talking to some of the developers in the IRC channel about this.

As camfindlay says, if you are happy to run one master install, then subsites is the way to go. That way you run all three sites through one DB and have one set of credentials for all 3.

You can restrict access to each subsite so only certain users can access certain sties (if that makes sense)?
