I have been asked this question.
Can Two separate Discourse Instances share and use the same Database.
Scenario:
One Company that has global Offices locations.
Office and Location 1 named COMPANY [Foobu.Foobu.com](http://Foobu.Foobu.com) is located in Country X
Office and Location 2 named COMPANy [Foobu.Foobull.com](http://Foobu.Foobull.com) is location in Country Y.
REASON FOR THIS:
Company 1 is the RESEARCH unit located here in Home country.
COMPANY 2 is Support Unit located Outside home country.
They don’t want the folks Outside the Home Country to read what’s being shared in the Research unit.
If this is not possible, as I don’t think it is; how do you suggest I explain this other than lengthy Technical stuff they may not understand …anyway.?

> I know that it is possible to run multiple instances of discourse on the same server using a multisite setup. I’m wondering if it would be possible for multiple instances of discourse to make use of the same user database? So that a user could sign-up on any one of several different forums and use those same credentials to log in to all of the others. If a user’s whole profile (trust level, profile detail, pictures, etc) could be synced across each instance, this would be ideal for our use-case. …

> So you want to use Discourse as an identity provider for your own web app? Great! Let’s get started. Enable [DiscourseConnect](https://meta.discourse.org/t/13045?silent=true) provider setting Under Discourse admin site settings (/admin/site\_settings) enable setting enable discourse connect provider and add a secret string to discourse connect provider secrets (used to hash SSO payloads).
