There is multiple domains for the communities in the org. User have to be able to have an opportunity to log in into all communities via one.
Example : Communities A,B. From external site_X User_1 logs into A. Then he goes to external site_Y, from Y he wants to see protected information and now its requires Login into community B.
Is it possible to create Community Sessions for multiple domains for one portal user in Salesforce ? Are there any ways to make this scenario work?
P.S. Example works with one domain in sandbox.
Any help will be appreciated, Thank you!
