The issue you are facing: I can find and talk with users from other groups. I was expecting an option to limit conversation to within groups only.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
-
Create two groups
-
Create two users, one in each group
-
Login with one user, and the other user can be found in Talk when searching
I’m not copying any logs yet, there are no errors I think, I’m not certain if this is an incorrect setup, or it is supposed to work like that. Is there any way to prevent a user from being able to find users in other groups?
