I’ve had SSO running nicely for a couple of months, but I am having trouble with one user account which was created prior to SSO. On my main site with username U1 they use email E1 but their good community account U1 used E2. So when they try to sign in now Discourse created a new account U2 with E1.
I’ve tried to correct this by deleting U2 from Discourse, and I tried to impersonate them as U1 and update their email address to E1. It said it emailed them but they didn’t see it, and I am not even positive if this will fix the problem.
I can confirm the problem myself - when I impersonate them on my main site was U1, it’s still creating U2 on Discourse. Help appreciated! Thanks.
