We are successfully using Discourse with SSO from our main site. We have the sso_overrides_avatar setting set to true, and are passing the avatar url in the payload. This is working for standard accounts, but for the Admins the avatar is not shown.
If I look at the admin view of the user’s profile, I can see the Profile Picture URL populated with an external url. If I paste this url in a new browser window I see the correct avatar. The Profile Picture, however, (on this page and everywhere else) shows the standard shadow icon.
It is possible that these accounts were created before I enabled SSO, could that cause the problem?
Any suggestions how to start troubleshooting this?
