Troubleshoot

Please contact us with chat or at Slack community.

  • /logout force sign out
  • Without group sync, new user will be created but has no access to the team.
  • Without group sync, same email users are only accessible from Okta.
  • With group sync, mapping of 'Everyone' to 'Viewer' allows all employees can access with no extra grant.
  • With group sync, role update are logged by cloud.
  • Since SelectAdmin do not cache or save groups names from your Okta, there is no validation for group name misspells.
  • For any reason, by request of non-verified admin, we cannot turn off any security option instead of owner.
