# Common SSO issues

<AccordionGroup>
  <Accordion title="I get an error when logging in">
    There could be many reasons why an SSO login failed. In general it's one of the following issues.

    * The app set up for SSO is not a SAML app, this likely results in a failure to log into the identity provider.
    * The log in URL or certificate provided are not correct, which causes a validation error on log in.
    * An incorrect URN was set up, which causes a validation error on log in.
    * One of the expected `name`, `email` and `gr4vy_roles` user claims was not provided. This stops
      the mapping of an SSO user to a dashboard user.
