  • After enabling the SAML, when the user is trying to log in, authentication failed with the following message in UI and in Server console.
    UI: "Unable to handle SAML Request"
    Server Console:

Environment

  • Liferay DXP 7.0

Resolution

  • The above error will come when the user doesn't have a screen name and trying to login in Liferay.
  • Key point: The user will be imported to Liferay only when all the required attributes are correctly mapped. Required attributes ensure successful authentication. Please refer to the required attribute below.
