2.9. Logging in to an IdM client via SSH as an external IdP user


To log in to an IdM client via SSH as an external identity provider (IdP) user, begin the login process on the command linel. When prompted, perform the authentication process at the website associated with the IdP, and finish the process at the Identity Management (IdM) client.

Prerequisites

Procedure

  1. Attempt to log in to the IdM client via SSH.

    [user@client ~]$ ssh idm-user-with-external-idp@client.idm.example.com
    (idm-user-with-external-idp@client.idm.example.com) Authenticate at https://oauth2.idp.com:8443/auth/realms/main/device?user_code=XYFL-ROYR and press ENTER.
  2. In a browser, authenticate as the user at the website provided in the command output.
  3. At the command line, press the Enter key to finish the authentication process.

Verification

  • Display your Kerberos ticket information and confirm that the line config: pa_type shows 152 for pre-authentication with an external IdP.
