    Everything is set, I can also see all users when I type:

    # wbinfo -u.

    However, when I try to login, it only authenticates via pam_unix; pam_sss authentication is not at all checked.

    How can I fix that? SSSD is enabled and running.

    Good Evening,

    When I restart the sssd service with this command systemctl restart sssd, i have this error.

    Failed to read keytab [default]: no such file or directory
    Exiting the SSSD. Could not restart critical service [ mydomain ]

    Do you have an idea of ​​the problem please?

    Excellent post!! Thank you very much!

    Just a typo:

    “sudo realm permit -all” should be “sudo realm permit –all” (that’s a double – instead of just one)

    Also, in sssd.conf shouldn’t “dyndsn_refresh_interval = 43200” by “dyndns_refresh…” ?

    Is it possible to change the user desktop background from the Domain Controller?
    if we want to set a particular image for all linux users?
