The PAM config files are the same on both systems, here is the contents auf common-auth
auth [success=2 default=ignore] pam_sss.so forward_pass auth [success=1 default=ignore] pam_unix.so use_first_pass # here's the fallback if no module succeeds auth requisite pam_deny.so # prime the stack with a positive return value if there isn't one already; # this avoids us returning an error just because nothing sets a success code # since the modules above will each just jump around auth required pam_permit.so
I've prepared two tarballs with full logs of both a successful attempt to login on sssd 1.15.1/Ubuntu 16.04 and an unsuccessful attempt on 1.16.1/18.04. I would like to send you these tarballs in private. Can you provide me with an e-mal adress to send to?
