I could not see authorisation phase; neither in sssd_pam log nor in
sssd_$domain.log.

It means that you either shared just part of log file or that
your application did not reach/try line "account" in pam stack
  "account required pam_sss.so"
In this case you would able to see PAM_ACCT_MGMT in log files.

sssd seems to work as expected.
