I've searched the archives of this list, the web as best I can, and have this same question asked to the sssd-devel mailing list and can not seem to find an answer this my question. I have a RHEL 6.4 server with OpenLDAP 2.4.23-32.el6_4.1 and sssd 1.9.2-129.el6, both installed as standard RPM's from Redhat. I have ppolicy configured in slapd and on another RHEL6.4 system have sssd setup as a client. Everything works fine with password expires, grace periods, etc and sssd, if the user has to enter their password. But, if the user is using an SSH public key, setting the account as locked or the password is expired still allows them to log in. I can't seem to find a good solution that forces the user to change their password before they can login.
The specifics are. sshd_config is configured to use PAM. My pam.d auth config is standard for RHEL6 which is:
auth required pam_env.so
auth sufficient pam_fprintd.so
auth sufficient pam_unix.so nullok try_first_pass
auth requisite pam_succeed_if.so uid >= 500 quiet
auth sufficient pam_sss.so use_first_pass
auth required pam_deny.so
I've confirmed that when a user logs in from ssh with both password and ssh keys, they are going through the PAM sss.so just fine, by turning up the debugging levels and watching the logs. I've read everything I can find on sssd and it appears that for all cases of LDAP, sssd wants a single true/false value along the lines of nsAccountLocked. I can't find anything in ppolicy that sets true/false for account locked like other LDAP implementations do, all ppolicy seems to provide is pwdAccountLockedTime.
While the issue seems more like a limitation on sssd's side, I thought I'd ask on this list to see if anyone has been able to come up with a solution or if there is something in ppolicy I am missing for a true/false on, is DN=X locked or not.
