Dmitri is completely right. When you log in with your public key the authentication is performed by sshd, so the SSSD's pam_sss doesn't come to play in the authentication. Some password policies (eg shadow) would be possible to check later during the account phase, but typically the expiration data is returned by the LDAP server during authentication, so this solution wouldn't be generic. Also, by using public keys, you are logging in with another authentication token then your password, so it would seem strange a bit to warn about password properties. Account expiration is a different matter than password policy. Expiration should always be checked during account phase. I'm not sure which mechanism is most prevalent in OpenLDAP deployments, but please check the sssd-ldap man page, option 'ldap_account_expire_policy'. If there is some widely used overlay or other mechanism which is not supported by the SSSD, let us know. _______________________________________________ sssd-devel mailing list sssd-devel@lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/sssd-devel
