Before this patch, if the user was configured for either OTP or password it was possible to do a 1FA authentication through ipa-otpd. Because this correctly respected the configuration, it is not a security error. However, once we begin to insert authentication indicators into the Kerberos tickets, we cannot allow 1FA authentications through this code path. Otherwise the ticket would contain a 2FA indicator when only 1FA was actually performed. To solve this problem, we have ipa-otpd send a critical control during the bind operation which informs the LDAP server that it *MUST* validate an OTP token for authentication to be successful. Next, we implement support for this control in the ipa-pwd-extop plugin. The end result is that the bind operation will always fail if the control is present and no OTP is validated. https://fedorahosted.org/freeipa/ticket/433 Reviewed-By: Sumit Bose <sbose@redhat.com> |
