Description Vincent Danen 2014-11-05 20:48:02 UTC
A flaw was reported [1] in FreeIPA 4.0/4.1 where users could log in using only the OTP value. This arose because ipapwd_authentication() successfully determined that an empty password was invalid, but 389 itself would see this as an anonymous bind.

This will be fixed in the next release [2].  As support for OTP is not available in earlier versions, only FreeIPA >= 4.0 is affected.

Acknowledgements:

Red Hat would like to thank FreeIPA upstream for reporting this issue.


Statement:

This issue did not affect the versions of IPA as shipped with Red Hat Enterprise Linux 5, 6, or 7 as they did not include support for OTP.
