Description Matt Crawford 2017-04-28 20:24:59 UTC 
Description of problem:
Kerberos through MIT 1.15 is not compatible with PIV and PIV-I smartcards

Version-Release number of selected component (if applicable):
1.14.3

How reproducible:
Attempt to authenticate by PKINIT with "kinit -X ..." and a government-format PIV or PIV-I smartcard

Steps to Reproduce:
1. Configure realm for pkinit
2. Attempt to authenticate as client with "kinit -X ..." and PIV-I card.

Actual results:
KDC rejects because it cannot be made to recognize the user's certificate


Expected results:
(Hoped-for results) TGT is obtained.

Additional info:
In the 1.16 release, MIT added a per-principal pattern-matching capability to the KDC preauth plugin for pkinit. This solves the compatibility problem for a great many sites such as the DOE National Labs. As soon as the 1.16 code is in released state from MIT, please make it the base for RHEL.
Comment 5 Robbie Harwood 2017-10-09 17:42:44 UTC 
The certauth plugin (which I believe is what is described here) was included in rhel-7.4.
Comment 6 Pat Riehecky 2017-10-09 18:15:56 UTC 
Manpage for krb5.conf does have pkinit_cert_match which is the key feature from 1.16.
