This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: In case KDC is configured to use CRL for PKINIT, PKINIT fails and krb5kdc service crashes. Version-Release number of selected component (if applicable): krb5-pkinit-openssl-1.7.1-2.fc12.x86_64 How reproducible: Always Steps to Reproduce: 1. Configure KDC and clients to verify CRL for PKINIT. 2. Execute kinit on the client Actual results: 1. kinit fails to get kerberos ticket 2. krb5kdc service crashes on the server 3. krb5kdc.log contains following records Mar 16 23:09:36 kerberos.xxx krb5kdc[6717](info): AS_REQ (7 etypes {18 17 16 23 1 3 2}) xxx.xxx.xxx.xxx: NEEDED_PREAUTH: user@realm for krbtgt/realm@realm, Additional pre-authentication required Mar 16 23:09:36 kerberos.xxx krb5kdc[6717](info): preauth (pkinit) verify failure: Different CRL scope Mar 16 23:09:36 kerberos.xxx krb5kdc[6717](info): AS_REQ (7 etypes {18 17 16 23 1 3 2}) xxx.xxx.xxx.xxx: PREAUTH_FAILED: user@realm for krbtgt/realm@realm, Different CRL scope Expected results: Kinit should succeed. Additional info: CRL is up to date and looks fine. It is produced by dogtag CA and works for other services, e.g. apache httpd. The problem have appeared after upgrading to Fedora 12, exactly the same configuration in Fedora 11 works fine. Disabling CRL verification in kdc.conf and krb5.conf is the only workaround I was able to find.
