Red Hat Bugzilla – Bug 861091
pam_sss report System Error on wrong password
Last modified: 2013-06-03 10:24:12 EDT
This bug is created as a clone of upstream ticket: https://fedorahosted.org/sssd/ticket/1515 krb5_child transforms Kerberos return codes into PAM return codes using a switch statement. That statement never matched the error code for wrong password and returned with generic System Error. While the access is correctly denied, this may result in annoying false positives and perhaps even issues with the rest of the PAM stack. Reported by Joschi Brauchle in the [https://bugzilla.novell.com/show_bug.cgi?GoAheadAndLogIn=1&id=779246 Novel bugzilla] and on the [https://lists.fedorahosted.org/pipermail/sssd-users/2012-September/000166.html sssd-users-list]
Verified the BZ on SSSD version: sssd-1.9.2-41.el6.x86_64 Reproduced the bug on older build and automated the steps to verify the presence of System error in log file.
