RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Text:
This field is the basis of the errata or release note for this bug. It can also be used for change logs. The Technical Note template, known as CCFR, is as follows: Cause When reading a principal entry from a directory server, the LDAP kdb plugin would fail to correctly heed of an explicit password expiration time stored in the principal entry. Consequence If a password lifetime was set as part of a password aging policy which applied to the entry, then any password expiration time stored in the principal entry itself would be ignored in favor of the value calculated based on policy's password lifetime and the date the entry's password was last changed.

Description Nalin Dahyabhai 2010-08-24 22:10:41 UTC 
+++ This bug was initially created as a clone of Bug #627022 +++

Description of problem:

There are two occurences of this line in src/plugins/kdb/ldap/libkdb_ldap/ldap_misc.c lines 2085 and 2142:

    if ((mask & KDB_PRINC_EXPIRE_TIME_ATTR) == 1) {

KDB_PRINC_EXPIRE_TIME_ATTR is defined as 0x80, it will never == 1.

This is causing the krbPwdExpiration attribute to be ignored.

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

krb5-server-1.8.2-3.fc14.x86_64
