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
