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.

Description Kaushik Banerjee 2014-04-18 11:00:17 UTC

Description of problem:
User with expired shadow policy is not prompted for password change when shadowLastChange is 0

Version-Release number of selected component (if applicable):
sssd-1.11.2-65.el7

How reproducible:
Always

Steps to Reproduce:
1. Disable any server side password policies.
2. Set ldap_pwd_policy = shadow in sssd.conf
[domain/LDAP]
debug_level = 0xFFF0
id_provider = ldap
ldap_uri = ldap://<ldapserver>
ldap_tls_cacert = /etc/openldap/certs/cacert.asc
ldap_search_base = dc=example,dc=com
ldap_pwd_policy = shadow

3. Set shadowLastChange to 0 in the user ldap attribute.
# ldapsearch -x -LLL -h <ldapserver> -b "dc=example,dc=com" uid=shadowuser1
dn: uid=shadowuser1,ou=People,dc=example,dc=com
uid: shadowuser1
cn: shadowuser1
objectClass: posixAccount
objectClass: top
objectClass: shadowAccount
shadowLastChange: 0
shadowMin: 0
shadowMax: 99999
shadowWarning: 7
loginShell: /bin/bash
uidNumber: 9901
gidNumber: 9901
homeDirectory: /home/shadowuser1

4. Auth as the user
# ssh -l shadowuser1 localhost
shadowuser1@localhost's password: 
Permission denied, please try again.
shadowuser1@localhost's password:


Actual results:
Password change prompt does not appear.
/var/log/sssd/sssd_LDAP.log shows:
(Fri Apr 18 06:35:22 2014) [sssd[be[LDAP]]] [find_password_expiration_attributes] (0x4000): Found shadow password expiration attributes.
..
(Fri Apr 18 06:35:22 2014) [sssd[be[LDAP]]] [check_pwexpire_shadow] (0x0100): Last change day is not set, new password needed.
(Fri Apr 18 06:35:22 2014) [sssd[be[LDAP]]] [sdap_pam_auth_done] (0x0020): check_pwexpire_shadow failed.


/var/log/secure shows:
Apr 18 06:35:22 beast sshd[18105]: pam_sss(sshd:auth): received for user shadowuser1: 4 (System error)

Expected results:
Password change prompt should appear.

Additional info:
With server side password policies enabled, the following is seen:
# ssh -l shadowuser1 localhost
shadowuser1@localhost's password: 
Your password has expired. You have 1 grace login(s) remaining.
[shadowuser1@ibm-z10-51 ~]$

Comment 3 Kaushik Banerjee 2014-06-13 09:07:39 UTC

This looks like a regression in 1.11 version of sssd.

I tried this on rhel6.5 and saw the password prompt appearing:
#  ssh -l shadowuser1 localhost
shadowuser1@localhost's password: 
Password expired. Change your password now.
WARNING: Your password has expired.
You must change your password now and login again!
Changing password for user shadowuser1.
Current Password:
