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.

Fixed In Version: sssd-1.13.0-0.1.alpha.el7
Doc Type: Release Note
Doc Text:
Multi-step prompting for one-time and long-term passwords When using a one-time password (a token) together with a long-term password to log in, the user is prompted for both passwords separately. This results in better user experience when using one-time passwords as well as a safer long-term password extraction, which allows long-term password caching to be used for offline authentication.

Description Martin Kosek 2015-03-11 14:35:33 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/2335

Right now user is prompted for password and token code in one prompt. It makes it extremely hard to determine which part of the input is user password that can be cached locally for the offline use case and which part is the code. The feature would allow consulting Kerberos to determine how to properly prompt user.

Comment 4 Namita Soman 2015-09-22 02:36:49 UTC 
Verified using ipa-server-4.2.0-10.el7.x86_64

Added ipa user, assigned otp token, config'd user to auth using otp
Then auth'd this user using two factor auth:
# su - admin
su: warning: cannot change directory to /home/admin: No such file or directory

-bash-4.2$ su - one
First Factor: 
Second Factor: 
Last login: Mon Sep 21 21:57:50 EDT 2015 on pts/0

Verified even though login was at 22:16, old tkt was not refreshed since user is auth'ing offline

# ipactl start

Verified local user can still login as it would normally:
[root@dell-per320-01 ~]# useradd linuxuser1
[root@dell-per320-01 ~]# passwd linuxuser1

[linuxuser1@dell-per320-01 ~]$ su - admin
