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: coolkey-1.1.0-38.el6
Doc Type: Bug Fix
Doc Text:
Cause: The coolkey update in RHEL 6.8 updated the coolkey cache file format, but did not rename the cache file. Consequence: If the new coolkey started with an old cache file it could become confused. Fix: Removing the cache file would clear the old error. Coolkey has benn updated in RHEL 6.9 to use a new name for the cache file so updating coolkey will also solve the issue.

Description Chinmay Paradkar 2016-07-19 21:47:30 UTC 
Description of problem:
Upgrading from coolkey 1.1.0-35 to 1.1.0-37 breaks smart card functionality for sudo functionality and screensaver unlock.  

With coolkey 1.1.0.35 users can login to gnome, open a terminal session and use sudo -i which then prompts the user for the smart card pin to use those credentials to authorize sudo.  

After upgrading to coolkey 1.1.0-37 the sudo command displays the prompt 'Please insert your smart card called "FIRST.LAST.EDIPI"' and freezes there.   additional functionality regarding the gnome screensaver and unlocking with smart cards also fails.

Version-Release number of selected component (if applicable):
coolkey-1.1.0-37

How reproducible:
Always

Steps to Reproduce:
1. Standard setup.
2.
3.

Actual results:
Failure

Expected results:
Work as expected

Additional info:
This appears to be caused by a change in how the coolkey libraries acces files under /var/cache/coolkey. Both versions have the files under this directory with permissions of 600 owner root groupowner of the user. 

Workaround for coolkey 1.1.0-37 is chowning the user's file from root to the user in question fixes the issues.
Comment 4 Matt Titus 2016-09-19 13:04:37 UTC 
It appears this extends to gnome based applications which require smart card support as well (IE: Firefox and SmartCard Manager) though only for UID 500 on a fresh installation.  Interestingly enough aside from the broken sudo & su behavior all other pcks11_* testing works as intended.

How reproducible:
Always

Steps to reproduce:
1.  Install OS with 'Basic Desktop'
2.  Install pcsc-lite coolkey and escd
3.  Configure Security device in firefox
3.  Insert SmartCard

Actual results:
No notification that SmartCard is inserted via SmartCard Manager, nor do PKI websites work inside of firefox and the reading of the security device in FireFox fails.

Expected Results:
SmartCard Manager would notify the SmartCard was inserted, Firefox should be able to view details of the card in the security device.

Workaround:
The workaround listed above by altering the ownership of the /var/cache/coolkey file for the user in question corrects this behavior.
Comment 5 Bob Relyea 2016-10-03 22:50:58 UTC 
I think this is a problem between the old and new cache values. When you read a card with an old (pre- coolkey-36) cache value coolkey will fail. I'll patch -38 with code that will use a new name for the new cache value to fix this.

In the meantime you can fix the issue by removing /var/cache/coolkey/*.

Noticed the following:

1. Add the kerberos user to /etc/sudoers file as follows

root    ALL=(ALL)       ALL
kdcuser2        ALL=(ALL)       ALL

2. Reboot the client and attempt smartcard login. Login fails the following are the log messages

I am not sure what exactly is causing this issue. Because I do see the same even after removing kerberos user from the sudoers file. But after multiple restarts the smartcard login is successful.
Comment 9 Roshni 2016-11-30 15:46:14 UTC 
Adding TestBlocker because of the issue explained in comment 8, I am unable to do further testing using smartcards unless the OS is re-installed.
Comment 10 Bob Relyea 2016-12-13 02:09:14 UTC 
So I've tried this on my machine, and I'm able to add my user to sudo list and still log in. The difference is I'm using cn= not kerberos. I think I'll have to look at your machine to see what is going on.

2. Login using smartcard with the kerberos user

3. 
sh-4.1$ sudo yum -y install gcc
Found the Smart card.
