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.

Comment 2 Jakub Jelen 2018-04-26 08:44:33 UTC 
This was mostly discussed in the upstream issue [1] and also in previous bug #1449740 (fixed in RHEL7.5), where we were trying to match both PIV specification and coolkey-like behavior.

Lets start with PIV specification to clarify why we do that. The PIV cards can have two PINs and internal structures in the card specify what PIN the user should be asked for. Therefore it makes sense to present this information also to the user. On the other hand, really, most of the users with PIV cards will have selected the first PIN and they will never see the "Global PIN" label.

Before RHEL7.5 (#1449740), OpenSC was showing only the PIN type:

token label        : PIV Card Holder pin (PIV_II)
token label        : Global PIN (PIV_II)

From RHEL7.5, we added a cardholder identification from certificates on the card so the possible PINs have the following structure:

  token label        : Test Cardholder X
  token label        : Global PIN (Test Cardholder VII)

The important thing here is that only SOME [2] of the testing cards require the Global PIN and therefore they have modified the label to indicate it. This was perceived by Roshni as an inconsistency (?) and therefore we decided to open this low-priority bug to revisit the issue for the next release.

For me, this is still not a bug, but a feature. But I am open for discussion if you believe otherwise.

Comment 3 Roshni 2018-05-07 17:07:33 UTC 
I agree with Jakub that this was a very minor difference from coolkey behavior. I will go ahead and close this bug because of the reason.
