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 of problem:
With an IPA client configured for Smart Card authentication, we are seeing issues with SSH:
# ssh -I /usr/lib64/opensc-pkcs11.so -l ipauser1 localhost whoami
sign_and_send_pubkey: signing failed for RSA "pkcs11:?module-path=/usr/lib64/opensc-pkcs11.so": error in libcrypto
Version-Release number of selected component (if applicable):
openssh-server-8.7p1-30.el9.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Configure IPA environment for smart card authentication
2. ssh -I /usr/lib64/opensc-pkcs11.so -l ipauser1 localhost
Actual results:
fails to prompt for PIN and returns error seen above.
Expected results:
Prompts for PIN and logs user into remote system.
Additional info:
Thanks for the logs. From the pkcs11 spy, it is visible only that the keys are listed correctly, but after that, OpenSSH does not continue to the `C_Login()` for some reason.
So we will need some more debugging inside of OpenSSH to figure out why it fails to sign using pkcs11-provided key as it never reaches the OpenSC.
