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 Geetika Kapoor 2017-10-03 06:47:25 UTC

Description of problem:

Looking for better logging for detecting issue faster.Audit and debug doesn't have much information to troubleshoot the issue. As a user they mind need it.

1. If we are trying to sign a SubCA certificate using a non Agent certificate it fails with 

<debug logs>
[03/Oct/2017:02:29:50][http-bio-8443-exec-23]: ProfileSubmitCMCServlet: authenticate: Invalid Credential.
[03/Oct/2017:02:29:50][http-bio-8443-exec-23]: SignedAuditEventFactory: create() message created for eventType=AUTH_FAIL
</debug logs>

2. Audit logs doesn't provide exact failure reason:

<audit logs>

</audit logs>


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

rpm -qa pki-ca
pki-ca-10.4.1-15.el7_4.noarch

How reproducible:

always

Steps to Reproduce:
1.Try to sign a SubCA certificate with a user certificate
2.
3.

Actual results:

Reason of failure is never listed in logs.

Expected results:

Reason should be visible in logs .
example: user certificate not have permissions to sign a subCA certificate

Comment 2 Geetika Kapoor 2017-10-03 07:03:08 UTC

Test Case 2: I tried to add this certificate as part of CA's Agent group using:

pki -d . -c SECret.123 -n "PKI CA Administrator" ca-user-cert-add test108 --serial 0x1f6fd129
pki -d . -c SECret.123 -n "PKI CA Administrator" ca-group-member-add "Certificate Manager Agents" test108
pki -d . -c SECret.123 -n "PKI CA Administrator" ca-group-member-find "Certificate Manager Agents"
-----------------
3 entries matched
-----------------
  User: caadmin

  User: pkidbuser

  User: test108
----------------------------
Number of entries returned 3
----------------------------

Later I execute the same test for SubCA i got a NUllPointerException:

<Debug logs>

Comment 4 Christina Fu 2017-10-11 21:20:33 UTC

The following are results of my investigation.

for the initially reported issue, there is adequate info in the debug log:

[11/Oct/2017:14:04:31][http-bio-8443-exec-22]: CertUserDBAuthentication: cannot map certificate to any userUser not found
[11/Oct/2017:14:04:31][http-bio-8443-exec-22]: CMCAuth: Invalid Credential.
[11/Oct/2017:14:04:31][http-bio-8443-exec-22]: SignedAuditLogger: event CMC_SIGNED_REQUEST_SIG_VERIFY
[11/Oct/2017:14:04:31][http-bio-8443-exec-22]: SignedAuditLogger: event CMC_SIGNED_REQUEST_SIG_VERIFY

For the issue reported in comment #2 on NPE for once a user cert is added to agent group, I was able to reproduce the issue, so this needs to be fixed.
I think it has the same issue as the one reported earlier on user signed CMC auth for "missing CN".
