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 David Mulford 2018-04-13 15:21:16 UTC 
mod_auth_gssapi reports the following log message as an error.

[auth_gssapi:error]  NO AUTH DATA Client did not send any authentication headers

Upstream has downgraded this to an INFO message.

GitHub Issue: https://github.com/modauthgssapi/mod_auth_gssapi/issues/155
Commit: https://github.com/modauthgssapi/mod_auth_gssapi/commit/07b0d3c568b8086fcf1558e9b1745df99bb15081

This is causing the error log to become flooded with these log messages making it difficult to find any actual errors that may be happening.


Version-Release number of selected component (if applicable):
- httpd-2.4.6-67.el7_4.6.x86_64
- mod_auth_gssapi

How reproducible:
Always


Steps to Reproduce:
1. Install httpd and mod_auth_gssapi packages
2. Configure auth_gssapi for Kerberos auth
3. View the httpd error logs

Actual results:
Errors logs flooded with the log messages.

Expected results:
Logs should not be flooded with the log messages when LogLevel is set to warn.
