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:
We'd like for Kerberos clients to be able to access KDCs and password changing services over https proxies, via the [MS-KKDCP] support that's planned for krb5 1.13.  If we don't end up jumping to that in the next update, we're going to want to backport it.

Version-Release number of selected component (if applicable):
krb5-1.11.3-49.el7

How reproducible:
Always

Steps to Reproduce:
1. Stand up a Windows Server with the KDC Proxy Service running, or a web server with python kdcproxy.
2. Configure /etc/krb5.conf with 'kdc' and 'kpasswd_server' entries only in the form of https URLs and with the server's CA as a trusted anchor, either in the default locations or via explicit configuration.
3. Attempt each of 'kinit' (AS request), 'kvno' (TGS request), and 'kpasswd' (kpasswd request).

Actual results:
Each fails because the library doesn't know how to even parse HTTPS URLs, much less use them.

Expected results:
Each should succeed.
