Fixed In Version:	krb5-1.12.2-7.el7
Doc Type:	Enhancement
Doc Text:	Feature: Support for contacting KDCs and kpasswd servers via HTTPS proxies which implement the KKDCP protocol has been backported. Reason: The Kerberos client libraries could not communicate with KDCs or kpasswd servers in environments where realm services were only accessible via a KKDCP proxy. Result: When a realm's configuration specifies a realm's KDC's or kpasswd server's location in the form of an HTTPS URI, the Kerberos client library will now use KKDCP to communicate with the server.

Description Nalin Dahyabhai 2014-06-16 11:45:28 EDT

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.
