The same container image that can run HTTPD using Kerberos to authenticate in Podman can be used to do the same thing in OpenShift. Here’s the changes

Developers may want to make their applications work with Kerberos while developing inside containers. Here is a quick proof-of-concept that shows how to set up a container to work with mod_auth_gssapi., the Apache module that makes use of Kerberos.
