You mean something like this?
```
# rpm -qf /etc/krb5.conf.d/fedoraproject_org
fedora-packager-0.5.10.7-4.fc26.noarch
# cat /etc/krb5.conf.d/fedoraproject_org
[realms]
FEDORAPROJECT.ORG = {
kdc = https://id.fedoraproject.org/KdcProxy

[domain_realm]
.fedoraproject.org = FEDORAPROJECT.ORG
fedoraproject.org = FEDORAPROJECT.ORG
```
