[SSSD-users] Only IPv4 addresses in /var/lib/sss/pubconf/kdcinfo.DOMAIN

On my dual-stack network where some machines actually don't have IPv4 connectivity I am finding that whatever is writing IP addresses into /var/lib/sss/pubconf/kdcinfo.DOMAIN is only writing the IPv4 addresses and not the KDC's IPv6 addresses.

The result is that such an IPv6 machine cannot reach a KDC until I remove that file. It ends up being recreated at some subsequent point again with only the KDC's IPv4 addresses.

Is this a bug or a problem with my configuration?

Cheers, b.
