Kerberos allows the autodiscovery of realm via setting the krb5.conf option dns_lookup_realm. We should have a similar option in SSSD.

We have decided that this feature is potentially dangerous as it allows the client to be presented with arbitrary realm with spoofed DNS replies. We will defer it until it is requested. In the mean time, the WIP code is in my personal git repository on fedorapeople, so we can always resume from there.

This would be a useful feature for me - do the security concerns also exist when using the krb5.conf option?

Replying to [comment:3 danieljamesscott]:

According to nalin kerberos libraries are smart enough to negotiate the right ticket securely using cross realm referrals without relying on the TXT records.

It might not make sense to add this functionality ever.
Putting in Differed for now.

Thank you for taking time to submit this request for SSSD. Unfortunately this issue was not given priority and the team lacks the capacity to work on it at this time.

Given that we are unable to fulfill this request I am closing the issue as wontfix.

If the issue still persist on recent SSSD you can request re-consideration of this decision by reopening this issue. Please provide additional technical details about its importance to you.

Thank you for understanding.
