#481 [RFE] autodiscover Kerberos domain through TXT records
Closed: wontfix 3 years ago by pbrezina. Opened 13 years ago by jhrozek.

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


Fields changed

component: SSSD => Kerberos Provider
milestone: NEEDS_TRIAGE => SSSD 1.3.0

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.

milestone: SSSD 1.3.0 => SSSD Deferred

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

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.
