Comment 12 Adam Williamson 2014-10-21 22:48:00 UTC
I deployed the server and client from 21 Beta TC4 Server DVD, set up the server with rolectl deploy (with SELinux permissive to avoid various SELinux issues), then enrolled the client via Cockpit. Immediately thereafter named seemed to start crashing constantly on the server. Had to file the report from my desktop by copying the abrt problem directory off the VM because named just keeps crashing and prevent me reporting it from the VM itself.

Nominating as a Beta blocker per criterion "With the Domain Controller role active and correctly configured:

    Multiple clients must be able to enrol and unenrol in the domain
    Client systems must be able to authenticate users with Kerberos
    The FreeIPA configuration web UI must be available and allow at least basic configuration of user accounts and permissions "

if named is going to crash constantly after enrolling a client, those requirements and others are effectively broken for both the server and the client, because they can't resolve any names.

Comment 15 Adam Williamson 2014-10-22 21:02:30 UTC
Dropping the blocker nomination from this bug. It turns out the crash is in -2, which is not in stable, but rolekit is deploying the package from updates-testing during role deployment. We don't need to pull the fix into the Beta compose, we just need to make sure it's available to rolectl.
