IPA automount stopped working after recent RH9 autofs update

Hi,
I just recently experienced some trouble with some RH9 machines failing to automount some NFS volumes on boot with v4.2,sec=krb5,seclablel auto.direct options that were previously working. I am able to mount the volumes manually after the fact, so the server seems ok. Downgrading autofs from 5.1.7.31 -> 5.1.7.27 restores functionality. According to rumblings and murmurings on the internet, there's a bug that appears to have resurfaced that attempts to use rpcbind, even though nfs4 is not supposed to use it.
