This field is the basis of the errata or release note for this bug. It can also be used for change logs.
The Technical Note template, known as CCFR, is as follows:
The kprop/kpropd pair of tools did not support IPv6 connections.
If a master KDC could not reach a replica using IPv4, realm databases could not be propagated, even on networks where both master and replica were configured to use IPv6.
Portions of kprop and kpropd were modified to take advantage of dual-stack support provided by the operating system.
