dereference wi= th the LDAP kdb backend (CVE-2011-1527, #744125), an
assertion failure with= multiple kdb backends (CVE-2011-1528), and a
NULL pointer dereference with= multiple kdb backends (CVE-2011-1529).
(#737711)

It also rolls up a number of mostly-minor fixes, some of which were
backpor= ted from upstream to the Fedora 16 branch. The main
user-visible change is= a fix for cross-realm authentication in the
client libraries.
