[Bug 571572] Re: krb5 prefers the reverse pointer no matter what for locating service tickets.

[Tom Yu]

Recent discussion on #krbdev suggests that this is actually (in part) a
glibc bug in getaddinfo(). With ai_flags=AI_CANONNAME and
ai_family=AF_INET, getaddrinfo() performs a PTR lookup anyway (contrary
to POSIX), effectively preventing a setting of rdns=false from being
effective. We have a workaround for the glibc bug upstream at
