Note that this has a slight behavior change to c89d3f3b in order to continue
allow kadmin in local mode to bypass password quality checks. Password quality
checks are always bypassed if the *client* kadmin principal is kadmin/admin,
i.e. that of the kadmin service itself. This is the case when running kadmin in
local mode. As this is the equivalent of a superuser account, one would
anticipate that deployments would use specific administrator instances for
appropriate ACLs for day-to-day administration; operations by these will be
subject to password quality checks if enforce_on_admin_set is TRUE, or if the
user is changing their own password.
Fix a regression introduced in c89d3f3b where administrative password changes
would be logged as user password changes, if enforce_on_admin_set was set.
This patch adds the "enforce_on_admin_set" configuration knob in the
[password_quality] section. When this is enabled, administrative password
changes via the kadmin or kpasswd protocols will be subject to password quality
checks. (An administrative password change is one where the authenticating
principal is different to the principal whose password is being changed.)
Note that kadmin running in local mode (-l) is unaffected by this patch.
In verify() if krb5_unparse_name() fails 'sname' will be used
unitialized in the subsequent krb5_warnx() and free() calls.

Tests that start daemons have to "wait" for them to start.
This commit makes Heimdal daemons prep to detach (when requested) by
forking early, then having the child signal readiness to the parent when
the child really is ready. The parent exits only which the child is
ready. This means that tests will no longer need to wait for daemons.
However, tests will still need a pidfile or such so they can stop the
daemons.
Note that the --detach options should not be used on OS X from launchd,
only from tests.
We turn on a few extra warnings and fix the fallout that occurs
when building with --enable-developer. Note that we get different
warnings on different machines and so this will be a work in
progress. So far, we have built on NetBSD/amd64 5.99.64 (which
uses gcc 4.5.3) and Ubuntu 10.04.3 LTS (which uses gcc 4.4.3).
Notably, we fixed
1. a lot of missing structure initialisers,
2. unchecked return values for functions that glibc
marks as __attribute__((warn-unused-result)),
3. made minor modifications to slc and asn1_compile
which can generate code which generates warnings,
and
4. a few stragglers here and there.
We turned off the extended warnings for many programs in appl/ as
they are nearing the end of their useful lifetime, e.g. rsh, rcp,
popper, ftp and telnet.
Interestingly, glibc's strncmp() macro needed to be worked around
whereas the function calls did not.
We have not yet tried this on 32 bit platforms, so there will be
a few more warnings when we do.
Only send an error reply if the request passes basic verification.
Otherwise, kpasswdd would reply to every UDP packet, allowing an
attacker to set up a ping-pong DoS attack via a spoofed UDP packet with
a source address of another UDP service that also replies to every
packet.
Also suppress the error reply if ap_req_len is 0, since this indicates
an error packet. An error packet may be the result of a ping-pong
attacker pointing us at another kpasswdd.
