The default libkadm5clnt library on the system must match the
implementation of your KDC for the module/expired test to work, since the
two kadmin protocols are not compatible.  If you use the MIT library
against a Heimdal server, the test will be skipped; if you use the Heimdal
library against an MIT server, the test suite may hang.

Several `module/expired` tests are expected to fail with Heimdal 1.5 due
to a bug in Heimdal with reauthenticating immediately after a
library-mediated password change of an expired password.  This is fixed in
later releases of Heimdal.

To run the full test suite, Perl 5.8 or later is required.  The following
additional Perl modules will be used if present:

* Test::Pod
* Test::Spelling

All are available on CPAN.  Those tests will be skipped if the modules are
not available.
