No worries.  It may have been happened in a private email, I think we've
exchanged a few of those.

Given the configuration file you listed, I'd suspect a network timeout
in the account management check (either attempting to resolve the KDC's
host name, or in contacting the KDC).

Disabling such a check adds the risk of not denying access to someone
for whom access should be denied, so that's not something I can
recommend as a general solution -- unlike the authentication check,
where any module can give the user a thumbs-up, for account management
you need for any module to be able to torpedo the user's login attempt.

The timeouts in libkrb5 aren't adjustable, either, at least not if
you're playing by the rules (and maybe not at all in 1.3 -- I last
looked at this part of it in 1.2), so I don't really have a good answer
for this problem.
