This bug was fixed in release 1.21 by
commit 29600cf1db888d91c42cbd6cf72652afe8c1ee66 (ticket 9071, https://
github.com/krb5/krb5/pull/1266 ).  The problem was the use of a signed 32-bit
value to hold the interval.

(It would of course be nice if Microsoft's Kerberos implementation didn't use
arbitrary dates in the far future when it means "never".  A KDC can simply not
transmit a password expiration time.)
