LDAP (POSIX attibutes) password expiry

Hi:
We've been running various versions of FreeRadius for years, currently 2.1.10 in
this application. A while ago, we switched from PAM (unix) auth to LDAP auth.
Everything worked fine after the switch...POSIX attributes for group membership
correctly allocated the right ippools, etc.
However, we just noticed that password expiry isn't working. I suspect this is
because we are still using all the original POSIX attributes and none of them look
like good for mapping to the ones supplied by FreeRADIUS. I see:
checkItem Expiration radiusExpiration
Our LDAP attributes use the following POSIX attributes to determine expiry:
shadowMax: 90
shadowLastChange: 15215
With the first being the maximum age of the password and the second being the
number of days since the Epoch. I will post the obligatory debug output below
(with sensitive or irrelevant stuff snipped out) for a successful authentication
for an expired password that shouldn't have succeeded. If anybody has an idea how
to fix this with the minimal of messing around with our LDAP config itself, I'd
greatly appreciate it...or, if that's unrealistic, what should be done. TIA!
