Yes, pam_ldap supports enforcing the password policy probably by correcty
handling the response controls. Grepping through the source of recent versions
it seems to me it does not read attribute pwdChangedTime nor does nss_ldap.

AFAICS nss_ldap cannot deliver the correct value for 'shadowLastChange' when
someone or something invokes a call like this

getent shadow michael

'pwdChangedTime' is of syntax Generalized Time whereas 'shadowLastChange' is
Integer with seconds since epoch. In theory nss_ldap could convert it. But
AFAICs it doesn't. Also if an older client would search for
(shadowLastChange<=<value>) this wouldn't work either.

Well, you're the OpenLDAP boss and free to refuse anything you want. But
personally I don't understand your strong objections.

Ciao, Michael.
