hello all
Sorry for the delay in the response
I checked the ppolicy overlay but without success. This overlay does not have a
single "password expired" attribute to put in the user_filter.

currently my dovecot-ldap.conf contain:

user_filter (&(|( = uid =% u) (employeeNumber =% u)) (objectClass =
inetOrgPerson) (accountStatus = active))

is possible that the only way to do this is to manage a new attribute?  how can
understand  all the people that have configured the mail client to authenticate
with imap-dovecot that their passoword has expired?
