Your suggestions could be set out as:-
- Compare today's /etc/passwd to yesterday (sort first for ease)
- Save current /etc/passwd to use tomorrow
You can then look for password expiry based on the content of
/etc/security/password It's a little awkward because:-
- The Last password change time is stored in seconds from 1/1/1970
- The expiry will be in weeks, either per user or in the default stanza
Using
/etc/passwd as a driver, you can read one stanza from
/etc/security/passwd with
grep -Ep "^$userid:" /etc/security/passwd although you then have to consider the points above to decide if the password is about to expire, depending also how you define 'about to expire'
Does this give you something to work with?

partimaged-passwd
partimaged-passwd(8) Partition Image Server Configuration partimaged-passwd(8)
NAME
partimaged-passwd - Manage partimaged user accounts
SYNTAX
partimaged-passwd [-Dhl] username password
partimaged-passwd [-Dhl] username
DESCRIPTION
partimaged can either authenticate against local user accounts (This needs access to /etc/shadow. As this is a potential security risk this
method is not recommended) or its own password database in /etc/partimaged/passwd.db. To simplify the management of the partimaged user
database this tool was written. It allows to easily add and remove users or list the users in the database. All users in this database are
allowed to access the partimaged server.
OPTIONS
-D username
Delete the specified user from the password file.
-l List users in password file and exit.
-h Output help information and exit.
FILES
/etc/partimaged/passwd.db
