Can you talk more about how you chose the users that needed password expiration, and how often this needs to happen?

It seems like simply adding the password expiration to the multi-select options would be a big improvement, but I want to make sure we're addressing the right use case.

One workaround to accomplish this for all users is to modify the general password setting for password modification and set it to a very short period:

Make sure to change this back to your previous setting after the time has passed to expire users' passwords.

If you want a way to set it immediately, you can directly modify the SQL database to expire all user passwords. Please backup your database before making any changes.

  update [yourdatabasename].[dbo].[directory_objects] 
  set password_uses_left = '0'
  where type = '0' and provider_id is NULL

Type = '0' will exclude groups (type 1) and organizations (type 3), while a NULL provider_id will exclude Windows, SAML, and LDAP user types, leaving you only with Laserfiche users.
