The functionality that you require is not yet available in Adaxes, but it will be released in the nearest version that is planned for next month.
However, if you need the functionality urgently, we can suggest a workaround. You can create a Business Rule that will be executed after resetting the password for a user. The Business Rule will set the User must change password at next logon option for the user to true, and the User cannot change password and Password never expires options to false for the user regardless of what was selected on the Reset Password page. The only issue here is that it is currently impossible to remove the checkboxes from that page, this functionality will be available in the next version. Also, it will be impossible to detect, where the Reset Password operation was performed, so the Business Rule will set the default values for users even if the password was reset from the Web Interface for Administrators or even from the Administration Console. If this solution is OK with you, we can provide you with details.
