No you cannot. But that is new information so my previous replies do not apply to your situation (it's always better to give those details from the start in your Original Post, makes discussions shorter and more to the point)
Custom directory operates its own list of user definitions which can only be managed from inside the QMC or from custom applications. You cannot mix Custom Directory with AD or any standard premission system like NTFS, simply because for example Custom Directory users do not exist in NTFS or AD. They only exist inside QlikView.
Actually, I think you answered your own question here (last sentence): Re: Can I restrict user password or give a warning for changing the password every 30 days?
You should indeed talk to your web developer. One big advantage of a system like Custom Directory is that you can extend it yourself. However, to do that you'll need someone with web programming experience, like you said yourself.
Custom Directory users are defined in an xml file called C:\ProgramData\QlikTech\DirectoryServiceConnector\CustomDirectoryData.xml. There is no tag that stores the timestamp of definition or last password change, but that can be compensated by either requesting password changes on a fixed date (for example, every first of the month) or by storing password expiry dates in a new xml file and letting the login page handle the data from these two.
Best,
Peter
