So it uses ~/ and %u here..

So home should be taken from NSS lookup..

This means the NSS lookup returned /home/NT-DOMAIN/user as the user's
home directory.

Are the users normally logging in as "user" or "NT-DOMAIN/user"? What
does it log with auth_debug=yes?

Anyway, this looks more like a configuration problem on your pam and
passwd (=NSS) side.
