You can set various attributes in AD, amongst which is one called
'homeDrive', this is the AD equivalent of 'logon drive' and allows
you to set different drive letters per user.

Probably very similarly to what you are doing now, except that you can
use PAM to create the users home directory (pam_mkhomedir)

You do not use the ldap backend on Unix domain members and you do not
need sssd, Samba can do virtually all that sssd can do. Try reading
You can still use ldap against Samba AD, but there are possibly better
ways of doing things, depending on just what you are trying to
authenticate against AD.

You do not use either of those, you just use the AD password.

Try reading this:
I would however recommend changing the ID's (if possible) before the
migration, they will undoubtedly be based on the RIDs i.e. very low
numbers such as '1000' and these will interfere with the local Unix

I am sure they will ;-)
