There you are getting into the LDAP/Kerberos territory or you can use winbind.
In theory if you install the UNIX extensions in your AD server you can
assign the users uid and gid numbers. last I looked at it you had to
do it manually they aren't auto assigned by the AD server.

You should also look at the documentation for sssd as well.

It's been a quite a few years since I did this but I think you will
have to create a kerberos keytab and Kerberos auth for the host for
the CIFS automount to work properly.
The other option is to use the NFS server for windows but I don't
advise using it on older versions of Windows Server.
