This person was able to setup autofs with sssd and samba as their AD server.
I haven't tried this, but in theory if you make the right settings in MS AD and in the config files for autofs and sssd, it should work pretty much the same.
Since you have to specify where the ou for the automount base is in the autofs config files, you don't actually need to make the automount ou at the base level, but it's up to you and your ad structure on where you want to put it. Then as long as you have krb5, ldap, and everything set right, it should work for
