Yes, I am aware of idmap_sss, but it isn't a Samba product, so we know 
nothing about it.

You should not run sssd and winbind on the same machine, sssd has its 
own versions of some of the winbind libs.

I repeat these truths, you should not run sssd and winbind on the same 
machine, but if you do, you should ask the sssd-users mailing list. This 
is because we do not produce sssd and know little or nothing about it.
