I never said it wasn't solid (possibly because it it is built on top of 
some of the winbind code), I just said that you do not need it.

Funnily enough, you can do all of the above with winbind.

You mean something like this:

getent group Domain\ Users

If it didn't work for you, then your smb.conf was mis-configured.

That just basically says 'Hey, use our product', it doesn't really say 
why and just how sssd is better than winbind.

You do not need either sssd or realmd, just about the only thing that 
sssd can do that winbind cannot do, is cache sudo rules, I think you 
will find that if you need cached sudo rules, you have much bigger 
problems. As for realmd, a bit of bash and 'net ads join' will do the same.

But hey, it is your computer, you use what you want, just don't expect 
to get help with non Samba products here.
