Thank you for your answer. I am asking because at the moment I don't  
have a spare machine to test it.

Of course you did include "-winbind +winbindd" in a "server services"  
line in smb.conf, didn't you?

Well, my systems work well as they are, with backend RID on member  
servers only. I suppose I wanted to unify the whole thing for a  
question of elegance only. Given that versions 4.2.x can use the  
normal winbind on a DC, I expected consistent behavior here.
