Effective attraction between like-charged walls mediated by counterions isstudied using local molecular field (LMF) theory. Monte Carlo simulations ofthe "mimic system'' given by LMF theory, with short-ranged "Coulomb core"interactions in an effective single particle potential incorporating amean-field average of the long-ranged Coulomb interactions, provide a directtest of the theory, and are in excellent agreement with more complexsimulations of the full Coulomb system by Moreira and Netz [Eur. Phys. J. E 8,33 (2002)]. A simple, generally-applicable criterion to determine theconsistency parameter sigma_{min} needed for accurate use of the LMF theory ispresented.
