Anderson-darling test for discrete distribution fitting



Hello,
I was wondering if I can use AD as the GOF test for fitting discrete distribution? I have seen specific comments about not using Kolmogorov-Smirnov stat for this purpose, but haven't seen anything similar for AD stat. Any comment will be helpful.
Typical distributions I am trying to fit are binomial, poisson, geometric, hyper-geometric and negative binomial, if that matters.
Thanks.
