Todd Lipcon commented on MAPREDUCE-2473:
----------------------------------------

It seems unfortunate that we're lumping in the "getGroups" API (an action 
intended for non-admin usage) with the refresh methods (admin actions). 
Unfortunately the ACLs for this whole Protocol are determined by 
"security.refresh.user.mappings.protocol.acl" which is a misnomer when it also 
affects the group command.

Any thoughts on a way around this?
