Actually that isn't a bug. It's the default setup for uaio.
To change that so public users can't vote is to change this in the file
uaio_groups.ini:
Code:
;---------------------------------------------------------------------------------------
; Groups for Vote-Command Access
;---------------------------------------------------------------------------------------
group "grp_vote_public" "vote" "abcdf"
Change to:
Code:
;---------------------------------------------------------------------------------------
; Groups for Vote-Command Access
;---------------------------------------------------------------------------------------
group "grp_vote_public" "vote" ""
Save it, restart server, and no one should be able to access voting unless you are an admin.
