CrAcKeR : have u tried to login with that user manually, with telnet from windows ?
VaNisH : i actually never tought about that, shame on me
will fix a 'group' setting in next version (probably tonight).
i think that i'll split this program in 2 parts: the one u see now, and a "local" GUI front-end, that edits the user/group files itself (will only work on the machine ioFTPD is running on)
