access control to trixbox portal

Hi,

In free PBX, I have created a user and just given him access to 'conferences' and 'ivr'. It works fine if I log in to the 'PBX Settings' drop down on PBX menu on the trixbox portal. i.e.: http://
/maint/index.php?freepbx.

However, this way the user could also access many of the other 'administrative' functions from the portal e.g. 'Config file editor'

Is it possible to give access to just the PBX features the administrator allows (e.g. ivr and conferences, in this case) and nothing else?

I tried http://
/freepbx. but that doesn't work

basically, for the user I create using PBX->PBX Settings->Administrators->Add user, I would like to lock down access to features only permitted in 'Admin access' rules

Thanks,
