Using rbash (bash -r)

Trying to set up a restriced shell for a user. Basically they should be able to ls/cp/rm inside a chroot.

The one problem I am having is granting them permissions to the commands in the bash -r shell. From the man page "It behaves identically to bash with the exception that the following are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV"

Which led me to believe that if I set the PATH when logging in I could give them the access to them. But it doesn't work. There isn't too much out there on this - does anybody have any ideas????
