RBAC with ftp/sftp using proftpd

I'm using proftpd to manage my ftp/sftp connections but would like to use RBAC to only allow ftp/sftp connections. Has anyone done this or can point me in the right direction? This is my first experience trying to use RBAC. Thanks in advance.

I think you want to use "ipfilter" - Solaris firewall. RBAC is used to delegate administration tasks to different users.

What I'm trying to do is block users from being able to ssh in when they come in over port 22. I actually have it somewhat blocked with proftpd by having ssh and proftpd listening on different IPs.
