SFTP through proftpd

[Curtis Vaughan <curtis@npc-usa.com>]

I have set up proftp and it works great.  Now I want to make sure that 
proftp is used for sftp.  However, whenever I try to sftp into the 
server, sftp-server answers, which is part of the OpenSSH package.  
What do I need to do in order to get either sftp-server to hand over to 
proftp or just shut of sftp-server and have proftp handle the sftp 
requests?
