If your user is only going to be using SFTP and not require access to your box via SSH, you can set their "shell" to "/usr/sbin/sftp-server". The /usr/sbin/sftp-server is part of the SSH fileset included with AIX I believe. I've done this for quite a few users who will never login via SSH, they are just allowed to upload code. It even supports SSH key authentication. It isn't a big deal but it makes your box better secured.
Also, if you do decide to use it, make sure "/usr/sbin/sftp-server" is included on the "shells = ..." line in your /etc/security/login.cfg file, otherwise, it won't work.
