You can also use the SHUN command.

Usage:  shun src_ip [dst_ip sport dport [prot]]
        no shun src_ip
        show shun [src_ip|statistics]
        clear shun [statistics]

Hi

I don't know about Cisco Pix.
But one ide that hit me that might work as an alternative solution.
Is to make a null route to the IP address of the user you no longer 
approve to be connected.
And when the connection is dropped remove the null route

It is not the right way but I think it will get the job done?
