restricted ftp-only accounts on Solaris 7?

[John LLOYD <jal@mda.ca>]

How can I create or arrange for accounts allowing only ftp access to a
certain set of directories?  Note that anonymous is insufficient; we want
password authentication to be used, but we want the other features of
"anonymous ftp" like chrooted directory, short list of authorized users
independant of /etc/passwd, logging too.

Solaris 7 man ftpd shows a script to set this up (using native ftpd) but it
seems to allow only for anonymous ftp.


Choices so far:  

a) shell command that does a logout (ensures only ftp access, but leaves the
user free to cd all over)
b) fiddle with the Solaris script to see if anonymous can be turned off
c) some sort of front end to the anonymous ftp to check a password 


And, did I mention I need this working by Friday?

Any ideas?

Cheers
