[ubuntu-uk] Clever tricks using vsftpd virtual users to have seperate permissisons

[Matt Darcy]

Hi Ubuntu uk,

This is tricky subject to summerize. I'm pretty confident there isn't a
solution to do what I want, but I need a sounding board, so your it.

I'm looking at using vsftpd as an open ftp daemon, utilising the virtual
user functionality so I don't have to use genuine /etc/passwd or shell
based accounts.

The issue I've got is that I need multiple users (no problem so far) to
then have different read/write access to different directories under the
ftp root.

The virtual users have no awareness or interaction with the Unix file
system permissions, nor do they respect them as they work through the
ftpd process owning account.

I'm looking at clever ways to do this such as a permissions schema
linking into mysql, but it's starting to get a bit over the top. I'm
confident this isn't possible but thought I'd throw it out to the list
to see if any of you have come up with clever solutions.

Thanks,

Matt
