suPHP, proftpd, permissions problem

[TheRudy]

Hey guys,

Need a little help as I'm stuck.

I have a custom setup on the server and proftpd running (only when required).

The folder structure for websites is like this:

/home/www/domain.tld/public_html

www = owner: www_users, group: www_users
domain.tld = owner: www_users, group: www_users
public_html = owner: www_users, group: www_users

All sites have the same owner and are in the same group as above.

Now I had to install suPHP which works fine.

For each site, I created a new user for proftpd and added the user to group www_users. So that the required sites (just a few of them) have their own username/password for ftp login.

Of course the problem here are the permissions.

If I leave it as it is, suPHP is working fine, proftpd can login, view files but cannot upload (550 permission denied error).

If I change (chown -R ftpuser1:www_users *) for a domain (public_html folder) the owner to "ftpuser1", group as "www_users", FTP is working fine, I can upload, delete,...

But the website gives the 500 error:

[Thu Jan 19 10:12:47 2012] [warn] Directory /home/www/domain.tld is not owned by ftpuser1

Even if I chown "domain.tld" folder, suphp still gives me the above warn.

I can't figure out how to convince suphp to allow ftpuser1 as the owner.

/etc/suphp/suphp.conf

Current folder structure (suphp works, proftpd gives 550 error):

drwxr-xr-x  3 www_users www_users 4096 Aug 13  2009 domain.tld

Inside "domain.tld":

drwxr-xr-x 21 www_users www_users 4096 Jan 19 10:12 public_html

Inside the "public_html" all files and folders are "www_users" owner and group.

id ftpuser1:

uid=5003(ftpuser1) gid=5001(www_users) groups=5001(www_users)

Need help please.

Setting root:root to /home/www solved the problem!
