Samba-Apache-Webdav permission problem with user www-data

I'm not sure if this should be in the newbie section, but I am somewhat of a newbie, so here goes:

In a home network, I have an Xubuntu file server with a Samba share that has me as the owner and authorizes me to access the share.

On another computer, I have Mint running and providing various services, including webdav on Apache with SSL. In the var/www/webdav directory of the Mint computer, I have the Xubuntu Samba share mounted. This is supposed to allow me to access the Samba share from the public internet.

Everything works fine except for one big problem: Apache requires the owner of the webdav directory to be user "www-data," and I can't figure out how to give www-data access to the Samba share, since www-data is not a user on the Xubuntu computer, and moreover I don't know the password for user www-data.

Can anyone figure out how to get around this problem? In particular, is there a way to configure the Samba share on the Xubuntu computer so that user www-data on the Mint computer can have access to it?

(Incidentally, I have my reasons for using two computers, one as a file server and one as a web server. Also, I am thinking about switching to NFS instead of Samba, but I'm not sure if even that would solve my problem.)

Apache requires the owner of the webdav directory to be user "www-data
It isn't Apache that requires this. Debian/Ubuntu and their derivatives such as Mint/Xubuntu use www-data as the owner:group for apache web server directories. Most Linux systems use apache:apache. This is a system user:group and there is not password. If you want a specific user to have access you would put that user in the www-data group. If you want the users in the www-data group to have access to the Samba share, you would need to put them in whatever group the Samba mount is in with permissions you desire.

Thanks, Yancek. I forgot to respond earlier, but your post was helpful in getting my problem solved. It helped me formulate my thoughts regarding the permissions. in particular, adding www-data to the group of the user authorized to access the samba share was what needed to be done. I think that might be just a tad bit of a security risk, in case someone on the public internet hijacks the www-data account somehow, but I've used a very strong password, so that seems unlikely.
