You still need to have the mod_dav module installed and loaded, and to actually add all users into the dav.digest.passwd file using the htdigest command:
htdigest dav.digest.htpasswd foobar.com foo
The +Indexes option also makes it to possible to browse the repository using a regular web browser (with no upload rights, of course).
<Location /webstore> DAV On Options +Indexes AuthType Digest AuthName foobar.com AuthDigestFile /home/foobar/etc/dav.digest.passwd Require valid-user ForceType text/plain Location>/webstore/foo"> Require valid-user Require user foo "/webstore/bar"> Require valid-user Require user bar
