How to allow read access to all users and writes to some specific with apache/webdav?

polik · 03-11-2009, 12:06 PM

Hi everybody,

I have a server containing information that should be readable by all users, while only admin users should be allowed to write.
One of my attempts was to use two <Directory> directives referring to the same path, the first to grant read only access, the second to grant write access to authenticated and specific users only.
The first part sounds easy, when you talk about it, but I did not find a solution yet.

Any ideas?
Thanks.

look at this may this...

[folder]

comment = share folder
path = /home/folder
browseable = yes
valid users = user1,user2,user3,user4
invalid user =
read list = user1,user2
write list = user3,user4
writable = yes
create mask = 0744
guest ok = no

You can use limit, here is a snippet:

Quote:

<ifmodule mod_dav.c>
<directory /path/to/webdav/>
allow from 127.0.0.1 ::1
allow from 192.0.2.1
# other allowed clients
Dav on
AuthType Basic
AuthName "MySystemName WebDAV Storage"
AuthUserFile /path/to/web/etc/passwd.dav
Require valid-user
# These are the HTTP methods used in DAV, beyond the usual GET/HEAD/OPTIONS
# <limit put post delete propfind proppatch mkcol copy move lock unlock>
# Require user administrator
# </limit>
</directory>

or something like,

Quote:

<directory /path/to/webdav/sensitive/>
<limitexcept get options propfind>
Require user administrator
</limitexcept>
</directory>

just explore more oh how you want to limit some other users.

Let's make is simpler and try to grant read access only to everyone, without authentication.
My current configuration is the following:

Alias /deliveries "/export/deliveries"

<Directory /export/deliveries>
Dav On

Order Allow,Deny
Allow from all

AuthType Basic
Options Indexes FollowSymLinks
IndexOptions FancyIndexing NameWidth=*
</Directory>

How does it work? Everyone can read and write, but none can delete.
It is not what I need, yet.

The client is a windows XP sp3, mapping the network place as http://my_server:80/deliveries

Sorry, I have to correct myself: the above configuration allows or not deleting depending on the object you are managing. In particular it is not possible to delete or rename directories, while it is possible to delete files.

In that case, the second snippet I gave you satisfies what you need.

Quote:

<directory /export/deliveries>
Dav On

Order Allow,Deny
Allow from all

AuthType Basic
Options Indexes FollowSymLinks
IndexOptions FancyIndexing NameWidth=*
<limitexcept get options propfind>
Require user administrator
</limitexcept>
</directory>

This means that everyone else is allowed readonly except administrator, who can write to the directory
