vfs_dav: WebDAV support for phpGroupWare
|
||
|
|
----------------------------------------
|
||
|
|
|
||
|
|
WARNING::This is still alpha-quality code, and may delete all your files,
|
||
|
|
corrupt all your data, and run away with your daughter. Dont use it unless
|
||
|
|
you know what your doing.
|
||
|
|
|
||
|
|
|
||
|
|
This package contains classes and patches implementing a virtual filesystem
|
||
|
|
for phpGroupWare (0.9.14) that uses a WebDAV file repository as a
|
||
|
|
storage area. This allows you to store your files online in phpgroupware,
|
||
|
|
in a way that cooperates well with other web applications (for instance,
|
||
|
|
in Windows you can then access your files as a "web folder", and similarly
|
||
|
|
KDE, Gnome, MacOSX, and a multitude of applications all include some way of
|
||
|
|
browsing files on a WebDAV share)
|
||
|
|
|
||
|
|
Features
|
||
|
|
--------
|
||
|
|
- (should be) fully compatible with the WebDAV standard, as specified in
|
||
|
|
RFC2518 http://www.ietf.org/rfc/rfc2518.txt (NB : this doesn't imply that it
|
||
|
|
is :) only that I consider it a bug if it isn't )
|
||
|
|
- Maps vfs properties (eg creator_id etc) to the Dublin Core metadata
|
||
|
|
specification (http://dublincore.org/) (eg "author") where possible, and
|
||
|
|
stores them as DAV properties
|
||
|
|
- Limited Access control support - when you create a dir in groupware, it
|
||
|
|
puts a .htaccess file in it with "limit user <username>" in it. Combined
|
||
|
|
with an Apache module authenticating against your phpgroupware account
|
||
|
|
database, this provides reasonable user-security (proper ACL support is
|
||
|
|
trickier to implement though :(
|
||
|
|
|
||
|
|
TODO:
|
||
|
|
-----
|
||
|
|
- DELTA-V versioning extensions, using the subversion DELTA-V server
|
||
|
|
- Journalling -> Versioning. Journalling is currently unimplemented
|
||
|
|
- Locking (phpGroupWare doesn't really have any locking mechanism yet)
|
||
|
|
- ACL support for users accessing through an external webdav client.
|
||
|
|
|
||

|
Installation
|
||
|
|
------------
|
||
|
|
To install:
|
||
|
|
|
||
|
|
1/ Setup a WebDAV server - currently this code has only been well tested using
|
||
|
|
Apache's mod_dav (http://www.webdav.org/mod_dav/). To setup mod_dav ensure
|
||
|
|
that you have the module installed correctly ( RTFM :) and create a virtual
|
||
|
|
host (eg files.yourdomain.com) something like this:
|
||
|
|
|
||
|
|
<VirtualHost files.yourdomain.com:80>
|
||
|
|
AccessFileName .htaccess
|
||
|
|
ServerAdmin webmaster@yourdomain.com
|
||
|
|
DocumentRoot /var/files
|
||
|
|
<Location />
|
||
|
|
AllowOverride All
|
||
|
|
Options +Indexes
|
||
|
|
DAV on
|
||
|
|
DirectoryIndex /
|
||
|
|
RemoveHandler .php .php4 .php3 .phtml
|
||
|
|
</Location>
|
||
|
|
<Files ~ "^\.ht">
|
||
|
|
#This ensures phpgroupware can modify .htaccess files
|
||
|
|
order deny,allow
|
||
|
|
deny from all
|
||
|
|
#make sure your phpgroupware server is included here.
|
||
|
|
allow from localhost .localdomain 192.168.
|
||
|
|
</Files>
|
||
|
|
ServerName files.yourdomain.com
|
||
|
|
ErrorLog logs/dav_err
|
||
|
|
CustomLog logs/dav_acc combined
|
||
|
|
</VirtualHost>
|
||
|
|
|
||
|
|
2/ On the setup page (phpgroupware/setup/config.php) specify
|
||
|
|
the WebDAV server URL (eg http://files.yourdomain.com ) in the: "Full path
|
||
|
|
for users and groups files" text area, and select DAV in:
|
||
|
|
"Select where you want to store/retrieve filesystem information"
|
||
|
|
combo. If your file repository supports SSL you might want to enter
|
||
|
|
'https://files.yourdomain.com' instead - note that phpGroupWare itself wont
|
||
|
|
use SSL to access the repository, but when it redirects the users browser to
|
||
|
|
the repository it will use the secure https url.
|
||
|
|
|
||
|
|
3/ Make sure your WebDAV repository contains a "home" directory (important!)
|
||
|
|
So if your WebDAV directory is /var/files, you would need:
|
||
|
|
/var/files/
|
||
|
|
/var/files/home/
|
||
|
|
|
||
|
|
4/ To enable authentication you must use a third-party Apache authentication
|
||
|
|
module. Which you use depends on how you have setup authentication in
|
||
|
|
phpGroupWare - for instance if you use an SQL DB (the default) then set up
|
||
|
|
mod_auth_pgsql (http://www.giuseppetanzilli.it/mod_auth_pgsql/) or
|
||
|
|
mod_auth_mysql (http://modauthmysql.sourceforge.net/)
|
||
|
|
An example .htaccess file is included for postgresql - mysql would be
|
||
|
|
similar. Your file repository also needs to be configured to allow
|
||
|
|
phpGroupWare to write .htaccess files (the setup in (3) will allow this)
|
||
|
|
|
||
|
|
Note that using an Apache module for authentication is not strictly
|
||
|
|
required in order to use WebDAV within phpGroupWare.
