Dav+ldap

[rifqi]

hi all..,
i've installed mod_dav+mod_auth_ldap on my obsd 4.4, this is my apache config
Alias /dav "/var/www/dav/"

<Directory "/var/www/dav">
DAV On
AuthName "LDAP Authentication"
AuthType Basic
AuthLDAPURL ldap://10.13.254.xx/ou=people,o=xx,dc=ac,dc=id?uid
Require valid-user
Options Indexes MultiViews
AllowOverride None
Order allow,deny
Allow from all
</Directory>
my ldap auth work fine, but i can't access my dav directory with webdav://server_name/dav/ with no error on my apache log
dav directory on /var/www is exist, and owned by www user

this is error report on konqueror

An error occurred while loading webdav://10.55.1.xx/dav/:
The file or folder webdav://10.55.1.xx/dav/ does not exist.

Thanks a lot
