Redmine

Hi,
I have setup a redmine server and used LDAP and internal authentication to access remine. I have enabled redmine_webdav plugin in redmine but having problem logging in using LDAP authentication. I get a apache login window when i access http://myredmineserver/ from web browser. I can access both redmine and webdav share from client using my internal redmine authentication but not the LDAP. My webdav configuration is:

PerlLoadModule Apache::Authn::RedmineAdvanced
<Location />
AuthType Basic
AuthName REDMINE
Require valid-user
PerlAccessHandler Apache::Authn::RedmineAdvanced::access_handler
PerlAuthenHandler Apache::Authn::RedmineAdvanced::authen_handler
RedmineDSN "DBI:mysql:database=redmine;host=192.168.10.1;port=3306"
RedmineDbUser "redmine"
RedmineDbPass "password"
RedmineAuthenticationOnly "On"
Order allow,deny
Allow from 127.0.0.1
Satisfy Any
</Location>

I have also tried by adding

PerlLoadModule Authen::Simple::LDAP

Have anyone faced this problem? Any help would be great.
