Access Windows users network home folders from web
I am looking for open source program(s) that will allow about 500 staff members access to there network home folders from home.
The network environment is a standard Active Directory Windows 2003 login system, and all the staff members documents are stored on standard Windows Shares. I would like a product(s) that will integrate with Active Directory allowing for users to enter there username and password, then be mapped to there network home folder. I have read articles on Apache, WebDAV and mod_authz_ldap, that seems to be close, but I cant seem to find HOWTO to do close to what I would like to do. I have also read Zope has something pretty close, but seems to be more for web authoring not home folder access.
If anyone has any suggestions or links to something that may work, let me know!
