Hello Newbies, I was wondering if there is any commercial software for Linux which support auhthentication, file sharing, LDAP, mail, web etc. I know that we can get most of the above services using different free software. I have in fact done that. But when it comes to client authentication, I am having problems with Samba since all the clients in our office are Win2K. Any help or direction is highly appreciated. Thanks in advamce. Vinay.
