LDAP Authentication Project + More Work Possible

Greetings. We have 3 servers one of which is an email server which we would like to authenticate the other two via LDAP. The server already has ldap protocol and authenticates users for our email client but we are having trouble authenticating from the other servers. We would also like to create the users for the ldap from our core site using a joomla membership plugin. We also have a private file system plugin for users to allow them to manage files in a personal folder on the core joomla site, we would like as a second task to set some folder size limits based on user group. We have multiple other tasks ready to be implemented as soon as we can find a suitable freelancer with these two initial tasks.
