I have been looking through the code, trying to sort out where i could step in and use an LDAP server for authentication. There is currently an LDAP server to control remote access to a large portion of the server rack i am hosted on, i would like to be able to integrate this into my airtime server. Me and the admin of the server station are working on reading through your PHP to see how we can fit this in for us. But it seems like it could be an easy option to install on the admin page.
