PaperCut NG is a modern application designed with a modern architecture. It supports plug-ins and extensions at a number of different levels. One such layer is the User Directory source. Organizations with very complex domains, such as those seen in large universities, can be accommodated either with the standard options, or if the standard options are not sufficient, via a custom plug-in.

For example, a University may have multiple domains, one running Active Directory and the other LDAP/NIS. A custom plug-in could support this by first querying Domain A, and if the user is not found, the query Domain B via LDAP. The PaperCut NG development team is happy to provide API documentation and sample source code to assist organizations with custom requirements.
