>Is there a way to query the NDS for user information like their log in ID, their name, and other information like phone number?

You can install ADSI; ADSI supports queries against NDS. Novell also has both API and ActiveX libraries that are Novell-specific; they usually require you to use the Novell client. And there are third-party tools like NetLib that support NetWare environments as well; NetLib is available from the authors or through Hallogram - there is a link to it in the Classified section of UT.
