// ADConnection - A Java class that encapsulates a JNDI connection to
// an Active Directory
//
// Written by Jeremy E. Mortis mortis@ucalgary.ca 2002-07-03
//
// Note that password changes require an SSL connection to the Active Directory,
// but other types of calls do not.
//
// To set up the SSL connection, check out:
// http://java.sun.com/j2se/1.3/docs/tooldocs/win32/keytool.html
// http://www.microsoft.com/windows2000/techinfo/planning/security/casetupsteps.asp
