/**
* Represents a connection to an LDAP server. <P>
*
* Use objects of this class to perform LDAP operations (such as
* search, modify, and add) on an LDAP server. <P>
*
* To perform an LDAP operation on a server, you need to follow
* these steps: <P>
*
* <OL>
* <LI>Create a new <CODE>LDAPConnection</CODE> object.
* <LI>Use the <CODE>connect</CODE> method to connect to the
* LDAP server.
* <LI>Use the <CODE>authenticate</CODE> method to authenticate
* to server.
* <LI>Perform the LDAP operation.
* <LI>Use the <CODE>disconnect</CODE> method to disconnect from
* the server when done.
* </OL>
* <P>
*
* All operations block until completion (with the exception of
* the search method in which the results may not all return at
* the same time).
* <P>
*
* This class also specifies a default set of constraints
* (such as the maximum length of time to allow for an operation before timing out)
* which apply to all operations. To get and set these constraints,
* use the <CODE>getOption</CODE> and <CODE>setOption</CODE> methods.
* To override these constraints for an individual operation,
* define a new set of constraints by creating a <CODE>LDAPConstraints</CODE>
* object and pass the object to the method for the operation. For search
* operations, additional constraints are defined in <CODE>LDAPSearchConstraints</CODE>
* (a subclass of <CODE>LDAPConstraints</CODE>). To override the default search
* constraints, create an <CODE>LDAPSearchConstraints</CODE> object and pass it
* to the <CODE>search</CODE> method.
* <P>
*
* If you set up your client to follow referrals automatically,
* an operation that results in a referral will create a new connection
* to the LDAP server identified in the referral. In order to have
* your client authenticate to that LDAP server automatically, you need
* to define a class that implements the <CODE>LDAPRebind</CODE> interface.
* In your definition of the class, you need to define a
* <CODE>getRebindAuthentication</CODE> method that creates an <CODE>LDAPRebindAuth</CODE>
* object containing the distinguished name and password to use for reauthentication.
* <P>
*
* Most errors that occur raise the same exception (<CODE>LDAPException</CODE>).
* In order to determine the exact problem that occurred, you can retrieve the
* result code from this exception and compare its value against a set of defined
* result codes.
* <P>
*
* @version 1.0
* @see netscape.ldap.LDAPConstraints
* @see netscape.ldap.LDAPSearchConstraints
* @see netscape.ldap.LDAPRebind
