/**
* This class is the starting context for performing
* LDAPv3-style extended operations and controls.
*<p>
* See <tt>javax.naming.InitialContext</tt> and
* <tt>javax.naming.InitialDirContext</tt> for details on synchronization,
* and the policy for how an initial context is created.
*
* <h4>Request Controls</h4>
* When you create an initial context (<tt>InitialLdapContext</tt>),
* you can specify a list of request controls.
* These controls will be used as the request controls for any
* implicit LDAP "bind" operation performed by the context or contexts
* derived from the context. These are called <em>connection request controls</em>.
* Use <tt>getConnectControls()</tt> to get a context's connection request
* controls.
*<p>
* The request controls supplied to the initial context constructor
* are <em>not</em> used as the context request controls
* for subsequent context operations such as searches and lookups.
* Context request controls are set and updated by using
* <tt>setRequestControls()</tt>.
*<p>
* As shown, there can be two different sets of request controls
* associated with a context: connection request controls and context
* request controls.
* This is required for those applications needing to send critical
* controls that might not be applicable to both the context operation and
* any implicit LDAP "bind" operation.
* A typical user program would do the following:
*<blockquote><pre>
* InitialLdapContext lctx = new InitialLdapContext(env, critConnCtls);
* lctx.setRequestControls(critModCtls);
* lctx.modifyAttributes(name, mods);
* Controls[] respCtls = lctx.getResponseControls();
*</pre></blockquote>
* It specifies first the critical controls for creating the initial context
* (<tt>critConnCtls</tt>), and then sets the context's request controls
* (<tt>critModCtls</tt>) for the context operation. If for some reason
* <tt>lctx</tt> needs to reconnect to the server, it will use
* <tt>critConnCtls</tt>. See the <tt>LdapContext</tt> interface for
* more discussion about request controls.
*<p>
* Service provider implementors should read the "Service Provider" section
* in the <tt>LdapContext</tt> class description for implementation details.
