| <FONT color="green">035</FONT> * {@link LdapContextFactory} implementation using the default Sun/Oracle JNDI Ldap API, utilizing JNDI<a name="line.35"></a> |
| <FONT color="green">036</FONT> * environment properties and an {@link javax.naming.InitialContext}.<a name="line.36"></a> |
| <FONT color="green">037</FONT> * <h2>Configuration</h2><a name="line.37"></a> |
| <FONT color="green">038</FONT> * This class basically wraps a default template JNDI environment properties Map. This properties map is the base<a name="line.38"></a> |
| <FONT color="green">039</FONT> * configuration template used to acquire JNDI {@link LdapContext} connections at runtime. The<a name="line.39"></a> |
| <FONT color="green">040</FONT> * {@link #getLdapContext(Object, Object)} method implementation merges this default template with other properties<a name="line.40"></a> |
| <FONT color="green">041</FONT> * accessible at runtime only (for example per-method principals and credentials). The constructed runtime map is the<a name="line.41"></a> |
| <FONT color="green">042</FONT> * one used to acquire the {@link LdapContext}.<a name="line.42"></a> |
| <FONT color="green">043</FONT> * <p/><a name="line.43"></a> |
| <FONT color="green">044</FONT> * The template can be configured directly via the {@link #getEnvironment()}/{@link #setEnvironment(java.util.Map)}<a name="line.44"></a> |
| <FONT color="green">045</FONT> * properties directly if necessary, but it is usually more convenient to use the supporting wrapper get/set methods<a name="line.45"></a> |
| <FONT color="green">046</FONT> * for various environment properties. These wrapper methods interact with the environment<a name="line.46"></a> |
| <FONT color="green">047</FONT> * template on your behalf, leaving your configuration cleaner and easier to understand.<a name="line.47"></a> |
| <FONT color="green">048</FONT> * <p/><a name="line.48"></a> |
| <FONT color="green">049</FONT> * For example, consider the following two identical configurations:<a name="line.49"></a> |

| <FONT color="green">062</FONT> * </pre><a name="line.62"></a> |
| <FONT color="green">063</FONT> * As you can see, the 2nd configuration block is a little more difficult to read and also requires knowledge<a name="line.63"></a> |
| <FONT color="green">064</FONT> * of the underlying JNDI Context property keys. The first is easier to read and understand.<a name="line.64"></a> |
| <FONT color="green">065</FONT> * <p/><a name="line.65"></a> |
