/**
* 
* Implementation of Realm that works with a directory server accessed via the Java Naming and
* Directory Interface (JNDI) APIs. The following constraints are imposed on the data structure in the underlying
* directory server:
* 
* <ul>
* <li>Each user that can be authenticated is represented by an individual element in the top level
* <code>DirContext</code> that is accessed via the <code>connectionURL</code> property.</li>
* <li>If a socket connection cannot be made to the <code>connectURL</code> an attempt will be made to use the
* <code>alternateURL</code> if it exists.</li>
* <li>Each user element has a distinguished name that can be formed by substituting the presented username into a
* pattern configured by the <code>userPattern</code> property.</li>
* <li>Alternatively, if the <code>userPattern</code> property is not specified, a unique element can be located by
* searching the directory context. In this case:
* <ul>
* <li>The <code>userSearch</code> pattern specifies the search filter after substitution of the username.</li>
* <li>The <code>userBase</code> property can be set to the element that is the base of the subtree containing users. If
* not specified, the search base is the top-level context.</li>
* <li>The <code>userSubtree</code> property can be set to <code>true</code> if you wish to search the entire subtree of
* the directory context. The default value of <code>false</code> requests a search of only the current level.</li>
* </ul>
* </li>
* <li>The user may be authenticated by binding to the directory with the username and password presented. This method
* is used when the <code>userPassword</code> property is not specified.</li>
* <li>The user may be authenticated by retrieving the value of an attribute from the directory and comparing it
* explicitly with the value presented by the user. This method is used when the <code>userPassword</code> property is
* specified, in which case:
* <ul>
* <li>The element for this user must contain an attribute named by the <code>userPassword</code> property.
* <li>The value of the user password attribute is either a cleartext String, or the result of passing a cleartext
* String through the <code>RealmBase.digest()</code> method (using the standard digest support included in
* <code>RealmBase</code>).
* <li>The user is considered to be authenticated if the presented credentials (after being passed through
* <code>RealmBase.digest()</code>) are equal to the retrieved value for the user password attribute.</li>
* </ul>
* </li>
* <li>Each group of users that has been assigned a particular role may be represented by an individual element in the
* top level <code>DirContext</code> that is accessed via the <code>connectionURL</code> property. This element has the
* following characteristics:
* <ul>
* <li>The set of all possible groups of interest can be selected by a search pattern configured by the
* <code>roleSearch</code> property.</li>
* <li>The <code>roleSearch</code> pattern optionally includes pattern replacements "{0}" for the distinguished name,
* and/or "{1}" for the username, and/or "{2}" the value of an attribute from the user's directory entry (the attribute
* is specified by the <code>userRoleAttribute</code> property), of the authenticated user for which roles will be
* retrieved.</li>
* <li>The <code>roleBase</code> property can be set to the element that is the base of the search for matching roles.
* If not specified, the entire context will be searched.</li>
* <li>The <code>roleSubtree</code> property can be set to <code>true</code> if you wish to search the entire subtree of
* the directory context. The default value of <code>false</code> requests a search of only the current level.</li>
* <li>The element includes an attribute (whose name is configured by the <code>roleName</code> property) containing the
* name of the role represented by this element.</li>
* </ul>
* </li>
* <li>In addition, roles may be represented by the values of an attribute in the user's element whose name is
* configured by the <code>userRoleName</code> property.</li>
* <li>A default role can be assigned to each user that was successfully authenticated by setting the
* <code>commonRole</code> property to the name of this role. The role doesn't have to exist in the directory.</li>
* <li>If the directory server contains nested roles, you can search for them by setting <code>roleNested</code> to
* <code>true</code>. The default value is <code>false</code>, so role searches will not find nested roles.</li>
* <li>Note that the standard <code><security-role-ref></code> element in the web application deployment
* descriptor allows applications to refer to roles programmatically by names other than those used in the directory
* server itself.</li>
* </ul>
* 
* WARNING - There is a reported bug against the Netscape provider code
* (com.netscape.jndi.ldap.LdapContextFactory) with respect to successfully authenticated a non-existing user. The
* report is here: https://bz.apache.org/bugzilla/show_bug.cgi?id=11210 . With luck, Netscape has updated their provider
* code and this is not an issue.
