The <authenticator> directive configures Resin's built-in authentication for the Servlet login, i.e. to support getUserPrincipal and isUserInRole.

directives

XmlAuthenticator

This article requires cleanup and may refer to a legacy version of Resin. Please visit http://www.caucho.com/documentation/ for the most up-to-date documentation.

The XmlAuthenticator is a simple authentication scheme where an XML file or a configuration file specifies the users directly. XmlAuthenticator is useful when you have a small number of known users.

<init> directives

Example

resin-web.xml

<web-app xmlns="http://caucho.com/ns/resin">
  <authenticator>
    <type>com.caucho.server.security.XmlAuthenticator</type>
    <init>
      <password-digest>none</password-digest>
      <user>Harry Potter:quidditch:user</user>
    </init>
  </authenticator>
  ...
</web-app>

JdbcAuthenticator

This article requires cleanup and may refer to a legacy version of Resin. Please visit http://www.caucho.com/documentation/ for the most up-to-date documentation.

The JdbcAuthenticator uses a database to store user authentication.

<init> directives

Example

resin-web.xml

<web-app xmlns="http://caucho.com/ns/resin">
  <database jndi-name="java:comp/env/jdbc/test">
    <driver type="org.postgresql.Driver">
      <url>jdbc:postgresql://localhost/test</url>
      <user>harry</user>
    </driver>
  </database>

  <authenticator>
    <type>com.caucho.server.security.JdbcAuthenticator</type>
    <init>
      <data-source>java:comp/env/jdbc/test</data-source>
    </init>
  </authenticator>
  ...
</web-app>

Here is how this needs to be configured for FORM authentication:

     <authenticator type='com.caucho.server.security.JdbcAuthenticator'>
       <init>
         <data-source>jdbc/MyDataSource</data-source>
         ...
         <password-digest>
            <realm>resin</realm>
            <algorithm>md5</algorithm>
            <format>base64</format>
         </password-digest>
       </init>
     </authenticator>

JaasAuthenticator - using a JAAS LoginModule

Main article: JaasAuthenticator

resin-web.xml

<web-app xmlns="http://caucho.com/ns/resin">

 <authenticator type="com.caucho.server.security.JaasAuthenticator">
     <init>
         <login-module>com.sun.security.auth.module.Krb5LoginModule</login-module>
         <init-param>
              <debug>true</debug>
        </init-param>
     </init>
 </authenticator>

</web-app>

LDAP authentication

The Sun JDK includes a JndiLoginModule, which in turn is used with Resin's JaasAuthenticator to authenticate against an LDAP server.

Example

resin-web.xml

<web-app xmlns="http://caucho.com/ns/resin">
  <authenticator type="com.caucho.server.security.JaasAuthenticator">
   <init>
     <login-module>com.sun.security.auth.module.JndiLoginModule</login-module>

     <init-param user.provider.url="ldap://ldap.hogwarts.com/ou=People"/>
     <init-param group.provider.url="ldap://ldap.hogwarts.com/ou=Groups"/>

     <init-param debug="true"/>
   </init>
  </authenticator>
</web-app>
