logout-on-session-timeout	If true, principals should be logged out when a session times out	true
password-digest	Password digest type of form: MD5-base64	MD5-base64
password-digest-algorithm	Sets the password digest algorithm	MD5
password-digest-realm	Sets the realm to use for the digest	resin
path	Path to an XML file containing the configuration
principal-cache-size	Size of the principal cache	4096
user	Inline user configuration in the form "name:password:roles"

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>

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>
