Class LdapLoginModule

java.lang.Object
  org.eclipse.jetty.plus.jaas.spi.AbstractLoginModule
      org.eclipse.jetty.plus.jaas.spi.LdapLoginModule

All Implemented Interfaces:

LoginModule

public class LdapLoginModule
extends AbstractLoginModule

A LdapLoginModule for use with JAAS setups

The jvm should be started with the following parameter:

-Djava.security.auth.login.config=etc/ldap-loginModule.conf

and an example of the ldap-loginModule.conf would be:

 ldaploginmodule {
    org.eclipse.jetty.server.server.plus.jaas.spi.LdapLoginModule required
    debug="true"
    contextFactory="com.sun.jndi.ldap.LdapCtxFactory"
    hostname="ldap.example.com"
    port="389"
    bindDn="cn=Directory Manager"
    bindPassword="directory"
    authenticationMethod="simple"
    forceBindingLogin="false"
    userBaseDn="ou=people,dc=alcatel"
    userRdnAttribute="uid"
    userIdAttribute="uid"
    userPasswordAttribute="userPassword"
    userObjectClass="inetOrgPerson"
    roleBaseDn="ou=groups,dc=example,dc=com"
    roleNameAttribute="cn"
    roleMemberAttribute="uniqueMember"
    roleObjectClass="groupOfUniqueNames";
    };

Method Summary

boolean	abort()
boolean	bindingLogin(String username, Object password) binding authentication check This methode of authentication works only if the user branch of the DIT (ldap tree) has an ACI (acces control instruction) that allow the access to any user or at least for the user that logs in.
boolean	commit()
static String	convertCredentialJettyToLdap(String encryptedPassword)
static String	convertCredentialLdapToJetty(String encryptedPassword)
protected boolean	credentialLogin(Object webCredential) password supplied authentication check
protected String	doRFC2254Encoding(String inputString)
Hashtable<Object,Object>	getEnvironment() get the context for connection
UserInfo	getUserInfo(String username) get the available information about the user for this LoginModule, the credential can be null which will result in a binding ldap authentication scenario roles are also an optional concept if required
void	initialize(Subject subject, CallbackHandler callbackHandler, Map sharedState, Map options) Init LoginModule.
boolean	login() since ldap uses a context bind for valid authentication checking, we override login() if credentials are not available from the users context or if we are forcing the binding check then we try a binding authentication check, otherwise if we have the users encoded password then we can try authentication via that mechanic

Method Detail

getUserInfo

public UserInfo getUserInfo(String username)
                     throws Exception

get the available information about the user

for this LoginModule, the credential can be null which will result in a binding ldap authentication scenario

roles are also an optional concept if required

Specified by:

getUserInfo in class AbstractLoginModule

Parameters:

username -

Returns:

Throws:

Exception

doRFC2254Encoding

protected String doRFC2254Encoding(String inputString)

login

public boolean login()
              throws LoginException

since ldap uses a context bind for valid authentication checking, we override login()

if credentials are not available from the users context or if we are forcing the binding check then we try a binding authentication check, otherwise if we have the users encoded password then we can try authentication via that mechanic
