The idp.authn.LDAP.authenticator property controls the workflow for how authentication occurs against the LDAP directory:

anonSearchAuthenticator	Performs an anonymous search for the user's DN
bindSearchAuthenticator	Binds with a configured DN as a service account, then searches for the user's DN
directAuthenticator	User DNs are of a known format. i.e. CN=user_name,ou=accounts,dc=domain,dc=edu. No DN search is performed.
adAuthenticator	Configuration that leverages the AD specific @domain.com format. No DN search is performed since AD supports binding directly with that user name.

Depending on the choice above, various other properties must be set (see the reference section below).

...

If StartTLS or SSL are used, a source of trust anchors must be configured to control certificate validation, using the idp.authn.LDAP.sslConfig property:

certificateTrust	Uses the idp.authn.LDAP.trustCertificates property to load a resource containing the trust anchors (such as a file of PEM-format certificates)
keyStoreTrust	Uses the idp.authn.LDAP.trustStore property to load a keystore containing the trust anchors
jvmTrust	Uses the default JVM trust anchors (the JVM-wide "cacerts" file)

title	Properties

A number of properties are found in ldap.properties to configure LDAP authentication global defaults. Most of the time, this is sufficient to deal with most configurations without having to delve into modifying any beans, unless you're trying to chain together separately configured back-ends.

Note that the big "override everything" hook tends to be the idp.authn.LDAP.authenticator property, as most of the other properties auto-configure specific aspects of one of the built-in Authenticator beans.

Property	Type	Default	Function
idp.authn.LDAP.authenticator	Enumeration	anonSearchAuthenticator	Controls the workflow for how authentication occurs against the LDAP, one of: anonSearchAuthenticator, bindSearchAuthenticator, directAuthenticator, adAuthenticator
idp.authn.LDAP.ldapURL	LDAP URI		Connection URI for LDAP directory.
idp.authn.LDAP.useStartTLS	Boolean	true	Whether StartTLS should be used after connecting with LDAP alone.
~~idp.authn.LDAP.useSSL~~	~~Boolean~~	~~false~~	DEPRECATED. To use LDAPS, specify ldaps:// in the idp.authn.LDAP.ldapURL property.
idp.authn.LDAP.connectTimeout	Duration	PT3S	Time to wait for the TCP connection to occur.
idp.authn.LDAP.responseTimeout	Duration	PT3S	Time to wait for an LDAP response message. (Applies to every request.)
idp.authn.LDAP.connectionStrategy	Enumeration	ACTIVE_PASSIVE	Connection strategy to use when multiple URLs are supplied, one of ACTIVE_PASSIVE, ROUND_ROBIN, RANDOM
idp.authn.LDAP.sslConfig	Enumeration	certificateTrust	How to establish trust in the server's TLS certificate, one of: jvmTrust, certificateTrust, or keyStoreTrust
idp.authn.LDAP.trustCertificates	Resource path		A resource to load trust anchors from, usually a local file in %{idp.home}/credentials
idp.authn.LDAP.trustStore	Resource path		A resource to load a Java keystore containing trust anchors, usually a local file in %{idp.home}/credentials
idp.authn.LDAP.returnAttributes	Comma-sep'd Strings		List of attributes to request during authentication
idp.authn.LDAP.baseDN	String		Base DN to search against, used by anonSearchAuthenticator, bindSearchAuthenticator
idp.authn.LDAP.subtreeSearch	Boolean	false	Whether to search recursively, used by anonSearchAuthenticator, bindSearchAuthenticator
idp.authn.LDAP.userFilter	String		LDAP search filter, used by anonSearchAuthenticator, bindSearchAuthenticator
idp.authn.LDAP.bindDN	String		DN to bind with during search, used by bindSearchAuthenticator
idp.authn.LDAP.bindDNCredential	String		Password to bind with during search, used by bindSearchAuthenticator, usually set via %{idp.home}/credentials/secrets.properties
idp.authn.LDAP.dnFormat	String		A formatting string to generate the user DNs to authenticate, used by directAuthenticator, adAuthenticator
idp.authn.LDAP.resolveEntryOnFailure	Boolean	false	Whether the user's LDAP entry should be returned in the authentication response even when the user bind fails.
idp.authn.LDAP.resolveEntryWithBindDN	Boolean	false	Whether the user's LDAP entry should be resolved with the bindDN credentials rather than as the authenticated user.
idp.authn.LDAP.usePasswordPolicy	Boolean	false	Whether to use the Password Policy Control.
idp.authn.LDAP.usePasswordExpiration	Boolean	false	Whether to use the Password Expired Control.
idp.authn.LDAP.activeDirectory	Boolean	false	If you are using Active Directory, this switch will attempt to use the account states defined by AD. Note that this flag is unnecessary if you are using the 'adAuthenticator'. It is meant to be specified with one of the other authenticator types.
idp.authn.LDAP.freeIPADirectory	Boolean	false	If you are using the FreeIPA LDAP, this switch will attempt to use the account states defined by that product.
idp.authn.LDAP.eDirectory	Boolean	false	If you are using the EDirectory LDAP, this switch will attempt to use the account states defined by that product.
idp.authn.LDAP.disablePooling	Boolean	false	Whether connection pools should be used for LDAP connections used for authentication.
idp.pool.LDAP.minSize	Integer	3	Minimum LDAP connection pool size
idp.pool.LDAP.maxSize	Integer	10	Maximum LDAP connection pool size
idp.pool.LDAP.validateOnCheckout	Boolean	false	Whether to validate connections when checking them out of the pool

idp.pool.LDAP.blockWaitTime	Duration	PT3S	Duration to wait for a free connection in the pool
idp.authn.LDAP.bindPoolPassivator^4.0.1	Enumeration	none	Controls how connections in the bind pool are passivated. Connections in the bind pool may be in an authenticated state that will not allow validation searches to succeed. This property controls how bind connections are placed back into the pool. If your directory requires searches to be performed by the idp.authn.LDAP.bindDN or anonymously, this property controls that behavior. one of: none, bind, anonymousBind.

title	Beans

Properties can be used to configure all of the built-in beans used for this feature, so the only bean of relevance is below.

Bean ID	Type	Function
shibboleth.LDAPAuthenticationFactory	LDAPAuthenticationFactoryBean	Factory bean parent for defining new instances of the org.ldaptive.auth.Authenticator class if required

Advanced Features

Note that for some advanced use cases, it may be necessary to dig deeply into the Ldaptive documentation and wire up custom objects using, or based on beans in the older V3 version of authn/ldap-authn-config.xml, ultimately installing an instance of org.ldaptive.auth.Authenticator into the "authenticator" property of a particular LDAPCredentialValidator bean, which for a single validator can be done by setting the idp.authn.LDAP.authenticator property in conf/ldap.properties to that bean name. Most of the flexibility comes from all the various types of objects that can be injected into instances of the Authenticator class.

title	Attribute Retrieval

LDAP attributes are returned as part of the authentication process and exposed in the LDAPResponseContext.

Property	Sample	Result
idp.authn.LDAP.returnAttributes	uid, eduPersonAffiliation	Returns the uid and eduPersonAffiliation attributes.
	*	Returns all user attributes on the entry.
	*,+	Returns all user and operational attributes on the entry.
	1.1	No attribute returned. No search performed.

By default, attributes will be searched for using the same connection the user authenticated on. Therefore the user must have read on any attributes for those to be returned.

If you need access to attributes that user does not have read access to, then you must configure a connection pool that is authorized to read that data. The following configuration demonstrates how to add a new connection pool for that purpose.

title	Account State

The ldaptive LDAP library has the ability to extract detailed account status information from the directory during authentication. According to the Ldaptive documentation, no standard for exposing account state data has been universally adopted by LDAP vendors, but the library uses a handler which encapsulates account state information. This state contains Warning and Error types that are common to the most popular policy implementations.

Password Policy Control

The Password Policy for LDAP Directories (draft) standard is implemented by several LDAP directories, including OpenLDAP and Oracle DSEE. The Password Policy Control is used during an LDAP bind operation to request information about the user's account state.

To enable the Password Policy Control handlers in ldaptive, add the following to conf/ldap.properties:

conf/ldap.properties

Code Block

language	xml

# Use password policy control
idp.authn.LDAP.usePasswordPolicy = true

The user will be informed on the login page if there are any Password Policy warnings or errors (messages can be customized in messages/messages.properties).

Password expiration warnings have been confirmed to work with Oracle DSEE. Please notify us or edit this page if you test successfully with other directory products.

Locked Accounts

To inform the user of a locked account, some configuration is needed to detect the error code returned by the LDAP bind request.

In authn/password-authn-config.xml, add an entry to the message clasification rules defined by shibboleth.authn.Password.ClassifiedMessageMap

password-authn-config.xml

Code Block

language	xml

<entry key="AccountLocked">
    <list>
        <value>ACCOUNT_LOCKED</value>
    </list>
</entry>

This maps the error code to a AccountLocked event. It will run the empty user flow authn/conditions/account-locked and then pass control back to the form. With this configuration, the user gets the message "Your account is locked".

Debug information

Details of the AuthenticationResponse received, including the password policy controls, can be viewed using the TRACE log level in the logger of name "net.shibboleth.idp" (edit logback.xml).

Active Directory Configuration

The system comes with definitions to configure Active Directory authentication response handlers against a single directory.

Active Directory does not fully support extensible match rules (https://msdn.microsoft.com/en-us/library/cc223241.aspx).

Active Directory (by default) does not support anonymous queries (https://technet.microsoft.com/en-us/library/Cc755809%28v=WS.10%29.aspx).

Add missing Active Directory account state errors

If adAuthenticator is the authenticator set in the idp.authn.LDAP.authenticator property, Short Description values are contained in the response. If bindSearchAuthenticator is the authenticator set in the idp.authn.LDAP.authenticator property, HEX values are contained in the response. It is possible to use either or both as outlined in the following example. (http://ldapwiki.willeke.com/wiki/Common%20Active%20Directory%20Bind%20Errors)
