Interface LdapConnectionHandlerCfg

All Superinterfaces:
Configuration, ConnectionHandlerCfg
public interface LdapConnectionHandlerCfg extends ConnectionHandlerCfg
A server-side interface for querying LDAP Connection Handler settings.

The LDAP Connection Handler is used to interact with clients using LDAP.

  • Method Details

    • configurationClass

      Class<? extends LdapConnectionHandlerCfg> configurationClass()
      Gets the configuration class associated with this LDAP Connection Handler.
      Specified by:
      configurationClass in interface Configuration
      Specified by:
      configurationClass in interface ConnectionHandlerCfg
      Returns:
      Returns the configuration class associated with this LDAP Connection Handler.

    • addLdapChangeListener

      void addLdapChangeListener(ConfigurationChangeListener<LdapConnectionHandlerCfg> listener)
      Register to be notified when this LDAP Connection Handler is changed.
      Parameters:
      listener - The LDAP Connection Handler configuration change listener.

    • removeLdapChangeListener

      void removeLdapChangeListener(ConfigurationChangeListener<LdapConnectionHandlerCfg> listener)
      Deregister an existing LDAP Connection Handler configuration change listener.
      Parameters:
      listener - The LDAP Connection Handler configuration change listener.

    • getAcceptBacklog

      int getAcceptBacklog()
      Gets the "accept-backlog" property.

      Specifies the maximum number of pending connection attempts that are allowed to queue up in the accept backlog before the server starts rejecting new connection attempts.

      This is primarily an issue for cases in which a large number of connections are established to the server in a very short period of time (for example, a benchmark utility that creates a large number of client threads that each have their own connection to the server) and the connection handler is unable to keep up with the rate at which the new connections are established.

      Default value: 128

      Returns:
      Returns the value of the "accept-backlog" property.

    • getAdvertisedListenAddress

      SortedSet<com.forgerock.opendj.util.Host> getAdvertisedListenAddress()
      Gets the "advertised-listen-address" property.

      The advertised address(es) which clients should use for connecting to this LDAP Connection Handler.

      Multiple addresses may be provided as separate values for this attribute. The meta-address 0.0.0.0 is not permitted.

      Default value is inherited from another property

      Returns:
      Returns an unmodifiable set containing the values of the "advertised-listen-address" property.

    • isAllowLdapV2

      boolean isAllowLdapV2()
      Gets the "allow-ldap-v2" property.

      Indicates whether connections from LDAPv2 clients are allowed.

      If LDAPv2 clients are allowed, then only a minimal degree of special support are provided for them to ensure that LDAPv3-specific protocol elements (for example, Configuration Guide 25 controls, extended response messages, intermediate response messages, referrals) are not sent to an LDAPv2 client.

      Default value: true

      Returns:
      Returns the value of the "allow-ldap-v2" property.

    • isAllowStartTls

      boolean isAllowStartTls()
      Gets the "allow-start-tls" property.

      Indicates whether clients are allowed to use StartTLS.

      If enabled, the LDAP Connection Handler allows clients to use the StartTLS extended operation to initiate secure communication over an otherwise insecure channel. Note that this is only allowed if the LDAP Connection Handler is not configured to use SSL, and if the server is configured with a valid key manager provider and a valid trust manager provider.

      Default value: false

      Returns:
      Returns the value of the "allow-start-tls" property.

    • isAllowTcpReuseAddress

      boolean isAllowTcpReuseAddress()
      Gets the "allow-tcp-reuse-address" property.

      Indicates whether the LDAP Connection Handler should reuse socket descriptors.

      If enabled, the SO_REUSEADDR socket option is used on the server listen socket to potentially allow the reuse of socket descriptors for clients in a TIME_WAIT state. This may help the server avoid temporarily running out of socket descriptors in cases in which a very large number of short-lived connections have been established from the same client system.

      Default value: true

      Returns:
      Returns the value of the "allow-tcp-reuse-address" property.

    • getBufferSize

      long getBufferSize()
      Gets the "buffer-size" property.

      Specifies the size in bytes of the LDAP response message write buffer.

      This property specifies write buffer size allocated by the server for each client connection and used to buffer LDAP response messages data when writing.

      Default value: 4096 bytes

      Returns:
      Returns the value of the "buffer-size" property.

    • getJavaClass

      String getJavaClass()
      Gets the "java-class" property.

      Specifies the fully-qualified name of the Java class that provides the LDAP Connection Handler implementation.

      Default value: org.opends.server.protocols.ldap.LDAPConnectionHandler

      Specified by:
      getJavaClass in interface ConnectionHandlerCfg
      Returns:
      Returns the value of the "java-class" property.

    • isKeepStats

      boolean isKeepStats()
      Gets the "keep-stats" property.

      Indicates whether the LDAP Connection Handler should keep statistics.

      If enabled, the LDAP Connection Handler maintains statistics about the number and types of operations requested over LDAP and the amount of data sent and received.

      Default value: true

      Returns:
      Returns the value of the "keep-stats" property.

    • getKeyManagerProvider

      String getKeyManagerProvider()
      Gets the "key-manager-provider" property.

      Specifies the name of the key manager that should be used with this LDAP Connection Handler .

      Default value is undefined

      Returns:
      Returns the value of the "key-manager-provider" property.

    • getKeyManagerProviderDn

      Dn getKeyManagerProviderDn()
      Gets the "key-manager-provider" property as a DN.

      Specifies the name of the key manager that should be used with this LDAP Connection Handler .

      Returns:
      Returns the DN value of the "key-manager-provider" property.

    • getListenAddress

      SortedSet<com.forgerock.opendj.util.Host> getListenAddress()
      Gets the "listen-address" property.

      The network interface(s) on which this LDAP Connection Handler should listen for incoming client connections.

      Multiple addresses may be provided as separate values for this attribute. If no values are provided, then the directory server will listen on all interfaces.

      Default value is inherited from another property

      Returns:
      Returns an unmodifiable set containing the values of the "listen-address" property.

    • getListenPort

      int getListenPort()
      Gets the "listen-port" property.

      Specifies the port number on which the LDAP Connection Handler will listen for connections from clients.

      Only a single port number may be provided.

      Returns:
      Returns the value of the "listen-port" property.

    • getMaxBlockedWriteTimeLimit

      long getMaxBlockedWriteTimeLimit()
      Gets the "max-blocked-write-time-limit" property.

      Specifies the maximum length of time that attempts to write data to LDAP clients should be allowed to block.

      If an attempt to write data to a client takes longer than this length of time, then the client connection is terminated.

      Default value: 2 minutes

      Returns:
      Returns the value of the "max-blocked-write-time-limit" property.

    • getMaxRequestSize

      long getMaxRequestSize()
      Gets the "max-request-size" property.

      Specifies the size in bytes of the largest LDAP request message that will be allowed by this LDAP Connection handler.

      This property is analogous to the maxBERSize configuration attribute of the Sun Java System Directory Server. This can help prevent denial-of-service attacks by clients that indicate they send extremely large requests to the server causing it to attempt to allocate large amounts of memory.

      Default value: 5 megabytes

      Returns:
      Returns the value of the "max-request-size" property.

    • getNumRequestHandlers

      Integer getNumRequestHandlers()
      Gets the "num-request-handlers" property.

      Specifies the number of request handlers that are used to read requests from clients.

      The LDAP Connection Handler uses one thread to accept new connections from clients, but uses one or more additional threads to read requests from existing client connections. This ensures that new requests are read efficiently and that the connection handler itself does not become a bottleneck when the server is under heavy load from many clients at the same time.

      Returns:
      Returns the value of the "num-request-handlers" property.

    • getProxyProtocolAllowedClient

      SortedSet<AddressMask> getProxyProtocolAllowedClient()
      Gets the "proxy-protocol-allowed-client" property.

      When the proxy protocol is enabled, this property represents the set of clients who will be allowed to establish connections to this LDAP Connection Handler and will be required to use proxy protocol.

      Valid values include a host name, a fully qualified domain name, a domain name, an IP address, or a subnetwork with subnetwork mask. Specifying a value for this property in a connection handler will override any value set in the global configuration.

      Default value is inherited from another property

      Returns:
      Returns an unmodifiable set containing the values of the "proxy-protocol-allowed-client" property.

    • isProxyProtocolEnabled

      Boolean isProxyProtocolEnabled()
      Gets the "proxy-protocol-enabled" property.

      Indicates whether the proxy protocol is enabled.

      If enabled, the LDAP Connection Handler makes the server use proxy protocol for connections with a source IP address matching an address in the proxy-protocol-allowed-client list.

      Default value is inherited from another property

      Returns:
      Returns the value of the "proxy-protocol-enabled" property.

    • getSslCertNickname

      SortedSet<String> getSslCertNickname()
      Gets the "ssl-cert-nickname" property.

      Specifies the nicknames (also called the aliases) of the keys or key pairs that the LDAP Connection Handler should use when performing SSL communication.

      The property can be used multiple times (referencing different nicknames) when server certificates with different public key algorithms are used in parallel (for example, RSA, DSA, and ECC-based algorithms). When a nickname refers to an asymmetric (public/private) key pair, the nickname for the public key certificate and associated private key entry must match exactly. A single nickname is used to retrieve both the public key and the private key. This is only applicable when the LDAP Connection Handler is configured to use SSL.

      Returns:
      Returns an unmodifiable set containing the values of the "ssl-cert-nickname" property.

    • getSslCipherSuite

      SortedSet<String> getSslCipherSuite()
      Gets the "ssl-cipher-suite" property.

      Specifies the names of the SSL cipher suites that are allowed for use in SSL or StartTLS communication.

      Returns:
      Returns an unmodifiable set containing the values of the "ssl-cipher-suite" property.

    • getSslClientAuthPolicy

      LdapConnectionHandlerCfgDefn.SslClientAuthPolicy getSslClientAuthPolicy()
      Gets the "ssl-client-auth-policy" property.

      Specifies the policy that the LDAP Connection Handler should use regarding client SSL certificates. Clients can use the SASL EXTERNAL mechanism only if the policy is set to "optional" or "required".

      This is only applicable if clients are allowed to use SSL.

      Default value: optional

      Returns:
      Returns the value of the "ssl-client-auth-policy" property.

    • getSslProtocol

      SortedSet<String> getSslProtocol()
      Gets the "ssl-protocol" property.

      Specifies the names of the SSL protocols that are allowed for use in SSL or StartTLS communication.

      Returns:
      Returns an unmodifiable set containing the values of the "ssl-protocol" property.

    • getTrustManagerProvider

      SortedSet<String> getTrustManagerProvider()
      Gets the "trust-manager-provider" property.

      Specifies the name(s) of the trust manager(s) that should be used with the LDAP Connection Handler .

      Default value is undefined

      Returns:
      Returns an unmodifiable set containing the values of the "trust-manager-provider" property.

    • getTrustManagerProviderDns

      SortedSet<Dn> getTrustManagerProviderDns()
      Gets the "trust-manager-provider" property as a set of DNs.

      Specifies the name(s) of the trust manager(s) that should be used with the LDAP Connection Handler .

      Returns:
      Returns the DN values of the "trust-manager-provider" property.

    • isUseSsl

      boolean isUseSsl()
      Gets the "use-ssl" property.

      Indicates whether the LDAP Connection Handler should use SSL.

      If enabled, the LDAP Connection Handler will use SSL to encrypt communication with the clients.

      Default value: false

      Returns:
      Returns the value of the "use-ssl" property.

    • isUseTcpKeepAlive

      boolean isUseTcpKeepAlive()
      Gets the "use-tcp-keep-alive" property.

      Indicates whether the LDAP Connection Handler should use TCP keep-alive.

      If enabled, the SO_KEEPALIVE socket option is used to indicate that TCP keepalive messages should periodically be sent to the client to verify that the associated connection is still valid. This may also help prevent cases in which intermediate network hardware could silently drop an otherwise idle client connection, provided that the keepalive interval configured in the underlying operating system is smaller than the timeout enforced by the network hardware.

      Default value: true

      Returns:
      Returns the value of the "use-tcp-keep-alive" property.

    • isUseTcpNoDelay

      boolean isUseTcpNoDelay()
      Gets the "use-tcp-no-delay" property.

      Indicates whether the LDAP Connection Handler should use TCP no-delay.

      If enabled, the TCP_NODELAY socket option is used to ensure that response messages to the client are sent immediately rather than potentially waiting to determine whether additional response messages can be sent in the same packet. In most cases, using the TCP_NODELAY socket option provides better performance and lower response times, but disabling it may help for some cases in which the server sends a large number of entries to a client in response to a search request.

      Default value: true

      Returns:
      Returns the value of the "use-tcp-no-delay" property.
