ActiveDirectory Module

Properties   Methods   Events   Config Settings   Errors  

The ActiveDirectory module can be used to authenticate users against Active Directory using Kerberos 5.0.

Syntax

IPWorksAuth.ActiveDirectory

Remarks

The ActiveDirectory class authenticates users against Active Directory. Authentication is performed using the Kerberos protocol defined in RFC 1510 and RFC 4120.

Authentication

When Authenticate is called the class will attempt to authenticate the user with the Active Directory server. The class will communicate with the ADHost to obtain a service ticket and populate AuthToken. The following properties are required when calling this method:

A typical sequence of messages would be:

  • KRB_AS_REQ -> KDC
  • KRB_AS_REP <- KDC
  • KRB_TGS_REQ -> KDC
  • KRB_TGS_REP <- KDC
  • AuthToken is populated with the constructed KRB_AP_REP message.

Communication with the ADHost can be seen through the PITrail event.

If Timeout is set to a positive value, the class will wait for the operation to complete before returning control.

The class will use DoEvents to enter an efficient wait loop during any potential waiting period, making sure that all system events are processed immediately as they arrive. This ensures that the host application does not freeze and remains responsive.

If Timeout expires, and the operation is not yet complete, the class .

Note: By default, all timeouts are inactivity timeouts, that is, the timeout period is extended by Timeout seconds when any amount of data is successfully sent or received.

The default value for the Timeout property is 60 seconds.

- (void)onUserList:(NSString*)name :(NSString*)description :(NSString*)lastLogon :(NSString*)memberOf :(NSString*)dn;

Remarks

This event is fired once for each user entry returned when the ListGroupMembers method is called.

Config Settings (ActiveDirectory Module)

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the Config method.

ActiveDirectory Config Settings

CredentialsCacheFile:   The credentials cache file.

This setting specifies the path to a credentials cache file. If specified, the credentials are read from this file. For example: C:\\krbccdir\\tkt.txt

Alternatively, this setting can specify the path to a directory containing a collection of credential cache files. When a directory is specified, the path must be prefixed with DIR:. For example: DIR:C:\\krbccdir\\

EncodeAuthToken:   Whether to Base64 encode the AuthToken.

This setting specifies whether AuthToken is Base64 encoded after calling Authenticate. The default value is False.

EncryptionTypes:   The encryption types used during authentication.

This setting specifies a comma separated list of encryption types used during authentication. Possible values are:

  • rc4-hmac
  • des-cbc-md5
  • aes128-cts-hmac-sha1-96

The default value is "des-cbc-md5,rc4-hmac,aes128-cts-hmac-sha1-96".

Krb5Config:   The clients Kerberos configuration file.

This setting specifies the path to the clients Kerberos configuration file (e.g., C:\path\to\krb5.conf).

When specified, the class will parse the default realm present in the configuration file (under the "libdefaults" section), along with all listed realms and KDCs (under the "realms" section). The default realm will be used during authentication, unless a domain/realm is specified in the User property. Note that in this case, the User property may be set to only a username to allow the class to use the appropriate default realm.

Assuming a default realm is found, the primary KDC associated with this realm will be used during authentication, assuming KDCHost is not specified. Additional KDCs will be used only if authentication with the primary KDC fails. Note if no KDCs are specified for a realm and "dns_lookup_kdc" is set to true in the configuration file, the class will perform a DNS query in an attempt to resolve the KDCs host name and port.

All additional realms will be stored as intermediate realms in the case cross-realm authentication is needed.

LogKerberosPackets:   Whether to include the raw Kerberos packets in PITrail output.

This settings specifies whether to include the raw Kerberos packet in the Message parameter of the PITrail event. When True the Kerberos packet will be encoded and present in the Message parameter. The default value is False. This may be enabled for troubleshooting purposes.

LogLevel:   The level of detail that is logged.

This setting controls the level of detail that is logged through the Log event. Possible values are:

0 (None) No events are logged.
1 (Info - default) Informational events are logged.
2 (Verbose) Detailed data are logged.
3 (Debug) Debug data are logged.

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

UsePlatformKerberosAPI:   Whether to use the platform Kerberos API.

This setting determines if the platform's Kerberos API is used. By default the class does not rely on any platform APIs to perform Kerberos authentication. Use of the platform API may be enabled by setting this to True. The default value is False.

Note: This functionality is only available on Windows.

UseTCP:   Whether TCP is used when establishing the connection.

This config specifies whether TCP is used as the transport protocol when establishing the connection. By default this config is False and UDP will be used.

TCPClient Config Settings

ConnectionTimeout:   Sets a separate timeout value for establishing a connection.

When set, this configuration setting allows you to specify a different timeout value for establishing a connection. Otherwise, the class will use Timeout for establishing a connection and transmitting/receiving data.

FirewallAutoDetect:   Tells the class whether or not to automatically detect and use firewall system settings, if available.

This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallHost:   Name or IP address of firewall (optional).

If a FirewallHost is given, requested connections will be authenticated through the specified firewall when connecting.

If the FirewallHost setting is set to a Domain Name, a DNS request is initiated. Upon successful termination of the request, the FirewallHost setting is set to the corresponding address. If the search is not successful, an error is returned.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPassword:   Password to be used if authentication is to be used when connecting through the firewall.

If FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the given firewall. If the authentication fails, the class .

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallPort:   The TCP port for the FirewallHost;.

The FirewallPort is set automatically when FirewallType is set to a valid value.

Note: This configuration setting is provided for use by classs that do not directly expose Firewall properties.

FirewallType:   Determines the type of firewall to connect through.

Possible values are as follows:

0No firewall (default setting).
1Connect through a tunneling proxy. FirewallPort is set to 80.
2Connect through a SOCKS4 Proxy. FirewallPort is set to 1080.
3Connect through a SOCKS5 Proxy. FirewallPort is set to 1080.
10Connect through a SOCKS4A Proxy. FirewallPort is set to 1080.

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

FirewallUser:   A user name if authentication is to be used connecting through a firewall.

If the FirewallHost is specified, the FirewallUser and FirewallPassword settings are used to connect and authenticate to the Firewall. If the authentication fails, the class .

Note: This setting is provided for use by classs that do not directly expose Firewall properties.

KeepAliveInterval:   The retry interval, in milliseconds, to be used when a TCP keep-alive packet is sent and no response is received.

When set, TCPKeepAlive will automatically be set to True. A TCP keep-alive packet will be sent after a period of inactivity as defined by KeepAliveTime. If no acknowledgment is received from the remote host, the keep-alive packet will be sent again. This configuration setting specifies the interval at which the successive keep-alive packets are sent in milliseconds. This system default if this value is not specified here is 1 second.

Note: This value is not applicable in macOS.

KeepAliveTime:   The inactivity time in milliseconds before a TCP keep-alive packet is sent.

When set, TCPKeepAlive will automatically be set to True. By default, the operating system will determine the time a connection is idle before a Transmission Control Protocol (TCP) keep-alive packet is sent. This system default if this value is not specified here is 2 hours. In many cases, a shorter interval is more useful. Set this value to the desired interval in milliseconds.

Linger:   When set to True, connections are terminated gracefully.

This property controls how a connection is closed. The default is True.

In the case that Linger is True (default), two scenarios determine how long the connection will linger. In the first, if LingerTime is 0 (default), the system will attempt to send pending data for a connection until the default IP timeout expires.

In the second scenario, if LingerTime is a positive value, the system will attempt to send pending data until the specified LingerTime is reached. If this attempt fails, then the system will reset the connection.

The default behavior (which is also the default mode for stream sockets) might result in a long delay in closing the connection. Although the class returns control immediately, the system could hold system resources until all pending data are sent (even after your application closes).

Setting this property to False forces an immediate disconnection. If you know that the other side has received all the data you sent (e.g., by a client acknowledgment), setting this property to False might be the appropriate course of action.

LingerTime:   Time in seconds to have the connection linger.

LingerTime is the time, in seconds, the socket connection will linger. This value is 0 by default, which means it will use the default IP timeout.

LocalHost:   The name of the local host through which connections are initiated or accepted.

The LocalHost setting contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the class initiate connections (or accept in the case of server classs) only through that interface.

If the class is connected, the LocalHost setting shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds.

This configuration setting must be set before a connection is attempted. It instructs the class to bind to a specific port (or communication endpoint) in the local machine.

Setting this to 0 (default) enables the system to choose a port at random. The chosen port will be shown by LocalPort after the connection is established.

LocalPort cannot be changed once a connection is made. Any attempt to set this when a connection is active will generate an error.

This configuration setting is useful when trying to connect to services that require a trusted port on the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxLineLength:   The maximum amount of data to accumulate when no EOL is found.

MaxLineLength is the size of an internal buffer, which holds received data while waiting for an EOL string.

If an EOL string is found in the input stream before MaxLineLength bytes are received, the DataIn event is fired with the EOL parameter set to True, and the buffer is reset.

If no EOL is found, and MaxLineLength bytes are accumulated in the buffer, the DataIn event is fired with the EOL parameter set to False, and the buffer is reset.

The minimum value for MaxLineLength is 256 bytes. The default value is 2048 bytes.

MaxTransferRate:   The transfer rate limit in bytes per second.

This configuration setting can be used to throttle outbound TCP traffic. Set this to the number of bytes to be sent per second. By default, this is not set and there is no limit.

ProxyExceptionsList:   A semicolon separated list of hosts and IPs to bypass when using a proxy.

This configuration setting optionally specifies a semicolon-separated list of hostnames or IP addresses to bypass when a proxy is in use. When requests are made to hosts specified in this property, the proxy will not be used. For instance:

www.google.com;www.nsoftware.com

TCPKeepAlive:   Determines whether or not the keep alive socket option is enabled.

If set to True, the socket's keep-alive option is enabled and keep-alive packets will be sent periodically to maintain the connection. Set KeepAliveTime and KeepAliveInterval to configure the timing of the keep-alive packets.

Note: This value is not applicable in Java.

TcpNoDelay:   Whether or not to delay when sending packets.

When set to True, the socket will send all data that are ready to send at once. When set to False, the socket will send smaller buffered packets of data at small intervals. This is known as the Nagle algorithm.

By default, this configuration setting is set to False.

UseIPv6:   Whether to use IPv6.

When set to 0 (default), the class will use IPv4 exclusively. When set to 1, the class will use IPv6 exclusively. To instruct the class to prefer IPv6 addresses, but use IPv4 if IPv6 is not supported on the system, this setting should be set to 2. The default value is 0. Possible values are as follows:

0 IPv4 only
1 IPv6 only
2 IPv6 with IPv4 fallback

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts.

If AbsoluteTimeout is set to True, any method that does not complete within Timeout seconds will be aborted. By default, AbsoluteTimeout is False, and the timeout is an inactivity timeout.

Note: This option is not valid for User Datagram Protocol (UDP) ports.

FirewallData:   Used to send extra data to the firewall.

When the firewall is a tunneling proxy, use this property to send custom (additional) headers to the firewall (e.g., headers for custom authentication schemes).

InBufferSize:   The size in bytes of the incoming queue of the socket.

This is the size of an internal queue in the Transmission Control Protocol (TCP)/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. In some cases, increasing the value of the InBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

OutBufferSize:   The size in bytes of the outgoing queue of the socket.

This is the size of an internal queue in the TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be sending. In some cases, increasing the value of the OutBufferSize setting can provide significant improvements in performance.

Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the class is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.
