Kerberos Class

Properties   Methods   Events   Config Settings   Errors  

The Kerberos class can be used to authenticate users using Kerberos 5.0.

Syntax

ipworksauth.kerberos()

Remarks

The Kerberos class implements the Kerberos protocol defined in RFC 1510 and RFC 4120. The class provides a simple interface to easily authenticate users.

Authentication

When Authenticate is called the class will attempt to authenticate the user with the Key Distribution Center (KDC). The class will communicate with the KDCHost to obtain a service ticket and populate AuthToken. The following properties are required when calling this method:

• SPN (required)
• User (required)
• Password (required)
• KDCHost (required)

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 KDCHost can be seen through the PITrail event.

Kerberos.AuthToken Property

The authentication token.

Syntax

 getAuthToken(): Uint8Array;

Default Value

""

Remarks

This property holds the authentication token.

This property will be populated after calling Authenticate. This may be used in by another entity to authenticate to the service. For instance this may be used in HTTP to authenticate to a web service.

The content of this property is a KRB_AP_REQ message. This is sometimes referred to as an "Authentication Header". It is comprised of the service ticket that was obtained from the TGS and an encrypted authenticator.

This property is read-only.

Kerberos.KDCHost Property

The domain name or IP address of the Key Distribution Center (KDC).

Syntax

 getKDCHost(): string;

 setKDCHost(KDCHost: string): void;

Default Value

""

Remarks

This property specifies the IP address (IP number in dotted internet format) or Domain Name of the Key Distribution Center (KDC).

If this property is set to a Domain Name, a DNS request is initiated and upon successful termination of the request, this property is set to the corresponding address. If the search is not successful, an error is returned.

Kerberos.KDCPort Property

The port for the Key Distribution Center (KDC).

Syntax

 getKDCPort(): number;

 setKDCPort(KDCPort: number): void;

Default Value

88

Remarks

This property specifies the port for the Key Distribution Center (KDC). The default value is 88.

Kerberos.KeytabFile Property

The Kerberos Keytab file.

Syntax

 getKeytabFile(): string;

 setKeytabFile(keytabFile: string): void;

Default Value

""

Remarks

This property specifies the path to a Kerberos Keytab file. If specified, the credentials are read from this file.

Kerberos.Password Property

The user's password.

Syntax

 getPassword(): string;

 setPassword(password: string): void;

Default Value

""

Remarks

This property specifies the user's password. This must be set before calling Authenticate.

Kerberos.SPN Property

The Service Principal Name (SPN).

Syntax

 getSPN(): string;

 setSPN(SPN: string): void;

Default Value

""

Remarks

This property specifies the Service Principal Name (SPN). This must be set before calling Authenticate.

Kerberos.Timeout Property

A timeout for the class.

Syntax

 getTimeout(): number;

 setTimeout(timeout: number): void;

Default Value

60

Remarks

If the Timeout property is set to 0, all operations will run uninterrupted until successful completion or an error condition is encountered.

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 .

Please note that by default, all timeouts are inactivity timeouts, i.e. 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.

Kerberos.User Property

The name and domain of the user to authenticate.

Syntax

 getUser(): string;

 setUser(user: string): void;

Default Value

""

Remarks

This property specifies the name and realm/domain of the user. The value specified must be in one of the following formats:

• user@domain
• domain/user

Kerberos.UseTCP Property

Whether TCP is used when establishing the connection.

Syntax

 isUseTCP(): boolean;

 setUseTCP(useTCP: boolean): void;

Default Value

FALSE

Remarks

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

Kerberos.authenticate Method

Authenticates the user.

Syntax

async kerberos.authenticate(): Promise<void>

Remarks

This method authenticates the User.

Authentication

When Authenticate is called the class will attempt to authenticate the user with the Key Distribution Center (KDC). The class will communicate with the KDCHost to obtain a service ticket and populate AuthToken. The following properties are required when calling this method:

• SPN (required)
• User (required)
• Password (required)
• KDCHost (required)

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 KDCHost can be seen through the PITrail event.

Kerberos.config Method

Sets or retrieves a configuration setting.

Syntax

async kerberos.config(configurationString : string): Promise<string>

Remarks

Config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These 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.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Kerberos.doEvents Method

Syntax

async kerberos.doEvents(): Promise<void>

Remarks

When DoEvents is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

Kerberos.interrupt Method

Interrupt the current method.

Syntax

async kerberos.interrupt(): Promise<void>

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

Kerberos.reset Method

Resets the class properties to their default values.

Syntax

async kerberos.reset(): Promise<void>

Remarks

This method resets the properties to their default values.

Kerberos.Error Event

Information about errors during data delivery.

Syntax

kerberos.on('Error', listener: (e: {readonly errorCode: number, readonly description: string}) => void )

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the class .

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

Kerberos.Log Event

Fires once for each log message.

Syntax

kerberos.on('Log', listener: (e: {readonly logLevel: number, readonly message: string, readonly logType: string}) => void )

Remarks

This event fires once for each log message generated by the class. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of the Message. 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).

LogType identifies the type of log entry. Possible values are:

• Info
• Verbose
• Debug

Kerberos.PITrail Event

Traces the messages sent to the server, and the respective replies.

Syntax

kerberos.on('PITrail', listener: (e: {readonly direction: number, readonly message: string}) => void )

Remarks

The PITrail event is useful for debugging purposes. It shows all the interaction between the client and the server. To include the raw packets set LogKerberosPackets to True.

The Message parameter contains the full text of the message. The Direction parameter shows the originator of the message:

0 (Client)	The Message originates from the client.
1 (Server)	The Message originates from the server.
2 (Info)	The Message is an informative message originating from the client software (the class code).

Config Settings (class ipworksauth.kerberos)

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.

KERBEROS 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.

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".

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.

UDP Config Settings

CaptureIPPacketInfo:   Used to capture the packet information. If this is set to true, the component will capture the IP packet information. The default value for this setting is False. Note: This setting is only available in Windows.

DelayHostResolution:   Whether the hostname is resolved when RemoteHost is set. This setting specifies whether a hostname is resolved immediately when RemoteHost is set. If true the class will resolve the hostname and the IP address will be present in the RemoteHost property. If false, the hostname is not resolved until needed by the component when a method to connect or send data is called. If desired, ResolveRemoteHost may called to manually resolve the value in RemoteHost at any time. The default value is false.

DestinationAddress:   Used to get the destination address from the packet information. If CaptureIPPacketInfo is set to true, then this will be populated with the packet's destination address when a packet is received. This information will be accessible in the DataIn event. Note: This setting is only available in Windows.

DontFragment:   Used to set the Don't Fragment flag of outgoing packets. When set to True, packets sent by the class will have the Don't Fragment flag set. The default value is False.

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 multi-homed 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 multi-homed hosts (machines with more than one IP interface).

LocalPort:   The port in the local host where the class binds. This 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; setting is useful when trying to connect to services that require a trusted port in the client side. An example is the remote shell (rsh) service in UNIX systems.

MaxPacketSize:   The maximum length of the packets that can be received. This setting specifies the maximum size of the datagrams that the class will accept without truncation.

QOSDSCPValue:   Used to specify an arbitrary QOS/DSCP setting (optional). UseConnection must be True to use this setting. This option allows you to specify an arbitrary DSCP value between 0 and 63. The default is 0. When set to the default value the component will not set a DSCP value. Note: This setting uses the qWAVE API is only available on Windows 7, Windows Server 2008 R2, and later.

QOSTrafficType:   Used to specify QOS/DSCP settings (optional). UseConnection must be True to use this setting. You may specify either the text or integer values: BestEffort (0), Background (1), ExcellentEffort (2), AudioVideo (3), Voice (4), and Control (5). Note: This setting uses the qWAVE API which is only available on Windows Vista and Windows Server 2008 or above. Note: QOSTrafficType must be set before setting Active to true.

ShareLocalPort:   If set to True, allows more than one instance of the class to be active on the same local port. This option must be set before the class is activated through the Active property or it will have no effect. The default value for this setting is False.

UseConnection:   Determines whether to use a connected socket. UseConnection specifies whether the class should use a connected socket or not. The connection is defined as an association in between the local address/port and the remote address/port. As such, this is not a connection in the traditional TCP sense. What it means is only that the class will send and receive data only to and from the specified destination. The default value for this setting is False.

UseIPv6:   Whether or not to use IPv6. By default, the component expects an IPv4 address for local and remote host properties, and will create an IPv4 socket. To use IPv6 instead, set this to True.

Socket Config Settings

AbsoluteTimeout:   Determines whether timeouts are inactivity timeouts or absolute timeouts. If AbsoluteTimeout is set to True, any method which 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 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 TCP/IP stack. You can increase or decrease its size depending on the amount of data that you will be receiving. Increasing the value of the InBufferSize setting can provide significant improvements in performance in some cases. 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. Increasing the value of the OutBufferSize setting can provide significant improvements in performance in some cases. 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.

CodePage:   The system code page used for Unicode to Multibyte translations. The default code page is Unicode UTF-8 (65001). The following is a list of valid code page identifiers: Identifier Name 037 IBM EBCDIC - U.S./Canada 437 OEM - United States 500 IBM EBCDIC - International 708 Arabic - ASMO 708 709 Arabic - ASMO 449+, BCON V4 710 Arabic - Transparent Arabic 720 Arabic - Transparent ASMO 737 OEM - Greek (formerly 437G) 775 OEM - Baltic 850 OEM - Multilingual Latin I 852 OEM - Latin II 855 OEM - Cyrillic (primarily Russian) 857 OEM - Turkish 858 OEM - Multilingual Latin I + Euro symbol 860 OEM - Portuguese 861 OEM - Icelandic 862 OEM - Hebrew 863 OEM - Canadian-French 864 OEM - Arabic 865 OEM - Nordic 866 OEM - Russian 869 OEM - Modern Greek 870 IBM EBCDIC - Multilingual/ROECE (Latin-2) 874 ANSI/OEM - Thai (same as 28605, ISO 8859-15) 875 IBM EBCDIC - Modern Greek 932 ANSI/OEM - Japanese, Shift-JIS 936 ANSI/OEM - Simplified Chinese (PRC, Singapore) 949 ANSI/OEM - Korean (Unified Hangul Code) 950 ANSI/OEM - Traditional Chinese (Taiwan;

LicenseInfo:   Information about the current license. When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information: Product: The product the license is for. Product Key: The key the license was generated from. License Source: Where the license was found (e.g., RuntimeLicense, License File). License Type: The type of license installed (e.g., Royalty Free, Single Server). Last Valid Build: The last valid build number for which the license will work.

MaskSensitive:   Whether sensitive data is masked in log messages. In certain circumstances it may be beneficial to mask sensitive data, like passwords, in log messages. Set this to true to mask sensitive data. The default is false. This setting only works on these classes: AS3Receiver, AS3Sender, Atom, Client(3DS), FTP, FTPServer, IMAP, OFTPClient, SSHClient, SCP, Server(3DS), Sexec, SFTP, SFTPServer, SSHServer, TCPClient, TCPServer.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation. When set to false, the class will use the system security libraries by default to perform cryptographic functions where applicable. Setting this setting to true tells the class to use the internal implementation instead of using the system security libraries. This setting is set to false by default on all platforms.
