Kerberos Control
Properties Methods Events Config Settings Errors
The Kerberos control can be used to authenticate users using Kerberos 5.0.
Syntax
Kerberos
Remarks
The Kerberos control implements the Kerberos protocol defined in RFC 1510 and RFC 4120. The control provides a simple interface to easily authenticate users.
Authentication
When Authenticate is called the control will attempt to authenticate the user with the Key Distribution Center (KDC). The control will communicate with the KDCHost 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 KDCHost can be seen through the PITrail event.

AuthToken Property (Kerberos Control)
The authentication token.
Syntax
kerberoscontrol.AuthToken
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.
To read or write binary data to the property, a Variant (Byte Array) version is provided in .AuthTokenB.
This property is read-only.
Data Type
Binary String
KDCHost Property (Kerberos Control)
The domain name or IP address of the Key Distribution Center (KDC).
Syntax
kerberoscontrol.KDCHost[=string]
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.
Data Type
String
KDCPort Property (Kerberos Control)
The port for the Key Distribution Center (KDC).
Syntax
kerberoscontrol.KDCPort[=integer]
Default Value
88
Remarks
This property specifies the port for the Key Distribution Center (KDC). The default value is 88.
Data Type
Integer
KeytabFile Property (Kerberos Control)
The Kerberos Keytab file.
Syntax
kerberoscontrol.KeytabFile[=string]
Default Value
""
Remarks
This property specifies the path to a Kerberos Keytab file. If specified, the credentials are read from this file.
Data Type
String
Password Property (Kerberos Control)
The user's password.
Syntax
kerberoscontrol.Password[=string]
Default Value
""
Remarks
This property specifies the user's password. This must be set before calling Authenticate.
Data Type
String
SPN Property (Kerberos Control)
The Service Principal Name (SPN).
Syntax
kerberoscontrol.SPN[=string]
Default Value
""
Remarks
This property specifies the Service Principal Name (SPN). This must be set before calling Authenticate.
Data Type
String
Timeout Property (Kerberos Control)
A timeout for the control.
Syntax
kerberoscontrol.Timeout[=integer]
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 control will wait for the operation to complete before returning control.
The control 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 control fails with an error.
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.
Data Type
Integer
User Property (Kerberos Control)
The name and domain of the user to authenticate.
Syntax
kerberoscontrol.User[=string]

Authentication
When Authenticate is called the control will attempt to authenticate the user with the Key Distribution Center (KDC). The control will communicate with the KDCHost 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 KDCHost can be seen through the PITrail event.
Config Method (Kerberos Control)
Sets or retrieves a configuration setting.
Syntax
kerberoscontrol.Config ConfigurationString
Remarks
Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, 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.
DoEvents Method (Kerberos Control)

kerberoscontrol.DoEvents
Remarks
When DoEvents is called, the control processes any available events. If no events are available, it waits for a preset period of time, and then returns.
Interrupt Method (Kerberos Control)
Interrupt the current method.
Syntax
kerberoscontrol.Interrupt
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
Reset Method (Kerberos Control)
Resets the control properties to their default values.
Syntax
kerberoscontrol.Reset
Remarks
This method resets the properties to their default values.
Error Event (Kerberos Control)
Information about errors during data delivery.
Syntax
Sub kerberoscontrol_Error(ErrorCode As Integer, Description As String)
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.
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.
Log Event (Kerberos Control)
Fires once for each log message.
Syntax
Sub kerberoscontrol_Log(LogLevel As Integer, Message As String, LogType As String)
Remarks
This event fires once for each log message generated by the control. 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.

- Info
- Verbose
- Debug
PITrail Event (Kerberos Control)
Traces the messages sent to the server, and the respective replies.
Syntax
Sub kerberoscontrol_PITrail(Direction As Integer, Message As String)
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 control code). |
Config Settings (Kerberos Control)

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 control initiate connections (or accept in the case of server controls) only through that interface. If the control 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 control binds.
This must be set before a connection is
attempted. It instructs the control 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 control 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 control to be active on the same local port.This option must be set before the control 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 control
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 control 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. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

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 control 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 control is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small. |
