Kerberos Component
Properties Methods Events Config Settings Errors
The Kerberos component can be used to authenticate users using Kerberos 5.0.
Syntax
TipaKerberos
Remarks
The Kerberos component implements the Kerberos protocol defined in RFC 1510 and RFC 4120. The component provides a simple interface to easily authenticate users.
Authentication
When Authenticate is called the component will attempt to authenticate the user with the Key Distribution Center (KDC). The component 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 Component)
The authentication token.
Syntax
__property String AuthToken = { read=FAuthToken }; __property DynamicArray<Byte> AuthTokenB = { read=FAuthTokenB };
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.
Data Type
Byte Array
KDCHost Property (Kerberos Component)
The domain name or IP address of the Key Distribution Center (KDC).
Syntax
__property String KDCHost = { read=FKDCHost, write=FSetKDCHost };
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 Component)
The port for the Key Distribution Center (KDC).
Syntax
__property int KDCPort = { read=FKDCPort, write=FSetKDCPort };
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 Component)
The Kerberos Keytab file.
Syntax
__property String KeytabFile = { read=FKeytabFile, write=FSetKeytabFile };
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 Component)
The user's password.
Syntax
__property String Password = { read=FPassword, write=FSetPassword };
Default Value
""
Remarks
This property specifies the user's password. This must be set before calling Authenticate.
Data Type
String
SPN Property (Kerberos Component)
The Service Principal Name (SPN).
Syntax
__property String SPN = { read=FSPN, write=FSetSPN };
Default Value
""
Remarks
This property specifies the Service Principal Name (SPN). This must be set before calling Authenticate.
Data Type
String
Timeout Property (Kerberos Component)
This property includes the timeout for the component.
Syntax
__property int Timeout = { read=FTimeout, write=FSetTimeout };
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 component will wait for the operation to complete before returning control.
The component 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 component raises an exception.
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.
Data Type
Integer
User Property (Kerberos Component)
The name and domain of the user to authenticate.
Syntax
__property String User = { read=FUser, write=FSetUser };
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
Data Type
String
UseTCP Property (Kerberos Component)
Whether TCP is used when establishing the connection.
Syntax
__property bool UseTCP = { read=FUseTCP, write=FSetUseTCP };
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.
Data Type
Boolean
Authenticate Method (Kerberos Component)
Authenticates the user.
Syntax
void __fastcall Authenticate();
Remarks
This method authenticates the User.
Authentication
When Authenticate is called the component will attempt to authenticate the user with the Key Distribution Center (KDC). The component 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 Component)
Sets or retrieves a configuration setting.
Syntax
String __fastcall Config(String ConfigurationString);
Remarks
Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.
These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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 Component)
This method processes events from the internal message queue.
Syntax
void __fastcall DoEvents();
Remarks
When DoEvents is called, the component processes any available events. If no events are available, it waits for a preset period of time, and then returns.
Interrupt Method (Kerberos Component)
This method interrupts the current method.
Syntax
void __fastcall Interrupt();
Remarks
If there is no method in progress, Interrupt simply returns, doing nothing.
Reset Method (Kerberos Component)
Resets the component properties to their default values.
Syntax
void __fastcall Reset();
Remarks
This method resets the properties to their default values.
Error Event (Kerberos Component)
Fired when information is available about errors during data delivery.
Syntax
typedef struct { int ErrorCode; String Description; } TipaKerberosErrorEventParams; typedef void __fastcall (__closure *TipaKerberosErrorEvent)(System::TObject* Sender, TipaKerberosErrorEventParams *e); __property TipaKerberosErrorEvent OnError = { read=FOnError, write=FOnError };
Remarks
The Error event is fired in case of exceptional conditions during message processing. Normally the component raises an exception.
The ErrorCode parameter contains an error code, and the Description parameter 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 Component)
Fires once for each log message.
Syntax
typedef struct { int LogLevel; String Message; String LogType; } TipaKerberosLogEventParams; typedef void __fastcall (__closure *TipaKerberosLogEvent)(System::TObject* Sender, TipaKerberosLogEventParams *e); __property TipaKerberosLogEvent OnLog = { read=FOnLog, write=FOnLog };
Remarks
This event fires once for each log message generated by the component. 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
PITrail Event (Kerberos Component)
Traces the messages sent to the server, and the respective replies.
Syntax
typedef struct { int Direction; String Message; } TipaKerberosPITrailEventParams; typedef void __fastcall (__closure *TipaKerberosPITrailEvent)(System::TObject* Sender, TipaKerberosPITrailEventParams *e); __property TipaKerberosPITrailEvent OnPITrail = { read=FOnPITrail, write=FOnPITrail };
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 component code). |
Config Settings (Kerberos Component)
The component 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 component, access to these internal properties is provided through the Config method.KERBEROS Config Settings
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\\
- rc4-hmac
- des-cbc-md5
- aes128-cts-hmac-sha1-96
The default value is "des-cbc-md5,rc4-hmac,aes128-cts-hmac-sha1-96".
When specified, the component 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 component 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 component 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.
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).
Note: This functionality is only available on Windows.
UDP Config Settings
The default value for this setting is False.
Note: This configuration setting is available only in Windows.
The default value is false.
Note: This configuration setting is available only in Windows.
In multihomed hosts (machines with more than one IP interface), setting LocalHost to the value of an interface will make the component initiate connections (or accept in the case of server components) only through that interface.
If the component 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).
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.
Note: This configuration setting uses the qWAVE API and is available only on Windows 7, Windows Server 2008 R2, and later.
Note: This configuration setting uses the qWAVE API and is available only on Windows Vista and Windows Server 2008 or above.
Note: QOSTrafficType must be set before setting Active to True.
The default value for this setting is False.
The default value for this setting is False.
Socket Config Settings
Note: This option is not valid for User Datagram Protocol (UDP) ports.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the InBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.
Some TCP/IP implementations do not support variable buffer sizes. If that is the case, when the component is activated the OutBufferSize reverts to its defined size. The same happens if you attempt to make it too large or too small.

FIPS mode can be enabled by setting the UseFIPSCompliantAPI configuration setting to true. This is a static setting that applies to all instances of all components of the toolkit within the process. It is recommended to enable or disable this setting once before the component has been used to establish a connection. Enabling FIPS while an instance of the component is active and connected may result in unexpected behavior.
For more details, please see the FIPS 140-2 Compliance article.
Note: This setting is applicable only on Windows.
Note: Enabling FIPS compliance requires a special license; please contact sales@nsoftware.com for details.
Setting this configuration setting to true tells the component to use the internal implementation instead of using the system security libraries.
This setting is set to false by default on all platforms.
