ClearBox Server™ v1.2 Developer's Guide


The main method of the interface. When server extension calls this method and passes it an array of TACACS attribute-value pairs found in the TACACS+ accounting packet (although this type of packets is not restricted), then server logs these attributes to the accounting logfile, every set of attributes on a new line, separating their values by a delimiter set in SetCSVOptions.

This method differs from LogTACPacketCSVEx in the way that is uses log files automatically managed by the server, while LogTACPacketCSVEx expects file handle as a parameter, and server extension is responsible for creating and managing this file.

Server extension should define logfile parameters before calling this method. It is done by making call to ILivingstonAccounting::SetLoggingOptionsEx or ILivingstonAccounting::SetLoggingOptions, inherited by ICSVAccounting interface.

Besides this, SetLoggedAttributesNames should be called to specify what attributes should be logged.

	[in] unsigned long attributesNum,
	[in] AVPAIR* inpAttributes,
	[in] TAC_AUTHORPARAMS* userInf);


[in] Number of elements in the array pointed by inpAttributes. Should not be 0.
[in] Array of TACACS attribute-value pairs that server should log. Generally, these attributes are those passed to server extension's ITACACSAccounting::ProcessAccounting implementation as inpAttributes parameter. Should not be NULL.
[in] A structure describing user associated with the accounting data passed as inpAttributes parameter. Server extension may pass NULL pointer or a pointer passed to server extension's ITACACSAccounting::ProcessAccounting implementation as userInf parameter. This parameter is needed as long as it contains values for some of pseudo-attributes listed in SetLoggedAttributesNames article except for '@time' attribute. If server extension needs not to log these pseudo-attributes, it may pass NULL as an argument.

Return Values

This method may return E_INVALIDARG if attributesNum=0, inpAttributes=NULL, SetLoggingOptions or SetLoggingOptionsEx, SetLoggedAttributesNames were not called before.

Thread Safety

This method can be called from any thread.

Memory Management

Server extension should allocate and free memory for inpAttributes and userInf parameters. If server extension uses inpAttributes and userInf parameters passed to ITACACSAccounting::ProcessAccounting implementation, then this memory is managed by the server.


Server extension may pass any TACACS+ attribute-value pairs to this method, but only attributes that were specified explicitly in call SetLoggedAttributesNames are logged. If an attribute was listed in array passed to SetLoggedAttributesNames but it's not present in the inpAttributes array, empty value is logged.

Example Code

This code uses m_pAcc as ICSVAccounting interface pointer stored in ICommonExtenderEx::InitializeEx implementation. It makes server log accounting data into the file.

//Implementation of ITACACSAccounting::ProcessAccounting

STDMETHODIMP CTest::ProcessAccounting(
	long tag, TAC_AUTHORPARAMS * accParams,
	unsigned long avSize, AVPAIR * avPairs,
	if (start==VARIANT_TRUE)
		return S_OK;
	return m_pAcc->LogTACPacketCSV(avSize,avSize,accParams);
