To install, run odbcnds.exe. This installation program installs the driver and creates a sample data source named Default eDirectoryTM Database. This data source is configured to access the data from the default context.
Samples for Crystal Reports and Visual Basic are installed along with the driver. The install program automatically creates a Windows Start Menu entry for the sample program groups. The default installation directory is
c:\novell\odbcnds
Note that the driver requires Novell® NetWare® Client 32 or NetWare Client for NT.
The driver can be uninstalled by clicking Start Menu > Settings > Control Panel > Add/Remove Programs. Select ODBC Driver for eDirectory Read-Write Access and click Add/Remove.
The primary documentation for this driver is the guide and the HTML Help file odbcnds.chm. Other relevant files, such as release notes and samples.txt, are copied to the installation directory when the product is installed.
Sample programs are installed with the driver. There are several Crystal Reports and Visual Basic samples. These samples are documented and can be used to create your own programs.
In addition to this, the driver comes with a set of C sample programs, which can be useful by advanced developers.
If the user doesn't have necessary rights to read the object attributes, some example programs return empty values for some columns. The user should authenticate to eDirectory with Supervisor equivalent rights before running the examples.
The NDS class names USER and GROUP clash with the respective SQL keywords. These two classes are represented as UserNDS and GroupNDS, respectively.
The Microsoft Jet database engine limits the number of columns in a table to 256. If an eDirectory class contains a number of attributes that use compound syntax definitions, the class has been extended with new attributes, or the schema has been extended with many auxiliary classes, that class definition can exceed Microsoft's limit.
You can resolve the problem by creating user-defined tables. In Visual Basic, some Data Controls and Data Access Objects can be set to not use the Jet engine.
The help documentation contains more information on this topic.
Previous releases included a fix for user-defined tables that might make tables that were created with older versions of the driver obsolete.
Any definitions that list composite attributes should be changed to use the base name of the attribute.
The help documentation contains more information on this topic.
You might get a "3061, too few parameters" error while using Microsoft Jet Database Engine because Jet is parsing the query incorrectly.
You can resolve the error by setting the dbOpenSnapshot and dbSQLPassThrough flags and calling OpenRecordSet or any equivalent function.
For more information, see the sample code for Browse in Visual Basic.
While using DAO over ODBCDirect, if the time required to retrieve the result set exceeds the default or user-specified timeout interval, a Query Cancelled message might be returned by the ODBC Driver, followed by an Execution Cancelled message.
You can resolve the errors by setting the QueryTimeout value to zero as follows:
Dim conODBCDirect As DAO.ConnectionconODBCDirect.QueryTimeout = 0
The ODBC driver allows you to read and update (insert,update,delete) operations on eDirectory objects. In addition to this, the driver supports update enabled cursor and positioned update. For more details, see ODBC Driver Documentation.
