If you want to use a Microsoft SQL Server connection without using a Data Source Name (DSN less connection), you must configure the odbcinst.ini environment variable.

If you are using a DSN connection, you must add the entry "EnableQuotedIdentifiers=1" to the ODBC DSN. If you do not add the entry, data preview and mapping run fail.

When you use a DSN connection, you can configure the DataDirect specific properties. For more information about how to configure and use the Data Direct specific properties, see the DataDirect documentation.

You can use the Microsoft SQL Server NTLM authentication on a DSN less Microsoft SQL Server connection on the Microsoft Windows platform.

If the Microsoft SQL Server table contains a UUID data type and if you are reading data from an SQL table and writing data to a flat file, the data format might not be consistent between the OLE DB and ODBC connection types.

You cannot use SSL connection on a DSN less connection. If you want to use SSL, you must use the DSN connection. Enable the Use DSN option and configure the SSL options in the odbc.ini file.

If the Microsoft SQL Server uses Kerberos authentication, you must set the GSSClient property to point to the Informatica Kerberos libraries. Use the following path and filename:

<Informatica installation directory>/server/bin/libgssapi_krb5.so.2.

Create an entry for the GSSClient property in the DSN entries section in

odbc.ini

for a DSN connection or in the SQL Server wire protocol section in

odbcinst.ini

for a connection that does not use DSN.
