Authentication

The SAP .NET Connector supports all SAP authentication options including user name, password and various single sign-on options such as Kerberos, NTLM, X.509 certificates and SAP Logon tickets. In addition, the connector makes it easy to perform SAP authentication in your application with the SAPDestination and SAPLogonDestination classes and in ASP .NET applications with the SAPLogin Form. 

We recommend you use the SAP logon classes rather than manually creating a connection string with the logon information. The SAP logon classes support getting logon information at runtime from a configuration file, SAPGUI or as another alternative, programmatically, for example from Microsoft Active Directory.
