INTRODUCTION

A hotfix is available that enables user impersonation and logon tickets when you use Microsoft BizTalk Adapter 3.0 for mySAP Business Suite, which is included in Microsoft BizTalk Adapter Pack 2.0, to connect to an SAP system.

MORE INFORMATION

Support for impersonation in a SAP Secure Network Communications (SNC) environment


SAP supports impersonation by providing two connection string properties: EXTIDDATA and EXTIDTYPE. An SAP user who is using SNC can impersonate another SAP user who is identified by EXTIDDATA, such as a username or a token. The EXTIDDATA property is specified by EXTIDTYPE.

The SAP adapter supports impersonation by providing the following two new binding properties:
  • ExternalIdentificationData
  • ExternalIdentificationType

The ExternalIdentificationData binding property specifies the valid SAP user who will be impersonated. The value for this property can be a username, a token, and so on. For example, a value for this property could be in the form of domain\username.

The ExternalIdentificationType binding property indicates the kind of external identification specified for the ExternalIdentificationData binding property. The SAP adapter only supports NT as a valid value for the ExternalIdentificationType binding property.

Notes
  • You should only specify the two binding properties when you are using SNC to authenticate a user against the SAP system.
  • You need to set the UseSnc parameter in the connection URI to enable SNC.

Support for logon tickets


The SAP system issues logon tickets to enable Single Sign-On on other systems. After SAP authenticates a user, it issues a logon ticket that can be used on other systems for authentication. Therefore, users do not have to provide a user name and a password for authentication.

The SAP adapter enables adapter clients to connect to an SAP system by using logon tickets. The SAP adapter supports logon tickets by providing the following two new binding properties:
  • LogOnTicketType
  • LogOnTicketPassword

The LogOnTicketType binding property specifies the type of logon tickets, and has the following possible values:
  • The None value specifies that logon tickets will not be used for authentication. This corresponds to the default behavior of using a user name and a password for authentication.
  • The MYSAPSSO1 value specifies that the MYSAPSSO1 ticket type be used for authentication.
  • The MYSAPSSO2 value specifies that the MYSAPSSO2 ticket type be used for authentication.

The LogOnTicketPassword binding property specifies the actual ticket string for the logon ticket type.

Notes
  • Logon tickets should not be used if you are using SNC for authentication.
  • Logon tickets are not supported when you are using the SAP adapter with BizTalk Server.
