Preparing for SAP Single Sign-On (SAP SSO)

To use SSO, at least SAP JCO 3.1.3 is required. A bug in earlier versions prevents SSO from working.

The following steps have to be executed:

1. Open the SAP software center:: https://launchpad.support.sap.com/#/softwarecenter

A login as an S-User with sufficient access rights is required.

2. Search for SAPSSOEXT and download the current version for the appropriate architecture.

   • If IFConneX is used, the version for the operating system on which Windchill is running must be downloaded.

   • For the ReleaseEngine, the version for the operating system on which the ReleaseEngine is running must be downloaded.

3. Extract the content of the .SAR file into a separate folder using the SAPCAR tool. 

Download the SAPCAR utility if you have not already done so:

Run the following command with the customized file and directory names:
SAPCAR.EXE -xvf SAPSSOEXT.SAR -R C:\Temp\sapssoext

3. Once the required folders/files are available, the directory containing the following files must be copied to the target system.
   For Windows systems, these are:

   • sapssoext.dll

   • sapcrypto.dll

   • sapgenpse.exe

   For Linux systems, these are:

   • libsapssoext.so

   • libsapcrypto.so

   • sapgenpse

The libraries that are necessary for use must be available and installed, for example, Microsoft C++ Redistributable 2010.

Info

• The path on the target system can be chosen freely. It should not contain any spaces or special characters.

• Windchill or the ReleaseEngine need read access to the files.

• The path must be communicated to Innoface, as the path must be specified in the configuration of the interface or rather the ReleaseEngine.
