SSO from Microsoft ISA to SAP enterprise Portal

[Former Member]

Hi Gurus,

Our vendors access the Internal network using MS-ISA as proxy.The first point of authentication is MS-ISA where the Vendor needs to give his User id and Password.After that he hits the Internal Portal and is prompted for a Login again.Is there a way to set up SSO from MS-ISA to SAP EP7.0 so that there is no need for second Logon.

Thanks in Advance!

The easiest, and common way to solve this, l but not the only way is to use ISA as a proxy and use the fact that the ID of the authenticated user can be stored in an http header variable (e.g. REMOTE_USER). This HTTP header variable can then be used by the back-end SAP system (internal portal) to authenticate the user and issue an SSO2 ticket so that the authentication only needs to occur first time they access a page on the SAP system.

The use of HTTP Header variables in SAP J2ee engine is widely documented on SDN and in SAP help library.

Thanks,

You can search SAP Help Library to find instructions. I just did this and found many links, including :
