Hello all!

Following these notes and SCN links is really helping me on my journey to setup SSO !

SCN community:

Important BLOGS:

--> Nice blog.  Good detail on how to use kerberos to do SSO purely for SAP GUI for windows

--> interesting,

--> SPNEGO based Single Sign-On using Secure Login Server X.509 Client Certificates

--> interesting for a mobile solution.  We can make X.509 work now on IOS if the PKCSv12 is used.  Manual step and assumed VPN but it does work.

--> just proves that with 2.0 AIX is fully supported for SSO.

--> This is the kerberos and SPNEGO for ABAP.  Great set of videos.  I think this is the easiest/simplest way for our reps and end users to get SSO for SAPGUI/ICWEB.

--> Implementing Single Sign-On with X.509 Certificates

--> full guide for SL stuff. 


--> some explanation about SSO for bsp. 

With the new NetWeaver SSO 2.0 it is now possible to configure the ABAP stack to support SPNego.

So the workaround outlined in this blog is no longer required.

NEW SP05 info

Make "kerberos" the default ticket type after the Secure login client install:
