We are planning to implement SSO to all SAP systems in our landscape which include BW, BI, EP, R/3, SRM etc from enterprise portal. One of the biggest challenges that we foresee in implementing SSO is to overcome the eSignature functionality that is required in many of the SAP applications on R/3 like in QM, Batch management, Plant maintenance etc. We would want the authentication to the EP for SSO to be done with the windows password. Authentication to all other systems would be based on login tickets issued by the EP. Due to very stringent password policies we cannot allow the parameters for password expiration to be changed. Neither can we change the user types.
Is it possible to activate the authentication for eSignatures to be based on the windows password. If so how?
Thanks everyone for your inputs in advance.
