SSO to SAP using workstation password (GUI/Web)
Hello All - I am very new to this area and I am analyzing a SSO solution to implement in our company where in the User's workstation password will be the only authentication to logon to SAP. We are looking into SSO using Kerberos but we are still not clear on the solution. Below are some of the questions that I can think of from the top of my head.
1) What is the pre requisite to logon to SAP without password? AD/etc...
2) Can logon via. SAP Logon GUI be passwordless? If yes, what is the solution/technology? Also if passwordless GUI log on is possible, what will be situation where a system has more than one client? Will it prompt to enter the client number?
3) WIll SSO work across multiple landscapes like 4.7, MySAP, BW, Netweaver, etc?
I apologise ahead if I my questions are very vague. Kindly bear with me and point me to the right information, so that I can have the analysis of SSO ready for my company.
