I'm in the process of implementing SSO for SAP systems. The systems
in the landscape include DEV-QA-PRD and some sandbox also.

We want to achieve Desktop SSO so that users are not asked to re-enter
access credentials (password, username). Once an user signs in one of
the systems in the landscape, he can access other systems listed in SAP logon pad (within the landscape) with other systems.

We are also not interested to use any 3rd party tools

Can someone give pointers and detailed process steps as how this can
be achieved by using SP-NEGO and Kerberos in SAP systems running under Solaris 10 with Windows clients. Note that all the clients are in MS- Windows

At the moment, we have MS-LDAP where users are being maintained for Portal.

Warm regards
