We need to have Single User name Password for Access Workstations,Servers , SAP Portal, E-Mail, Web Proxy, FTP and etc, Applications If anyone having/Knowing Windows Server Based System Concept Architecture pls discuss

Hi, You should be able to use Kerberos to enable single sign-on for must of the products you mention. But it cannot just work for "any" application. SAP is supported and most Microsoft products. Just a link to SAP, http://help.sap.com/saphelp_nwes72/helpdata/en/44/0ebf6c9b2b0d1ae10000000a114a6b/content.htm BR René

Hi , First thanks for your participation ,We have to achieve the same with IBM Lotus Notes , Cyberroam, Corporate website SAP Portal and etc We Can use the AD to achieve the same ?Gpgana

Well a quick search on those products show they support it. IBM Lotus Notes http://www.ibm.com/developerworks/lotus/library/connections-kerberos/index.html Cyberroam - I Don't know this product, but since they "say" they are better then Astaro security products, i guess they support it becase Astaro do... Corporate Website ?? IIS support's it but i don't know what else you might have... SAP Portal supports it. But you should make an effort to find out exactly what apps you need SSO to and then make a project were you analyse every program and the install /implementation guides for each product so you can design a proper solution.
