Because portals need to integrate with back-end resources, each with its own authentication needs, the portal often has to provide the appearance of single sign-on to the user. In this article, Chris Dunne provides a step-by-step description of his experience with building a single sign-on solution for a Web portal. He shows you how to set up an open source solution, the Central Authentication Service from Yale University, and how to extend it to authenticate to a Microsoft Active Directory infrastructure.</BLOCKQUOTE></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www-128.ibm.com/developerworks/web/library/wa-singlesign/"><div align="center"><img src="http://content9.clipmarks.com/blog_cache/www-128.ibm.com/img/9B01E1D8-9854-4725-AB81-91EF8F69F561" alt="How the CAS protocol performs authentication" /></div></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/C4D78281-679E-4EAC-A00B-6158C0ED8D46/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
