In a quick note from the fine folks at OTN, is a pointer to a new technical note that demonstrates how to create and manage custom login and sign-off pages for SSO using PHP. "If you have installed Oracle Application Server 10g Enterprise Edition and are ready to create custom SSO login and sign-off pages, then you might want to consider using PHP over the traditional PL/SQL and JSP methods. A big advantage of using PHP over PL/SQL and JSP is the ease with which the pages can be deployed and modified. With PHP, you simply open the file, make a change, and save the file. The new page and changes are picked up instantly."

The note walks you through configuring Oracle Application Server 10g to use PHP, create an apache/OHS alias for your PHP pages, creating the actual PHP login and sign-off page and finally registering the new pages with the login server.

The "single sign-on" method for authentication is becoming more and more prevolent in popular websites/installations - which is definitely a good thing. Couple that with the power and speed of using PHP to create the pages, and you have quite the winning combo. Thanks to PHP Magazine for the link...
