Microsoft IIS Oracle SSO Plug-In Does not Work with HTML Authentication The Oracle SSO Plug-In is designed not to work with other authentication modules. Authentication is either a native listener authentication module or a third-party module.

This is the only way to ensure that the .dll file is reloaded. Restarting Microsoft IIS 7.0 through the management console is not sufficient. ■ If you want multiple Oracle installations on the same home, then the ORACLE_HOME\bin PATH entry for the installation that you plan to use in conjunction with the Oracle SSO Plug-In must appear first in your PATH.
