successful installation of CS ACS, services are running. However, when I try to bring up the GUI, I get this error: "Invalid administration control." What should I do?
Answer: If you have proxy server configured on the browser, you will see this message. To work around the problem, disable the proxy server completely.
By default, CiscoSecure ACS send the message "Invalid Administration Connection" when you attempt to access it with an IP address not in a permitted range. You can disable this message. To do so, select Administration Control> Session Policy and deselect the Respond to invalid IP address connections check box. ==========================================================
When I try to bring up the GUI, I get an Invalid administration control error. The installation is successful, and the services run. What is the problem?
A. This problem is usually seen when the browser has a proxy server configured. In order to fix this, disable the proxy server completely and then bring up the ACS administration screen.
