I ham trying to point my PIX 515e to a new ACS server. When I do that, the users are not able to authenticate. Error 403. The PIX and the ACS server are communicating with each other. However, I did notice that the failed authentications (or anything for that matter) are not being written to the reports in ACS. That could be the problem, but I am not too sure. Has anyone run into this problem before? Do you know how to fix it?
