Issue/Introduction
Error when logging into Web Player: "A potentially dangerous Request. Form value was detected from the client."
Resolution
It is currently not possible to use "<" or ">" characters in passwords. In order to be able to login, the user must change the password so it does not contain these characters.
Alternatively, you can upgrade to TIBCO Spotfire version 7.5 which does allow passwords containing both "<" and ">" characters.
