I want to run an application on my Mac that accesses a Web resource that requires a username and password, corresponding to an LDAP entry. However, the application does not have any logic to prompt me for that username/password. Isn't there a proxy tool somewhere that I can install where I can pre-enter the username/password, which will then intercept calls to the Web resource and insert the pre-entered username/password? At first, I thought SquidMan might do it, and then the Mac Web Proxy, but neither of them seem to do what I want.
