"Invalid path to authentication servlet" error when logging into RTC, RRC, RDNG

Technote (troubleshooting)


Attempts to login to IBM Rational Team Concert (RTC), Rational Requirements Composer (RRC) or Rational DOORS Next Generation (RDNG) results in "Invalid path to authentication servlet" error.


When launching a hyperlink from Microsoft applications (such as Microsoft Outlook, Word, Excel, or others) to the repository in Microsoft Internet Explorer 8 (and not Mozilla Firefox) the following error will occur:

HTTP 403: "Invalid path to authentication servlet"


The proxy server is returning an HTTP 403 error code due to Internet Explorer disallowing HTTP traffic on the local file system.
