OAuth issues

When you try to establish a connexion between a CLM project areas and a PTC Windchill product, you need to add an OSLC provider to your project areas, as described in the Linking Windchill Products and OSLC Project Areas section. But, when things go wrong, on Chrome, you may see a popup raising with the message: ERROR_INVALID_RESPONSE.

Note that when this happens, the URL shown in the popup is:

/oslc-windchill/services/oauth/authorize?oauth_token

If this error occurs it's because the friending between CLM and OSLC Connect for Windchill is faulty, refer to the Establishing cross-application Trust section. Remove that friending and re-run entirely the friending procedure.
