Vince & Others getting prompted over-and-over for proxy authentication. This was specifically one of the NTLM-related proxy bugs we fixed in 7.0.1, the workaround to get it to stop prompted and work (and subsequently pickup the 7.0.1 update and work forever there after) is as follows:
=====================
If you have previously saved credentials, you will need to delete the file
stored in:
<MyEclipse Install Dir>/Common/configuration/com.genuitec.pulse2.common.http/connection.storage
This will remove any cached credentials and allow you to finish using the services you desire, as long as you don’t save credentials for your NTLM proxy server again until after the 7.0.1 update is applied.
=====================
As it turns out the bug was related to how we were retrieving the stores credentials — we were doing it wrong resulting in never-ending prompts. This was just occuring with NTLM proxies though and should be fixed with the workaround and 7.0.1 update.
