Nexus (1.3.6OS) - Http Proxy NTLM Auth error

[Jose Coll]

Despite searching the postings, FAQ & JIRA entries I'm still unable to find an answer to this problem.

Basically, I have configured Nexus behind a corporate firewall by setting the "Administration, Server, Default Http Proxy Settings":
Proxy host: mycompany-proxy.co.uk
Proxy port: 80
and "Authentication":
Username: valid-Windows-username
Password: valid-password

and consistently get the following error message:

2009-10-14 11:51:54 INFO  [pool-1-thread-1] - o.s.n.p.s.r.RemoteR~:apacheH~ - Remote storage settings change detected, updating HttpClient...

If I omit the (optional) Authentication details, I get a similar failure condition:

Without a Proxy configuration (eg. at home with direct internet connection) everything works a treat.

Please help!

What kind of proxy server is this? NTLM v1 isn't well supported by httpclient.
