Proxy authentication not working with WxS harvesting

[dwyera]

GeoNetwork 2.4.2 doesn't use the user supplied proxy credentials for WxS harvesting. GeoNetwork is sending it's requests through the specified proxy but doesn't appear to be supplying the credentials.

This bug was identified using both Tomcat 6 and Jetty running on Windows Server 2003.

I have reported this bug on the user forums. ​http://n2.nabble.com/Proxy-authentication-with-W-S-harvesting-SEC-UNCLASSIFIED-td3936188.html

Hi Andrew,

Try applying the changes in svn commit 5588 - sometimes the credentials were not actually being used.

Cheers, Simon

Hi Simon,

I tried your change but found one small problem. GeoNetwork now sends the proxy credentials but attempts to use NTLM authentication (because the proxy I'm using supports it) and fails with an exception. The problem is that according to the ​apache documentation, some changes need to be made to the code to support NTLM, I.e. the use of the ​UsernamePasswordCredentials class needs to be replaced with ​NTCredentials.

The way I've fixed the problem for my version is to instruct HttpClient not to use NTLM, which means the client should fall back to Basic or Digest authentication. The alternative would be to replace ​UsernamePasswordCredentials with ​NTCredentials.

I've attached my changes in a diff file.

Thanks for your help

Andrew

Thanks Andrew! I'll commit this in early January as I haven't had a chance to test it fully.
