Hi, I'm having a hard time getting XWiki (on CentOS 7 / Tomcat 8.0.33) to work with our companies new authenticated proxy.
First of all: in general the service user I'm using can successfully authenticate on the proxy (tested in firefox on my computer and elinks on the Linux machine). Before we had a proxy server not requiring authentication and that worked like a charm. I've already tried several approaches to make the authenticated proxy work: 1. approach via catalina.properties: http.proxyUser=USERNAME http.proxyPassword=Pass!W0rd https.proxyHost=proxy.address.com https.proxyPort=8080 http.nonProxyHosts=localhost|127.*|[::1]|several other internal domain exceptions that worked before restarted tomcat When accessing the extensions settings page of the XWiki instance (/bin/admin/XWiki/XWikiPreferences?editor=globaladmin§ion=XWiki.AddExtensions) nothing can be found. catalina.out shows 2016-08-08 15:48:16,405 [ http://10.170.64.121/xwiki/bin/admin/XWiki/XWikiPreferences?editor=globaladmin§ion=XWiki.AddExtensions] ERROR aultExtensionRepositoryManager - F org.xwiki.extension.repository.search.SearchException: Failed to search extensions based on pattern [] at org.xwiki.extension.repository.xwiki.internal.XWikiExtensionRepository.search(XWikiExtensionRepository.java:417) ~[xwiki-commons-extension-repository-xwiki-7.4.4. at org.xwiki.extension.repository.xwiki.internal.XWikiExtensionRepository.search(XWikiExtensionRepository.java:434) ~[xwiki-commons-extension-repository-xwiki-7.4.4. at org.xwiki.extension.repository.internal.DefaultExtensionRepositoryManager.search(DefaultExtensionRepositoryManager.java:381) [xwiki-commons-extension-api-7.4.4.ja at org.xwiki.extension.repository.internal.DefaultExtensionRepositoryManager.search(DefaultExtensionRepositoryManager.java:335) [xwiki-commons-extension-api-7.4.4.ja at org.xwiki.extension.repository.internal.DefaultExtensionRepositoryManager.search(DefaultExtensionRepositoryManager.java:314) [xwiki-commons-extension-api-7.4.4.ja at org.xwiki.extension.script.ExtensionManagerScriptService.search(ExtensionManagerScriptService.java:171) [xwiki-platform-extension-script-7.4.4.jar:7.4.4] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[na:1.8.0_91] [...] Caused by: java.io.IOException: Invalid answer [407] from the server when requesting [ http://extensions.xwiki.org/xwiki/rest/repository/search?start=0&number=20&q= ] at org.xwiki.extension.repository.xwiki.internal.XWikiExtensionRepository.getRESTResource(XWikiExtensionRepository.java:245) ~[xwiki-commons-extension-repository-xwi at org.xwiki.extension.repository.xwiki.internal.XWikiExtensionRepository.getRESTObject(XWikiExtensionRepository.java:295) ~[xwiki-commons-extension-repository-xwiki at org.xwiki.extension.repository.xwiki.internal.XWikiExtensionRepository.search(XWikiExtensionRepository.java:415) ~[xwiki-commons-extension-repository-xwiki-7.4.4. ... 183 common frames omitted 407 indicates an authentication issue but the correct data is in catalina.properties verified by using the same proxy settings in other applications. I also tried "domain\USERNAME" followed by a tomcat restart with the same outcome. 2. approach via separate squid instance (without authentication) that authenticates on the parent proxy: catalina.properties: http.proxyHost=localhost http.proxyPort=3128 https.proxyHost=localhost https.proxyPort=3128 http.nonProxyHosts=localhost|127.*|[::1]|several other internal domain exceptions that worked before squid.conf: http_access allow all http_port 3128 coredump_dir /var/spool/squid cache deny all dns_v4_first on cache_peer proxy.address.com parent 8080 0 no-query no-digest no-netdb-exchange default login=USERNAME:Pass!W0rd restarted tomcat restarted squid Again verified that it's working by using the squid instance in firefox and elinks. Again trying to access the extensions page of the XWiki instance no extensions can be found.
