Tarjei Skorgenes commented on MNG-4792: --------------------------------------- Having hit the same problem as you I've come to the conclusion that there are multiple layers of problems here that hinders preemptive authentication from working: 1) The configuration listed in [1] is never injected into the HttpMethodConfiguration-objects created by Plexus during configuration of HttpWagon. This is caused by the fact that the params-field in HttpMethodConfiguration is of type Properties and PropertiesConverter does not recognize the param-element. Replacing param with property fixes this part of the problem: {code:xml} <configuration><wagonProvider>httpclient</wagonProvider><httpConfiguration><put><params><property><name>http.authentication.preemptive</name><value>%b,true</value></property></params></put></httpConfiguration></configuration> {code} 2) Once properly configured Http Client ignores the preemptive-parameter completely. This is caused by the fact that the check for preemptive authentication in HTTP Client's HttpMethodDirector (line 158) is not performed on the PutMethod-object. The check is done one the HttpClientParams-object and this one has not been configured by HttpWagon to include any information about preemptive-auth. > Preemptive authentication doesn't work > -------------------------------------- > > Key: MNG-4792 > URL: http://jira.codehaus.org/browse/MNG-4792 > Project: Maven 2 & 3 > Issue Type: Bug > Components: Artifacts and Repositories > Affects Versions: 2.2.1 > Environment: Sun Java 1.6.0_21, Windows 7 > Reporter: Marcin Zajaczkowski > > It seems preemptive authentication in Maven using httpclient wagon provider > doesn't work.
