pom task doesn't use auth settings to resolve parent pom

In settings.xml I have defined <server>; in pom there is a <parent> pom defined and also a custom <repository>.

when trying to build this project using ant using

<artifact:dependencies
cacheDependencyRefs="false"
pathId="maven.dependency.classpath"
useScope="test">
<pom file="pom.xml"/>
</artifact:dependencies>

to resolve artifacts I get ERROR massage that the parent pom artifact could not be downloaded from my custom repository due to authentication error.

I'm attaching a patch that resolved this problem for me.
