Subject [jira] [Created] (MNG-6514) Basic authentication fails if the password contains non-ascii characters

-------------------------------------------

             Summary: Basic authentication fails if the password contains non-ascii characters
                 Key: MNG-6514
                 URL: https://issues.apache.org/jira/browse/MNG-6514
             Project: Maven
          Issue Type: Bug
            Reporter: Aleksander Gjermundsen


If the username and/or password used to authenticate to Nexus contains non-ascii characters,
the authentication fails with an access denied error. After using Wireshark to investigate
the headers being sent (in my case "Ø", any non-ascii characters are replaced with "?".

To test, I have used the following configuration:
{code:java}
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
...
    <servers>
        <server>
            <id>artifactory</id>
            <username>userØ</username>
            <password>userØ</password>
        </server>
    </servers>
    ...
    <mirrors>
        <mirror>
            <id>nexus</id>
            <mirrorOf>*</mirrorOf>
            <name>Local Nexus</name>
            <url>http://localhost:8081/repository/maven-public</url>
        </mirror>
    </mirrors>
...
</settings>{code}

The settings.xml file is saved using UTF-8 encoding and it appears that Maven reads the username
and passwords correctly into strings, but Apache HttpClient do not encode the UTF-8 characters
when encoding them into base64.

I did a quick patch of Wagon to make it work for my use case, where HttpClient is configured
to encode as UTF-8. As is mentioned in MNG-5917, it is not completely clear from the standards
how these characters are supposed to be handled, but on my system both wget and the Chrome
web browser encode the characters the same way as after my patch and are able to download
files from Nexus.

Since Artifactory was used in MNG-5917, I also tested against that, but in contrast to Maven
it was not able to decode the username and password correctly, however it would be broken
without the patch anyway.
