Maven on AIX getting Authentication Denied errors
Hello all,
I'm in a very mixed environment which has me doing a variety of things on Native platforms. I have been able to get this to work reliably on Solaris, HPUX, Linux, Win32, and Win64. However, I am having some trouble with AIX.
I have a local Maven repository which requires authentication. All the other platforms work fine. AIX works fine SOME of the time. This is where it gets somewhat weird. Maven will go along pulling it's depenedencies from the maven repository just fine, then suddenly start throwing Authentication Denied errors.
I'm using the same settings.xml and the properly generated ~/.m2/settings-security.xml. Here is my servers entry in my settings.xml file:
<!-- Server passwords, requires a properly configured ~/.m2/settings-security.xml -->
<servers>
<server>
<id>pervasive</id>
<username>AUSTIN\conman</username>
<password>{jkPqcV8wN0MHmNDU3r7AAWR6ForysuXgSMRPdz7JzvA=}</password>
</server>
</servers>
As the user name would suggest, I am connecting to a Windows server which is where my Maven repository lives. I'm not using a repository manager, just a file system exported via IIS (Windows Server 2008 if that matters). That works for my entire Maven deploy except for this flaky behavior from AIX. In other words, as much as I would like to bash Microsoft, it works everywhere else. When we look at some of the logs the IT guys can scarf off of the server, it looks like AIX stops sending it's credentials across when it makes the connections.
So, to be clear. I'm jumping through these hoops:
AIX 5.3 -> IBM JVM -> Maven 2.1.0 -> Maven Security -> Microsoft IIS
Certainly nothing in that stream seems odd. :)
Here are some of the vital statistics as reported from the tools:
# mvn --version

Thanks for circling back, Jim!
My completely unfounded opinion is that you've run into an edge case
related to AIX, since relatively few of the Maven users in the world
are on AIX. I'd be very surprised if Maven gets much testing on AIX
before each new version is released.
Your workaround (ftp rather than http) seems great.

All,
The only suggestion I got regarding this was to use a Repository Manager which was really a no go in my environment.
The way I ended up fixing it was to go around the problem. I switched transport protocols from using http to ftp. That seems to be working so far.
This was as simple as modifying my settings.xml on AIX to use FTP as opposed to HTTP. This also required putting these jars in my maven/lib directory:
commons-net-2.0.jar
oro-2.0.8.jar
wagon-ftp-1.0-beta-6.jar
The one down side to this is that FTP is a bit slower than HTTP. But at least it works.
Where the original problem really is, we have no clue. But here are our theories FWIW:
1) Some bug in the http wagon that only effects AIX. Does the fact that the FTP wagon works prove this? Probably not.
2) Some bug in the IBM JDK on AIX. We have tried patching to the latest 6.0.0.125.
3) We are not on the latest and greatest AIX 5.3 but several rev's back. Maybe patching the OS would fix it?
4) Some bug in IIS on Windows 2008. We are on the latest and greatest(?) here.
5) We don't know what we are doing (hey, gotta leave that possibility open, right?)
Anyway, wanted to share my results for those Googling for issues in the future.

RE: Maven on AIX getting Authentication Denied errors

Wayne,
I knew this was the answer I was going to get. I should have prefaced with "Use a repository manager" answers need not apply. :)
The answer is I would rather not spin my wheels on that exercise as I won't use it ultimately for a variety of reasons. I suppose your hoping to prove that it is not IIS that is causing the problem, even though all of the other platforms work just fine for the exact same build. As I had mentioned we can see in the IIS logs that Maven stops sending it's credentials from the AIX system. Having not used a repository manager extensively I'm not sure what other sort of information would show up in those logs. Perhaps you could let me know what you would be looking for and I might be able to find that information otherwise?

Can you set up Nexus (or Archiva, Artifactory, etc) just to see if
that works? Then, if it does, you're all set to run a real MRM instead
of IIS/file system. ;-)
If it doesn't work, that gives some additional useful information, and
perhaps the MRM security logs might give even more info.
