PassthruAuthenticator Null Pointer

[mliedtke]

Over the last few weeks I set up a trial version of Alfresco Enterprise 2.1.1, and had CIFS configured and working properly (Actually working really well).  As it turns out it's doubtful that we'll get the needed funding for enterprise, so today I've been setting up Community 2.1.  So far I've been able to set it up using our custom config from the Enterprise trial, but I'm having an issue with CIFS.  When I attempt to access a CIFS folder, i get the following error.

14:50:25,489 INFO  [STDOUT] 14:50:25,486 ERROR [alfresco.smb.protocol] Socket closed by remote client
14:50:25,678 INFO  [STDOUT] 14:50:25,676 ERROR [alfresco.smb.protocol] Closing session due to exception

I found this issue that looks kind of similar, but not exactly the same (http://issues.alfresco.com/browse/AR-1475)

Any ideas?

thanks,

I've had the same issue.
I've enabled passthru authentication for CIFS against a SMB server.

My file-servers-custom.xml looks like this:

The most strange thing is that it works for me in a Windows installation, but it doesn't work on a linux server.
I am a bit confused… :?

Hi,

I have exactly the same error.

Our Alfresco 2.1 instnace ran on a Linux server for 1 year without any trouble. Last wweek the message has appeared and now users can't mount CIFS access.

Did you find an answer ?
