CIFS and NTLM configuration

[lgr]

Hi,

My Alfresco (under linux debian) is configured for using ntlm. Webclient authentication works well.

The CIFS server is defined and worked well before ntlm configuration (using local alfresco user database) :

<host name="${localname}_A" domain="MYDOMAIN"/>
      <comment>Alfresco CIFS Server</comment>

      <!– Set to the broadcast mask for the subnet –>
      <broadcast>10.0.255.255</broadcast>

Then ntlm passthru is defined for ntlm authentication in CIFS (classic authenticator desactived):

<authenticator type="passthru">
        <Server>10.0.0.1</Server>
      </authenticator>
<!–
      <authenticator type="alfresco">
      </authenticator>
–>

Then the alfresco startup launches some errors, and the CIFS server does not start properly :

14:11:10,757 ERROR [alfresco.smb.protocol] File server configuration error, Wrong authentication setup for passthru authenticator
org.alfresco.error.AlfrescoRuntimeException: Wrong authentication setup for passthru authenticator
        at org.alfresco.filesys.server.config.ServerConfiguration.processSecurityConfig(ServerConfiguration.java:1593)

I've read some posts inthe forum, and the wiki documentation, and nothing helped me out.

Configuring debug in log4j :

log4j.logger.org.alfresco.smb.protocol=debug
log4j.logger.org.alfresco.smb.protocol.auth=debug
(this line below does not output anything, only the two lines above do)
log4j.logger.org.alfresco.passthru.auth=debug

give me some more output before the exception :

14:10:53,247 DEBUG [smb.protocol.auth] Passthru server online, [ad.mydomain.com:10.0.0.1nline:0,0]

Another information :
When re-enabling alfresco authenticator in file-servers.xml, startup goes well without errors :

<authenticator type="alfresco">
      </authenticator>

But my user is disallowed to login via passthru :

Looking into the source, it looks like doMD4UserAuthentication fails, but i don't understand why.

Does anyone know what's wrong with this configuration ?

Laurent.

Note1 : a fresh rebooted windows station made the same behaviour.
Note2 : a connection on the ftp server works well

Hi,

What authentication services have you got configured ?, in the authentication-services-context.xml file.

Cheers

Hi Gary,
actually I didn't modify that file. What was I supposed to do?

Thanks,
Alessandro

I encountered the same error under 1.3.1 Enterprise Edition.
As my SVN account will be available later, so could anyone send me the compiled class resolving this problem?
Thanks in advance.

If you defined properly the NTLMAuthenticationComponent as described in the Wiki when configuring NTML for Web and WebDAV authentication, this should also work for CIFS. Make only sure that you *do not* set the "passthru" authenticator in the file-servers-custom.xml file (delete or comment out this part and restart Alfresco).

Tested to work fine on 1.4E Preview but it should also apply to 1.3.1E or 1.4C Preview.

Hope this helps,
David
