Alfresco 3, CIFS with LDAP/NTLM problems

ehasting — Wed, 04 Feb 2009 19:11:21 GMT

Hello,when using alfresco with CIFS, i get this messages spamming. and the CIFS works slow.I am using LDAP with NTLM/Local (chaining) auth.First i thought it was access rights, but i am not that sure anymore.. and the errormessages does not tell me much. Its an upgrade from alfresco 2.1 to 3.0org.a

Hello,

Config : Alfresco Labs 3 Stable 1526 schema 1002 on RHEL 4 kernel 2.6.9-67.ELsmp on VMWare 3.5. 2Cpu - 8Gb ram.

NTLM with ldap synchro OK with web UI and CIFS.
When I'm trying to put some files by CIFS,I have exactly the same issue. It worked for 5 minutes, then got the error.

Hi there,

I've managed to get this issue solved for me.

I've increased the jvm value (-Xms512m -Xmx2G -XX:MaxPermSize=256m -server) and add a session timeout in file -servers.xml ( Alfresco/tomcat/webapps/alfresco/WEB-INF/classes/alfresco)

<alfresco-config area="file-servers">

   <config evaluator="string-compare" condition="CIFS Server">
          <serverEnable enabled="true"/>
      <host name="${cifs.localname}" domain="${cifs.domain}"/>
      <comment>Alfresco CIFS Server</comment>

      <!– Set to the broadcast mask for the subnet –>
      <broadcast>${cifs.broadcast}</broadcast>

      <!– Use Java socket based NetBIOS over TCP/IP and native SMB on linux –>
      <tcpipSMB platforms="linux,solaris,macosx"/>
      <netBIOSSMB platforms="linux,solaris,macosx"/>

           <!– Can be mapped to non-privileged ports, then use firewall rules to forward
                    requests from the standard ports –>
          <!–
      <tcpipSMB port="1445" platforms="linux,solaris,macosx"/>
      <netBIOSSMB sessionPort="1139" namePort="1137" datagramPort="1138" platforms="linux,solaris,macosx"/>
          –>

      <hostAnnounce interval="5"/>

      <!– Use Win32 NetBIOS interface on Windows –>
      <Win32NetBIOS/>
      <Win32Announce interval="5"/>

      <!– CIFS authentication –>
      <authenticator type="alfresco">
      </authenticator>
      <sessionTimeout>600</sessionTimeout>
<!–
      <WINS>
         <primary>1.2.3.4</primary>
         <secondary>5.6.7.8</secondary>
      </WINS>
–>
      <sessionDebug flags="Negotiate,Socket,Debug"/>
   </config>

   <config evaluator="string-compare" condition="FTP Server">
          <serverEnable enabled="true"/>

          <!– Run on a non-privileged port –>
          <!–
          <port>1121</port>
          –>

      <!– FTP authentication –>
      <authenticator type="alfresco"/>

<!–      <debug flags="File,Search,Error,Directory,Info,DataPort"/> –>
   </config>

   <config evaluator="string-compare" condition="NFS Server">
          <serverEnable enabled="false"/>
   </config>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and now my CIFS is running pretty good.

Bye

Hello,

I have the same problem

JAVA_OPTS="-Xms512m -Xmx1024m -XX:MaxPermSize=256m"
My config is a Redhat entreprise, alfresco 3 Stable, Ingres 2006 and 1,6 Gb Ram (VmWare)

The Cifs works sometimes…

Any ideas ?

ofrxnz — Tue, 24 Mar 2009 15:02:01 GMT

Same/similar problem (same error messages). Its not that cifs doesn't work, its just shaky and will work for some files or users and not for others.

Usually it works great for the first file or two, but sometimes (not always) when i queue up several it gives that error after a few

Other times it happens on a single file upload.

In any case, it can lock alfresco up so tight i need to reboot it, occasionally requiring me to clear the indexes to get cifs to work right.

It behaves like a DB lock that wont let go because it thinks it lost a packet or connection and doesn't know what to do

I dont think i have anything more to add than what is already here, but if you need/want more information on my case let me know. until then im just adding my name to the list.

I am interested in you chain config. I assume that is how you got LDAP sync work. Making LDAP-Auth load after or before NTLM?

Re: Alfresco 3, CIFS with LDAP/NTLM problems

rxm307 — Tue, 07 Apr 2009 02:47:19 GMT

I cannot get chaining working correctly, I tried with the Enterprise 3.1 Trial and the updated documentation from http://www.alfresco.com/products/ecm/enttrial/files/installing_configuring_alfresco_ecm3_1.pdf

it only ever authenitcates to the first LDAP server in the chain, I'd prefer not to use LDAP sync as the users are spread over several containers

I get the same error. I don't know what is the problems exactly. CIFS becomes unstable and windows explorer halts.
After a minutes it recovers. Sometimes it doesn't recover and it is necessary restart the computer. I have set
session timeout to 600 and this is the exception that reach.
