Alfresco user/pw must match AD user/pw for Map Network Drive

My end-users are using Windows XP Professional PCs and the Alfresco Community Labs 3c application is hosted on a RHEL 5.2 server. Each of the end-user Windows XP PCs are tied to Microsoft's Active Directory for user authentication during login.

Alfresco is not tied to our Active Directory setup in any way (that I am aware of). Yet, when I attempt to use the 'Map Network Drive…' function from any of the Windows XP Professional PCs, the only way this action will succeed is if the Alfresco username/password exactly matches the user's Active Directory username/password.

I don't even know where to begin diagnosing this issue. I have no idea why the Alfresco username/password would need to be identical to the Active Directory username/password. No attempt has been made to do any sort of synchronized user authentication between the two areas (Active Directory and Alfresco).

Does anyone have ANY idea why this would be? I would greatly appreciate any helpful advice or suggestions you may have. Thanks in advance!!

Hi,

I think you may have to review your config once more, there is a null pointer exception in your log.
Pay particular attention to your realms being in uppercase.
This is what it would look like (or similar) if your authentication works

You can see in the source code what happens
https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/source/ja...

I would also research if windows is at fault here, try googling "windows null sessions", gives some interesting stuff that may take you closer to solving this.

… SNIP …

To be absolutely sure, I completely uninstalled, removed and re-installed ALL of Alfresco. After doing so, I am still experiencing the same issue.

Could you go into further detail on what you mean by "Pay particular attention to your realms being in uppercase"? Does this mean all realms need to be in uppercase, or in lowercase??

I will try Google for some more answers on the Windows side.

I mean that they should be in uppercase, this is also noted in the wiki instructions. Not saying that this is the error, just something that i thought of as an easy mistake to make.

Can you confirm which files in particular the realm (in uppercase) appears in?

Here are the one's I've gotten so far:
- <alfresco install root>/tomcat/webapps/alfresco/WEB-INF/web.xml
- <alfresco install root>/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/file-servers.xml

Any others?

Instead of changing the file-servers-xml, make your changes in tomcat/shared/classes/alfresco/extension/file-servers-custom.xml, else they may get lost if the alfresco.war is redeployed. If you are missing a section, just copy from file-servers.xml and paste into file-servers-custom.xml.
Step 9 in the instructions actually refers to config before 3.0, so this should now be placed in the CIFS server config section
   
<config evaluator="string-compare" condition="CIFS Server" replace="true">
     <serverEnable enabled="true"/>
      <host name="${cifs.localname}A" domain="${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="enterprise">
     <KDC>adsrv.alfresco.org</KDC>
     <Realm>ALFRESCO.ORG</Realm>
     <Password>…</Password>
     </authenticator>

      <sessionDebug flags="Negotiate,Socket"/>
   </config>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
Note the replace="true", this makes your config override the default config.
You probably need to make more changes to this section, make sure you understand it fully.

You also have to specify realms in krb5.ini/krb5.conf, see step 6.

Thanks to your help, I think we're getting much much closer to unraveling this issue. Here's what I just did:
   1) Modified file-servers-custom.xml replace= attribute to false
   2) Added the <authenticator> section to the CIFS Server <config> section in file-servers.xml (it was only in Filesystem Security <config> section previously; now it is in both)

I now see the following debug statements in alfresco.log that look promising and I have NEVER seen then before when starting Alfresco:
DEBUG [org.alfresco.smb.protocol.auth] Logged on using principal cifs/<server>.<domain>@<realm>
DEBUG [org.alfresco.smb.protocol.auth] Enabling mechTypes :-

DEBUG [org.alfresco.smb.protocol.auth]   MS-Kerberos5

‍‍‍‍‍‍

Unfortunately, the Map Network Drive… Windows capability still does not work to the Alfresco CIFS server, AND NOW the Web Interface does not function at all either. The following is a snippet of output from alfresco.log that did not occur prior to this change. It appears that both the Web Interface and WebDAV authentication failed:

Copy the entire section
<config evaluator="string-compare" condition="CIFS Server" replace="true">
and put it into file-servers-custom.xml. And there is where the replace directive makes sense, file-servers.xml is read first and thus will never be replaced.

This will not solve your problem, but is good practice to only make config changes in the extension directory.

Now for your actual problem, I think you have it correct in you alfresco config (although not in the recommended location). The errors are now when the authentication takes place, so try searching internet on the KrbException.
If that doesn't help, next step is to use something like wireshark to dump tcp traffic to see what communication actually takes place, I don't think the logs will tell more.

Perhaps the contents of alfresco.log at startup in two different situations may be helpful.

In this situation, the Alfresco Web Interface does not function AT ALL, AND the Alfresco CIFS server CAN NOT be mapped as a network drive via Windows Explorer.

Does that provide any insight into my problem?

I see you are very active in lots of threads trying to solve this  Smiley Happy
Have a look at this for KrbException: Pre-authentication information was invalid (24), maybe just clocks out of sync?
http://java.sun.com/j2se/1.4.2/docs/guide/security/jgss/tutorials/Troubleshooting.html

This also give some info on KrbException: Identifier doesn't match expected value (906)

Add -Dsun.security.krb5.debug=true to your JAVA_OPTS and you may get more debug info in catalina.out

I will read both of those links, but any idea why the AD authentication for the Alfresco Web Interface works ONLY when the CIFS Server <authenticator> tag is commented out?

And yes, I am VERY actively seeking a remedy to my problems. All I want is an Alfresco application that authenticates via an external Active Directory server, to allow single sign-on for the Web Interface AND the CIFS server. I was previously under the impression that this is relatively simple to do.
