I have access problem on CIFS

richard_tsai

Hi!
I have access problem on CIFS. The problem can be re-produced as the following scenario:

1. Start alfresco 2.0
2. net use \\xxxx_a\alfresco password /user:xxx\richard

17:00:48,500 DEBUG [smb.protocol.auth] NT Session setup from user=htcmfgadmin, p

   ‍‍‍‍‍‍‍

3. start \\xxxx_a\alfresco. Then, we can browse alfresco by Windows file explorer without problem.
4. Stop Alfresco 2.0
5. Start Alfresco 2.0
6. start \\xxxx_a\alfresco. oops…
Windows XP pops up a window to show
"\\xxxx_a is not accessiable. You may not have permission…., access denied"
start \\xxxx_a. Windows XP pops up a logon challenge window.

Greetings,
I am having a similar issue. Could you please post your file-servers.xml file.
I'd like to see how you have it configured. I have :

   <config evaluator="string-compare" condition="Filesystem Security">

  <authenticator type="alfresco">

  </authenticator>

   </config>‍‍‍‍‍‍‍

Its not working out too well for me.

Thanks,
Jim

I get the feeling that configuration doesn't work (its the same as mine). When I get some time during the day (when I get paid to look at this stuff), I'll post a link to how I think it is 'supposed' to be, although I could never get that working.

Since I configured multiple domain servers to authenticate users, I think that's why my CIFS didn't work.
After I removed xxxdc2 in servers property, CIFS works fine.

ntlm-authentication-context.xml

  …
        <property name="servers">
            <value>xxxdc1,xxxdc2</value>
        </property>

We have multiple domains in my company, so I modified NTLMAuthenticationComponentImpl to
authenticate users. If user login Alfresco via browser, Alfresco will authenticate by invocation of authenticateLocal()
and it works fine for user from different domains. If user login Alfresco by windows file explorer,
Alfresco will authenticate user by authentePassthru(), but it failed to authenticate user.
I tried to open new sessions from PassthruServers and created new authentication token, but it's useless.
Anyway, I'm still investigating this issue. However, I just wonder if I'm doing simple thing by complex way.
It should be very common to have multiple domains in a company.

Hi!

Per Andy's comment:

http://forums.alfresco.com/viewtopic.php?t=4329

The chaining authentication does not handle CIFS and MD4 hashes at the moment. It could find the first implementation that supports MD4 and report that hash. CIFS only tries agaisnt one hash.

An LDAP implementation could provide the MD4 hash …. but do you want to make password hashes readable by anyone/guest from your LDAP server (as you have not authenticated when you need to go and get them - or you would need to use the default ldap username and credentials). It is possible to implement the appropriate methods on top of the LDAP auth impl if you want.

The only other alternative is to keep hashes after people log in (in memory or persisted). But this requires a good login to build the cache (CIFS access only is not allowed) and the potential for the hash to go out of sync.

Overall it is best if CIFS can validate a Kerberos ticket at the moment.
It could useMD4 hash (from plain text would be possible) + NTLM, Kerberos, NTLM passthrough.

It is possible we could support Kerberos against other kerberos servers but I do not know the details here.

Basically NTLM is a bit of a pain.

It looks like, currently, Alfresco cannot authenticate multiple domain users for CIFS. Could any Alfresco folks confirm this? We do need this feature in our Alfresco system.

BTW, there's an alternative to replace my customization in NTLMAuthenticationComponentImpl.java by chaining authentication.

Hi

NTLM authentication on its ownw supports multiple domains.

Chaining authentication does not support NTLM. It could support using the first NTLM instance in the chain: it could not try more than one as far as I undrestand it.
