OpenLDAP and samba.schema for CIFS authorization

sovserg — Mon, 08 Jun 2009 22:23:23 GMT

I have OpenLDAP with samba schema and MD4 passwords (attribute: sambaNTPassword)Can I use this password for CIFS authorization?

Yes. This should work.

Thank you.
I have not found how to write MD4 password into the users' property.
Can you suggest anything?

And of the samba user utils should work.

samba utils are working
CIFS authorization does not work
I want some way to use samba passwords for CIFS authentication

Re: OpenLDAP and samba.schema for CIFS authorization

This still requires Alfresco to use a proxy (samba) to negotiate authentication for CIFS access.

I was able to integrate the samba password for alfresco in the ldap synchronization process
if anyone interested - I will send patches

Very interested to see what you did. It would be nice to document this and publish it on the wiki. If you are not up to it, I'll be more that happy to tackle that.

Re: OpenLDAP and samba.schema for CIFS authorization

morrison1977 — Tue, 12 Feb 2013 16:39:34 GMT

Hi, I've setup Alfresco Community, and have LDAP authentication working, but from what I've found LDAP authentication on an Alfresco CIFS share simply doesn't work. I'm currently in a proof of concept phase and if I can't get this working it will DOA with management. Could you share any knowledge on how I might be able to get Alfresco LDAP-CIFS authentication working? Thanks!
