here's the Samba LDAP how-to in OO format




I have 3 points and one request:


1. The backend ldap should be bdb not ldbm (discussed very indepth on the OpenLDAP lists).

2. You should really have access controls on the LDAP database, as anyone can hen read your hashed password over the wire, unless, which I didn't notice, you only have the LDAP server listening on localhost?

3. You should be using TLS.

4. Could you do a wee conclusion, rounding everything off.


Would you mind if some of us add the 3 points above in?


Lastly, this is great document and must of taken you ages. ALl it needs is someone to start this of, then others can help.

Due you mind if I forward this to the fedora-docs list as they can do all this for us?


All good suggestions, some of which David and I have already discussed. He expressed to me that he wanted to first get it working, and then go back and work to incorporate better security such as you have indicated. Thanks for working to move this along with other doc folks in implementing them.

Comments:
Re 1. In that case why is bdb not the default in slapd.conf as provided by the FC2 openldap-servers rpm? I suspect that David simply used what was there, not changing the backend. I'm not trying to disagree - just to point out that if this is now the standing recommendation then in addition to changing the how-to it should be changed in the slapd.conf provided by the rpm.


Re 2. Definitely, although the issue is actually whether ldap directory users have query or update access to other users' hashed passwords. The over the wire comment relates to the TLS recommendation.

Re 3. Definitely.

Other points:
5. The smbldap-tools provided by the FC2 samba rpm under /usr/share/samba-n.n.n/LDAP/smbldap-tools are out of date. They should either be brought current, or removed and placed in a separate smbldap-tools rpm _included_ in FC2 distro with a pre-requisite of the perl-LDAP rpm, which in turn requires other perl- rpms. I believe this change would avoid the need for any of the CPAN steps, and allow installing the smbldap-tools from the FC2 distro.


6. The how-to should include using slappasswd to create a good password hash for inclusion within slapd.conf in lieu of the default password.

7. Yum would work just as well as apt. Perhaps alternative commands for updating and installing rpms either way would make the how-to equally as friendly to people who prefer yum.

I hope the community does remedy all those points to give this very useful document a more robust treatment of security, and make FC2 a little less complex to implement samba/ldap on.
