ACL Problem?
by Nanoic Dalflanlun 03 Jun '11

03 Jun '11

I'm still seeking assistance. Something I noticed is that slapd appears to be ignoring the logging detail parameter regardless of whether I run it on Windows or CentOS. I tried setting the detail level to "any" and never had anything logged. Thanks, Nanoic ---------- Forwarded message ---------- From: Nanoic Dalflanlun <nanoic(a)gmail.com> Date: Tue, May 17, 2011 at 7:40 PM Subject: Restricted Active Directory Proxy for SaaS Vendors To: openldap-technical(a)openldap.org I am trying to setup an OpenLDAP server in my DMZ to proxy requests from Software as a Service vendors to my internal Active Directory domain. Specifically, I want to disallow anonymous access; make access read only; and restrict access to return only displayName, distinguishedName, mail, proxyAddresses, member, memberOf, mailNickname, and homeMDB. I also need to provide authentication capability for single sign on at the vendor. I don't think I have a proper understanding of OpenLDAP's ACLs, yet, so I am probably missing some things. I may even be approaching this completely wrong. I suspect I need to add "auth" access somewhere. Currently, I receive "result: 50 Insufficient access" when I try to query the OpenLDAP server. I don't have an authentication trace yet from the SaaS vendor, but it if it work like Cisco Ironport, it will try to bind to the LDAP server using the user's supplied credentials and look for a success, then switch back to using the LDAP query account.

Re: Compiling OpenLDAP against static OpenSSL libraries

Is there an IF statement missing in configure? Line 19408 specifies that RSAglue and rsaref libraries should be used without verifying whether they are needed. LIBS="-lssl -lcrypto -lRSAglue -lrsaref $LIBS" Changing this to check for rsaref would stop configure failing when using the newer versions of OpenSSL that no longer support rsaref. P.

Setting idletimeout based upon bind DN
by Mark 01 Jun '11

01 Jun '11

Is there a way to set idletimeout based upon bind DN (like the limits config option). I'd like to set an idletimeout to drop connections no longer in use, but I don't want to affect my refreshAndPersist syncrepls. Thank you, Mark

Client expects response to change-password extended operation
by Michael Smith 01 Jun '11

01 Jun '11

I noted some old correspondence about this topic in the mailing-list archives, but now it has bitten me. We have an email server in my shop (from Mirapoint) which offers users an option to change their password. It sends the password-modify extended operation, but the user's session hangs, apparently unless Mirapoint gets a response. I understand that this is non-standard behavior. But unfortunately I'm stuck with this not-very-satisfactory product. Is there any way I can tweak openLDAP to respond to the password-modify ex-op? -- -- Michael J.

slapo-rwm to change userPassword attribute into a string
by Lucio Capuani 01 Jun '11

01 Jun '11

That is, in OpenLDAP the userPassword attribute is binary, even when its content is cleartext. I would need to have an extra attribute of "String" type, containing that very password. Is it possible to achieve this by using slapo-rmw (or maybe translucent?), by creating a view that "offers" that "fake" string attribute, rather than being forced to duplicate the real source attribute into a second one, only differently encoded? Thank you so much, -- Lucio

Valid reasons to choose OpenLDAP over Oracle Directory Server for Linux clients?
by Pieter Baele 01 Jun '11

01 Jun '11

Right now, our primary LDAP systems are Sun Directory Server and AD. All Solaris boxes connect to the Directory Server, but isn't it better to set up seperate OpenLDAP servers for a Linux environment? I am also thinking about customisation. For example, integration with krb, puppet.... Greetings, Pieter Baele

Should Berkeley DB backends be reloaded occasionally?
by Mark 01 Jun '11

01 Jun '11

Back in the days of OpenLDAP 2.1 with Berkeley DB 4.1.25.3 we used to have to 'reload' out backend database occasionally as non-indexed reads would get slower and slower over time. The 'reload' entailed: - stop slapd - slapcat the contents to an .ldif file - remove the database files - slapadd the .ldif file to create a new, fresh db instance - start slapd Then our performance problems went away. Re-indexing didn't do the trick. Is such occasional re-building of the backend database recommended in OpenLDAP 2.4.25 with Berkeley DB 4.8.30? Thank you, Mark
