Restricted Active Directory Proxy for SaaS Vendors
by Nanoic Dalflanlun 17 May '11

17 May '11

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.

AD and Openldap integration
by Darouichi, Aziz 17 May '11

17 May '11

Hi, We are in the final stage of single sign on project. We are looking to integrate Active directory with LDAP. But our MS Domain ppolicy is different than LDAP ppolicy. My question is do the policies have to be identical for the integration to work? Thanks, Aziz

Re: overlay memberof fails

Never mind, I just need to compile it using ./configure --enable-memberof, and that solved the problem.

overlay memberof fails
by JOSE L MARTINEZ-AVIAL 16 May '11

16 May '11

Hi, I've built openldap2.4.23 in my RHEL4, and it works fine. I'm able to do queries, updates, etc. But when I try to use the overlay memberof, the server does not start. It doesn't give any error message, it just fails to start. It works if I put the moduleload memberof.la, but the moment I add the overlay memberof, it just doesn't work. Any ideas about what I'm doing wrong? Thanks Jose Luis

Storing secondary gid's in openldap
by Mauro Parra 16 May '11

16 May '11

Hello, Do know of any manual/howto/doc about how to configure linux gid's thru openldap? This is, my openldap tree assigns different groups to my linux user, then i run: $ id uid=1000(mauro) gid=1000(mauro) groups=4(adm),20(dialout),24(cdrom),44(video),46(plugdev),104(lpadmin),115(admin),120(sambashare),1000(mauro) and i get all the groups I'm part of. But, I repeat the operation: $ id uid=1000(mauro) gid=1000(mauro) and I just lost all the secondary groups. All this with SLES9+openldap 2.2.3-43. Thanks in advance, Mauro -- Saludos, Mauro Parra-Miranda Consultor Senior Novell - mparra(a)novell.com openSUSE Developer - mauro(a)openSUSE.org BB PIN - 22600AE9

Re: Auth problem with openldap and nss_ldap
by Johnny PINSON 16 May '11

16 May '11

Hye, problem has been solved, thank you. Since I was using slackware without PAM, I wasn't able to auth as an ldap user. nsswitch.conf was good, nss_ldap was installed but I needed PAM for the auth part. After installing PAM and having it configured, auth is working. I now need to recompile most of my files in order to get su, ssh and other programs to work with LDAP auth (and PAM). Thank you, Johnny PINSON Le 05/10/2011 03:01 PM, Johnny PINSON a écrit : > Hey, > > I installed an openldap client and nss_ldap on a linux computer running > slackware.
