Hi, They say that Berkeley HDB is an ACID database, but does OpenLDAP support transactions ? And if yes, how do you start and commit/rollback a transaction ? Thanks Ben

User Private Groups
by Omar Hijab 17 Feb '13

17 Feb '13

Hello, Does openLDAP support User Private Groups by having memberOf return a fake self-group through some rewriting rule? Our campus has a SUN LDAP for user data that is not under our control. Our Mac and Linux clients use it for authentication. This server does not provide group management as a service. Because of this, we set up a separate openLDAP server to create/store groups. With clients bound to both servers, this works seamlessly. Because of this, we want our server to respond to memberOf queries with a fake private self-group in addition to legitimate groups the user is in, this without creating and storing private groups on our server. Is this do-able?

ACL and New users binding as anonym haveous
by cbulist 15 Feb '13

15 Feb '13

Hi, We have openldap 2.4.33 running without problem. In our first configuration we created a simple ACL in order to get access to every user. access to * by * read Then we changed it to: access to * by self write by anonymous auth by * none This ACL rules works perfectly with users that were logged by ssh before to change but users created and that never were logged after this ACL can not login. I review the openldap log file and I can see the user is trying to bind using anonymous instead of its uid. Are there any way to send the full user DN (uid=user,ou=People,dc=company,dc=com) to Ldap? Thanks in advance!

Advice request : LDAP server discovering
by Olivier 15 Feb '13

15 Feb '13

Hello, in the case I was not knocking at the right door, please accept my apologies, but as I suspect that some of you could provide some advices I post this here. In summary the issue I try to solve is "which mecanism should I deloy to route ldap requests to the right ldap server". Here is the situation : My hosts and services are distributed in 3 distinct operationnal sites (site A, site B, site C). I have three ldap servers (one on each site) that are configured to be exact replication of the others (I use openldap syncrepl in multimaster mode). On the client side (linux boxes), authentication on my hosts are based on ldap (posixaccounts/nsswitch/pam/ldap.conf and sssd). I also have deployed things such as centralized sudoer rules in ldap. At this stage, I have configured hosts so that ldap queries are sent to "the closer" ldap server first, then to another one if the first timeout : nsswitch.conf tells to query ldap (sss), and here is an extract of my ldap.conf for a host located in site A: > URI ldap://ldapA.mydom.fr ldap://ldapB.mydom.fr ldap://ldapC.mydom.fr For a host located in site C, I have declared this in ldap.conf: > URI ldap://ldapC.mydom.fr ldap://ldapB.mydom.fr ldap://ldapA.mydom.fr I would like to change that. Rather than declaring three ldap server references in configurations on the client side, I would like to implement some sort of mecanism thanks to which I would only need to declare one reference on the client side (routing ldap queries to ldap service, not to ldap servers). I see different possibilities to do that, such as setting up some sort of "heartbeat" or using some DNS trick such as multiple IN A for the same DNS RR, using sortlist option, or DNS SRV records ( _ldap._tcp. ) See: http://www-01.ibm.com/software/network/directory/library/publications/jndid… http://www.rjsystems.nl/en/2100-dns-discovery-openldap.php http://www.ietf.org/proceedings/50/I-D/ldapext-locate-05.txt http://ipamworldwide.com/bind-options/sortlist-option.html Intuitively, my preference would go to use an "_ldap._tcp" srv record, but I'm not sure if nsswitch (or clients such as sssd) would interpret this kind of DNS responses correctly (what I mean by "correctly" is "client would query an up and running ldap server found in the NS response list." Even better: "would query the faster one to respond" ). Any advice ? Experience ? Article to read ? Thanks, --- Olivier

Why is DN invalid?
by David Cunningham 13 Feb '13

13 Feb '13

Hello all, I've installed openldap 2.4.33 on OpenSUSE 11 and am trying out the perl backend. I got my certificate issues sorted out and everything seems good - until I search our university server which returns dn's such as: unbCaId=9e3454b178993cc73619606d22c7882755c9cb0d,ou=people,dc=unb,dc=ca When I return entry from search routine in perl module I get error "str2entry: entry -1 has invalid DN". I can't see anything wrong with the dn (other than it is ugly). Are there length restrictions for individual components of a dn? All similar problems I've discovered on the net are issues with commas, plus signs, quotes or unicode characters. No doubt there is something I've overlooked so please point me in the right direction. cheers, Dave C.

inconsistent sshPublicKey entries
by Michael W. Lucas 12 Feb '13

12 Feb '13

Hi, I'm running OpenLDAP 2.4.21 on FreeBSD. We do a lot of administration via phpLDAPAdmin, but I do some command-line stuff. And I've seen an inconsistency between the two in the ldapPublicKey object class. When I look in phpLDAPAdmin, my SSH keys start like this: ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAw9zmtbk8b... ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDfZ/p... If I do a ldapsearch, however, I get: sshPublicKey:: c3NoLXJzYSBBQUFBQjNOemFD.... sshPublicKey: ssh-rsa AAAAB3NzaC1 The ssh-rsa or ssh-dss string is missing from all public keys except the last one displayed. The entries without a key type have a double colon. slapcat behaves like ldapsearch. But I have to believe that the key type information is in the database, somewhere, because phpLDAPAdmin reports it's there. I didn't notice this while we used the LPK patch for our SSH servers, but we're now migrating to the official OpenSSH AuthorizedKeysCommand feature. I have a script to retrieve the keys, but my SSH servers only recognize the last key. It rejects the others because they don't have a key type attached. Any suggestions? Thanks, ==ml -- Michael W.

bdb_equality_candidates: cn=config
by Denny Schierz 12 Feb '13

12 Feb '13

hi, I get lot of messages like: <= bdb_equality_candidates: (ipHostNumber) not indexed <= bdb_equality_candidates: (ipHostNumber) not indexed <= bdb_equality_candidates: (memberUid) not indexed <= bdb_equality_candidates: (title) not indexed [...] and some more. I don't know why it happens, because I have all attributes in my index: olcDbIndex: ipHostNumber eq olcDbIndex: memberUID eq olcDbIndex: title eq [...] and also the files are there and automatically created: /var/lib/ldap/ou-company/{ ipHostNumber.bdb, memberUid.bdb, title.bdb } All index attributes are added via cn=config with my LDAP Browser. Also restarts doesn't help. I use Debian Squeeze packages in a n-way master configuration (two nodes) Any suggestions? cu denny
