Advice sought regarding logging changes made to OpenLDAP server
by Philip Colmer 27 Oct '14

27 Oct '14

I've been asked to log & track changes made to our LDAP system. My initial thought was to use the auditlog overlay as it outputs to a text file, thus making it relatively straightforward to parse, but a 2009 discussion (http://www.openldap.org/lists/openldap-technical/200911/msg00092.html) suggested a potential problem, namely no logging of time and name for deletes. Replies to that discussion suggested the use of accesslog instead. However, that logs to a database which isn't really what I'm after. A 2011 discussion (http://www.openldap.org/lists/openldap-technical/201104/msg00084.html) sought answers similar to the one I'm looking for now, namely is there a way of getting changes logged into a text file? One of the replies (from Quanah) suggested ldap-stats.pl but I'm not looking for stats - I'm looking for the actual changes being made. Since both of those discussions are quite old, I was wondering if there was any up-to-date advice regarding best practice for the sort of information I'm trying to capture? Thanks. Philip

issues with schema mapping on 2.4.39 with back-sql AND oracle
by Roberto Benedetti 27 Oct '14

27 Oct '14

hello to everyone. [I already tried to send this message to the list. as a list-subscriber I couldn't see it in my inbox neither I saw it on the web list archives. I hope you did not get this message twice] * I was able to run tests against a 2.4.39 OpenLDAP server configured to make use of a MySQL server database. * I have a properly installed Oracle client and also properly configured unixODBC to query Oracle via the "isql" command. * I can see queries run against the oracle instance (although bind-values masquerade run-time queries) after issuing all the DDL and DML statements that come with the distributed software and after modifying the slapd.conf as suggested, I run into problems when starting the server (enclosed please find the complete output with debug set to "-1"): I get the following error[1] even if the query with "2" as the bind value properly works. *questions* Q1) what am I missing? have you got any hint? (if needed, I can provide further information) Q2) are the provided sample files supposed to work as-is? Q3) if the answer to Q2 is "no" but you have been able to run back-sql and Oracle, could you please share DDL and metadata? thanks for your support, roberto benedetti [1] 5447ade2 backsql_oc_get_attr_mapping(): error executing at_query "SELECT name,sel_expr,from_tbls,join_where,add_proc,delete_proc,param_order,expect_return,sel_expr_u FROM ldap_attr_mappings WHERE oc_map_id=?" for objectClass "document" with param oc_id=2 5447ade2 Return code: -1 5447ade2 <==backsql_load_schema_map() 5447ade2 backsql_db_open(): schema mapping failed, exiting 5447ade2 backend_startup_one (type=sql, suffix="dc=example,dc=com"): bi_db_open failed!

translucent overlay add an attribute to all users in a OU and subtree
by Nicolas RENAULT 26 Oct '14

26 Oct '14

Hi, (sorry for poor english) I already ask here for meta and it's working (only have the date format conversion problem but we are about to find alternative) So the ldap proxy can search for a user and provide attributes from an AD, Edir and openldap. but now I want to add attributes to the edir and openldap users search result to have as much as from a AD user (example homeDrive) I plan to use translucent to add these attributes, find that translucent cannot be used with meta so create new slapd instance. I have add base and OU into this instance I read carefully http://www.openldap.org/doc/admin24/overlays.html , and man slapo-translucent I understand that they explain how to add attributes to only one group here my questions how can I add attributes to the translucent instance to all users in an OU (and sub) ? is there another way to do what I want to do ? thanks all for responses -- Nicolas

filesystem considerations
by Julien Huon 24 Oct '14

24 Oct '14

Hello, I read a long time ago theses very interesting benchmarks : http://symas.com/mdb/microbench/july/. It seams that ext2 is the fastest filesystem for asynchronous writes. Do you think an ext4 filesystem without journalisation but with extents could be faster ? A LMBD database is a big flat file isn't it ? Extents are very interesting with that kind of files, aren't they ? Did someone try it ? Regards

Redhat LDAP Client Issues when disabling SSLv3
by Peter Boguszewski 23 Oct '14

23 Oct '14

I am running into issues on RHEL 6.x servers (mix of 6.5 and now 6.6) when attempting to disable SSLv3. I have compiled the servers with the --with-tls=openssl option and communication appears to be working well between servers to matter what I have for SSL Protocol. My problems are with the clients. For client configuration I install the openldap-clients package via yum install. Everything works as expected with this setting on the server side: olcTLSCipherSuite: HIGH:+TLSv1.2:-TLSv1.1:-TLSv1.0:+SSLv3:-SSLv2 as soon as I modify the +SSLv3 to -SSLv3 to this: olcTLSCipherSuite: HIGH:+TLSv1.2:-TLSv1.1:-TLSv1.0:-SSLv3:-SSLv2 the client no longer works. I have tried just about everything I can think of. I /can /get ldapsearch to work properly when I compile the openldap source on the client but sssd / authentication on the Red Hat side still fails. Here is the error message I am getting: 54481b75 slap_listener_activate(8): 54481b75 >>> slap_listener(ldaps://blah) 54481b75 connection_get(38): got connid=1009 54481b75 connection_read(38): checking for input on id=1009 TLS trace: SSL_accept:before/accept initialization TLS trace: SSL3 alert write:fatal:handshake failure TLS trace: SSL_accept:error in SSLv3 read client hello C TLS trace: SSL_accept:error in SSLv3 read client hello C TLS: can't accept: error:1408A0C1:SSL routines:SSL3_GET_CLIENT_HELLO:no shared cipher. 54481b75 connection_read(38): TLS accept failure error=-1 id=1009, closing 54481b75 connection_close: conn=1009 sd=38 I am assuming this has something to do with RHEL clients linking to MozNSS libraries instead of openssl but can not be sure of that. Again, to be clear - I do not change anything but the olcTLSCipherSuite entry so I do not believe it is a certificate issue. Is there a solution to LDAP auth for RHEL clients with only allowind TLSv1.2? I will gladly compile from source or use the LTB Project rpms.

Synchronizing two mirror mode clusters
by Clément OUDOT 23 Oct '14

23 Oct '14

Hi, I need to set up a backup OpenLDAP cluster and I am looking for advices on the best solutions to achieve it. The situation is: * A mirror mode cluster on one geographical site * A mirror mode cluster on another geographical site (backup site) * I would prefer not to impact configuration of main cluster * I think that full multi-master on different geographical site is not the best solution (but maybe I am totally wrong on this point) The backup site must be in sync with the main site. Here are my two ideas: * Configure a syncrepl client to main cluster on each node of the backup cluster. Question is: will not be conflicts as each node of the backup cluster is already synced with the other backup node? * Configure a LDAP proxy (back-ldap) to backup cluster, with syncrepl client to main cluster. But would back-ldap be able to write operational attributes to backup cluster? I imagine that some of you already have such needs, could you share your experience? Thanks, Clément.
