Overlays in Consumer and provider configuration
by Uli Tehrani 30 Oct '14

30 Oct '14

Hello all, I have some questions regarding overlay configuration for consumer and provider server. It is necessary to load the same overlay modules in a consumer configuration? Is it also necessary to configure the overlay like in the provider configuration ? There are overlays that are needed only for the provider, e.g. syncprov. Others are only needed for the consumer like the chaining overlay. But for other overlays it is not that clear: Dynlist needs to be configured for both servers. But what's about dds, ppolicy and refinit? Here maybe a provider configuration is enough. Is there a simple best practise ? Thanks in advance.

syncrepl: turn consumer into a stand-alone ldap server
by Yannick Barbeaux 29 Oct '14

29 Oct '14

Hi everyone, I have configured an ldap replication based on the producer-consumer mechanism using the syncrepl module. It worked fine but at first, the ldap tree was only partially imported on the consumer because the autofs.schema was missing. It took me a few hours (days?) to find out that I had to import the autofs.ldif manually on the consumer to make it work properly: ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/autofs.ldif (that might not be the recommended way to achieve the sync but that worked). Now that I have my producer and consumer perfectly in sync, I would like to get rid of the producer server and turn my consumer into the master ldap server (that might be used later as a producer). I wonder if it is possible... I almost achieved "un-configuring" the consumer mechanism but the "ex-consumer" has now an odd behaviour : it allows me to modify the ldap tree with ldapmodify (normally impossible on consumer) but the tree is effectively modified on the ex-producer and not on the consumer itself. Yet when I perform an ldapsearch, it searches in the consumer tree, not on the producer side. To initially configure the consumer, I had injected the following ldif file: ### consumer.ldif ### #Load the syncprov module. dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: syncprov #syncrepl specific indices dn: olcDatabase={1}bdb,cn=config changetype: modify add: olcDbIndex olcDbIndex: entryUUID eq - add: olcSyncRepl olcSyncRepl: rid=001 provider=ldap://10.50.1.11 bindmethod=simple binddn="cn=synchronisator,dc=office,dc=myorg,dc=be" credentials=mysecret searchbase="dc=office,dc=myorg,dc=be" logbase="cn=accesslog" logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" schemachecking=on type=refreshAndPersist retry="60 +" syncdata=accesslog - add: olcUpdateRef olcUpdateRef: ldap://10.50.1.11 So I thought that after sync, disabling the consumer property would be as simple as unloading the syncprov module and removing the olcSyncRepl directive... this way: ### removeSyncprovModule.ldif ### dn: cn=module{0},cn=config changetype: modify delete: olcModuleLoad olcModuleLoad: {1}syncprov ### disableConsumer.ldif ### dn: olcDatabase={1}bdb,cn=config changetype: modify delete: olcSyncrepl - delete: olcUpdateRef But the ldapmodify returned an error when trying to inject that ldif file. Such operations are not allowed on the consumer. So I had no other choice than to edit the ldif manually (though it is not recommended!) to delete the corresponding directives and restart the ldap server ( /etc/ldap/slapd.d/cn=config/cn=module{0}.ldif ) Of course the server complained about wrong checksums. So I applied the method suggested on this page to fix it: http://serverfault.com/questions/499856/is-there-any-bad-thing-happens-if-i… (basically removing and re-adding the schemas+data using *slapcat* and *slapadd)* Since that, the consumer is not sync-ed with the producer anymore (good) but as I mentionned above, any attempt to modify the tree on the ex-consumer sides results in a modification on the ex-producer side and not on the consumer. Is there any easier and working way to turn a consumer into a stand-alone master ldap server? Thank you. Yannick

Access right for slapd plugins
by Ulrich Windl 29 Oct '14

29 Oct '14

Hi! I have a question: I slapd bound to access rights itself, i.e. do you have to assign some rights for e.g. the password policies for slapd to read those? What are the minimum (i.e. recommended) acess right for the password policy and the pwdPolicySubentry? Regards, Ulrich

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
