Problem with overlay uniqe
by Ruud Baart 13 Aug '11

13 Aug '11

I use slapd 2.4.23 (debian package) with some overlays: syncprov, unique and valsort. I have a problem with the unique overlay. This is the unique constraint: olcUniqueURI: ldap://ou=Workstations,ou=Devices,dc=example,dc=com/?uid?sub I try to add a ldif like this: dn: uid=userabc,ou=MozillaAddressBook,ou=Users,dc=example,dc=com objectClass: person ... objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: .. ... uid: userabc ... with ldapadd I get: ldap_add: Constraint violation (19) additional info: some attributes not unique When I remove the unique constraint the ldif file is accepted. It seems to me that something is wrong: the base of olcUniqueURI is different from the base where I try to add a entry. I don't understand this. Is the olcUniqueURI wrong? -- Regards, Ruud Baart

Yes, you should make yourself familiar with ACLs for achieving degelated administration. > Also, are there decent free LDAP amin gui interface tools anyone would > recommend?

Being the author of web2ldap I'm biased anyway. Ciao, Michael.

can't get memberof filter working
by Gerardo Herzig 12 Aug '11

12 Aug '11

Hi all. Im having hard time triyng to figure out what is wrong with this ldap query: Im triyng to filter a specific user inside a specific group. Like this /usr/bin/ldapsearch -x -D ".." -w.. -b "o=Work" "(&(uniquemember=uid=gherzig,ou=People,o=Work) (memberof=cn=MailUsers,ou=Groups,o=Work))" It gets no results, but if i remove the memberof part, it works good. "(&(uniquemember=uid=gherzig,ou=People,o=Work))" as a filter gives me all the entries that users is in. What is wrong? BTW specifiyng a different basesearch is not an option, i need that base as it is. Thanks!! Gerardo

Whats the best way to design my LDAP for use by multiple apps? I need to be able to tell if a user if a member of different apps to allow access. I started by adding custom attributes for each app, boolean and such, and that works fine but somehow just doesn't feel right. Now I'm experimenting with Groups. I have a few Groups setup of objectClass groupOfNames and I've added "member"s to them...the problem is I can't seem to find an ldapsearch that returns a list of users for a particular group. What am I missing here? This query was the closest I came as it returns the list of member attributes: /usr/bin/ldapsearch -h 127.0.0.1 -x -b "dc=mydomain,dc=com" "(&(objectclass=groupOfNames)(cn=GroupA))" Perhaps I am misunderstanding that ldap can do what I'm asking...(???) Would I be better off with the custom attributes on my Users ou? I also need to consider that we need to provide access to seveal admins for maintenance, so we need to make sure one admin can't change the application access that they shouldn't be. Should we have a seperate branch for each app then??? tia, Kevin

list of replics
by Dmitriy Kirhlarov 12 Aug '11

12 Aug '11

Hi, list. Our company has some core ldap servers. Also we have many replicas from this core, all supported by different persons. I need to get the full list of these replicas. I supposed to find this information in slapd.log, with "sync" enabled, but I couldn't find any replica indicators. Could you please let me know how to find replicas information in slapd.log? WBR

chaining and referral object with two referrals
by Meike Stone 12 Aug '11

12 Aug '11

Hello, sorry for asking again. If I use the chaining overlay (slapo-chain), and I put more then one referral in the referral-object, how does the overlay behave and can I configure this? Background is, that I want put two referrals to two LDAP-Servers (multi master) and if one of them is missing, the secondary should be asked from the slapo. (http://www.openldap.org/lists/openldap-technical/201107/msg00267.html) Thanks, Meike! (Excuse me for using the mail address from my colleague last time)..

Read-only Back-SQL
by Worgan, Craig (Craig) 11 Aug '11

11 Aug '11

Hi, I have a little bit of, mainly experimental, experience configuring back-sql to connect to a PostgreSQL database. I have a requirement in front of me to expose a small table of user data in the database to an existing LDAP client. The data in the database is already in the database and managed by another application through the database directly. The LDAP API I am being asked to provide will be read-only. In other words, the data will continue to be managed by the existing management app. I foresee two problems with this approach. First, since the database table is already populated when the new ldap service is turned on, there is no data in the ldap_entries table. Is there a way to populate ldap_entries after the fact so that the records can be seen by OpenLDAP? Second, since the data is mastered by another application that goes through SQL directly, is there a way to update the ldap_entries table on the fly to reflect the additions and deletions that occur once the ldap service is up and running? Right now I am looking at writing a custom procedure to initially populate the ldap_entries table and then triggers to manage the additions and deletions from that point onward. I was just wondering if there was something in back-sql already that might provide a better solution. We are currently using OpenLDAP 2.4.21.

Multi-master setup
by Nocturn 11 Aug '11

11 Aug '11

I'm trying to set up a multi-master ldap with openldap on SL/RHEL 6.1 from the docs here: http://www.openldap.org/doc/admin24/replication.html#N-WayMulti-Master I created an ldif file with: dn: cn=config objectClass: olcGlobal cn: config olcServerID: 1 dn: olcDatabase={0}config,cn=config objectClass: olcDatabaseConfig olcDatabase: {0}config olcRootPW: *** But all attempts to import it fail, both with ldapadd as with slapadd. I think I may be getting the whole cn=config way of doing things wrong. Can anyone point me in the right direction? Thanks

XDAS, SNMP, Auditing, Architecture, Systemrequirement, Replication, Administration - Request
by Kai Pohl 11 Aug '11

11 Aug '11

Dear Sir or Madam, i have some questions about OpenLDAP 2.4.23 or 2.4.26. Does it have a XDAS interface or implementation possibility of another company? Can it use SNMP for monitoring/administration? A question of the architecture of OpenLDAP: Provide it Read-Only/Multi-Read/Write/Multi-Server System? Where can i find Requirments for the system, on which OpenLDAP should installed? My last question is about replication, which replicationforms cann be used, partitioning?

Problem in authentication when multiple CA certificates are present
by sachin mishra 10 Aug '11

10 Aug '11

LDAP authentication was working fine when I had single CA certificate at my client machine. I was using ldap_set_option(NULL, LDAP_OPT_X_TLS_CACERTFILE, tls_cacert_file)) to set the path of CA certificate. Now, there are multiple CA certificates in my certificate hosting path. I tried by reading all the files and then assign the first one using the set option above and if it fails, I perform ldap_unbind and then create a fresh request and set all the options before calling "ldap_start_tls_s". So the steps are: 1. ld = ldap_init() 2. ldap_set_option for number of options including LDAP_OPT_X_TLS_CACERTFILE which points to first file in the directory containing multiple CA certificates 3. ldap_start_tls_s(ld, NULL, NULL) 4. If step 3 is successful continue with normal operation 5. If step 3 fails, ldap_unbind (ld), start from step1 again except that LDAP_OPT_X_TLS_CACERTFILE will now have the next entry in the directory as input. Is there anything wrong in this? Is there any better approach for this? Thanks, Sachin
