Hello, I would like to clarify my problem: My 2 LDAP servers (configured as Provider) shares the same Tree (DIT) (same part of tree): - "Server local" manages the whole tree with the structure : dc=com ou=People,dc=com uid=local_admin,ou=People,dc=com ou=Group,dc=com - "Server central" manages a database with the SAME tree structure but with other account dc=com ou=People,dc=com uid= central_admin ,ou=People,dc=com ou=Group,dc=com Is it possible to configure the "Server local" to delegates the request to "Server Central" if an account is not found locally? For example, with LDAPSEARCH: >ldapsearch -H ldaps://Server-local.com -b ou=dcom -w private -D "cn=Admin,dc=com" uid=central_admin mail -x -C => This Fails: the Serve Local does not return the "Server central" to Ldapsearch. However, if I change the DIT of "Server central" in order to be different, the Ldap delegation works. For example: - "Server central" 's DIT: dc=com2 ou=People,dc=com2 uid= central_admin ,ou=People,dc=com2 ou=Group,dc=com2 >ldapsearch -H ldaps://Server-local.com -b ou=com2 -w private -D "cn=Admin,dc=com" uid=central_admin mail -x -C => This works: Dn: uid=adminCentral,ou=People,dc=com2 Mail: admin_central(a)com2.com Ldapsearch 's traces contains referral url: "ldap_chase_v3_referral: msgid 2, url "ldaps:// Server-central.com /dc=com2 ??sub" It seems that no referral is returned if the tree are identical: it is possible to configure the Ldap server "local" to return the referral to the "central (root) if the local query fails? OpenLdap Admin Guide (version 2.4) , chapter 5.2.1.3 (olcReferral) says "This directive specifies the referral to pass back when salpd cannot find a local database to handle a request".

Well, it'd be a bug, so I've no idea what would specifically trigger it. :) I guess you could diff the slapd.conf files and see what differences exist and start from there? --Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Ulrich, You are correct, the development system is copied from the production system. The process is to perform the same ldapsearch that is producing a corrupted ldif from the development system against the production system on my management system. I then scp the ldif file over to the development system and use slapadd to load it on the development system. I have noted that slapcat on the development system does not produce the corrupted ldif file - so I do not believe my "copy production data to development system" procedure is the cause. - Frank On Thu, 12 Jan 2017 at 2:08am, Ulrich Windl wrote: > Hi! > > From your data it seems your development database is somewhat a copy of your production database, right? How did you copy? I suspect the procedure produced a currupted database (MHO).

Generic Referrals never received.

Hello, I have 2 LDAP servers: -machine 1:" localserver.domain.com" : the DIT is dn: dc=example dc: bsr-ivv objectClass: top objectClass: dcObject objectclass: organization o: AAA dn: ou=Users,dc=example objectClass: top objectClass: organizationalUnit ou: Users dn: ou=Groups,dc=example objectClass: top objectClass: organizationalUnit ou: Groups -machine 2: "centralserver.domain.com": the DIT is the SAME. and i want that request not found on "localserver.domain.com" should be delegated to "centralserver.domain.com" the configuration of "localserver.domain.com" is: dn: cn=config objectClass: olcGlobal cn: config olcArgsFile: /var/run/openldap/slapd.args olcPidFile: /var/run/openldap/slapd.pid olcTLSCACertificatePath: /etc/openldap/certs olcTLSCertificateFile: "OpenLDAP Server" olcTLSCertificateKeyFile: /etc/openldap/certs/password structuralObjectClass: olcGlobal creatorsName: cn=config olcReferral: ldaps://centralserver.domain.com olcLogLevel: -1 I use the command "ldapsearch" on "localserver" to request data about "admincentral1" that only exists on "centralserver.domain.com" machine: >ldapsearch -H ldaps://localserver.domain.com -b ou=Users,dc=bsr-ivv -w password -D "cn=Admin,dc=example" uid=admincentral1 mail -x -C -d 129 But the client "ldapsearch" does not get the refferal of "centralserver" LDAP from "localserver". I look at slap logs and ldapsearch logs but the refferal is never received. Shall i activate anything else? NB: if i use referral Objects, this works fine: i found logs like : " Jan 13 13:44:55 m-deploy slapd[24898]: send_ldap_result: referral="ldaps://centralserver.external.domain.com/ou=Users,dc=example" " but with that configuration, no referral are received by client...

Hi Beth, This is clearly noted in the slapo-ppolicy(5) man page: Note that the current IETF Password Policy proposal does not define how these operational attributes are expected to behave in a replication environment. In general, authentication attempts on a slave server only affect the copy of the operational attributes on that slave and will not affect any attributes for a user's entry on the master server. Operational attribute changes resulting from authentication attempts on a master server will usually replicate to the slaves (and also overwrite any changes that originated on the slave). These behaviors are not guaranteed and are subject to change when a formal specification emerges. The correct fix is to modify your syncrepl configuration so that those attributes are ignored by the syncrepl client. There is no patch to the code necessary.

One could also change the olcAccess on the accesslog DB to exclude problem attributes from being visible.

I would note that slaptest will report errors during conversion sometime and then note that they should be ignored, since the configuration isn't actually being used against a running slapd. Since you provide no details about the errors encountered, it's impossible to determine if it was a valid error or simply a note about the difference between the conversion process and an active slapd. You could of course take the configurations from test035 and test036 to trivially come up with working configurations to be converted to cn=config as a starting point. :) Regards, Quanah -- Quanah Gibson-Mount Product Architect Symas Corporation Packaged, certified, and supported LDAP solutions powered by OpenLDAP: <http://www.symas.com>

Chain 2 master LDap
by BENICHOU Fabrice - Contractor 12 Jan '17

12 Jan '17

Hello, I try to chain 2 LDAP master (Provider): My system is : -1 Master "central" with suffix="dc=com" : I contains ldap posix user like "adminCentral". -1 Master "local" with suffix="dc=com": It contains ldap posix user like"adminlocal". The goal is to chain request when a ldapclient ask to Master "local" : this later shall chain the request to Master "central" and get back the result to client. For example, if "uid=adminCentral,User,dc=com" is not found in Master "local" LDAP, the Master "local" LDAP shall find if this Entry exists in Master "central" 1) Is it possible for a Master, to chain via overlay with "olcDbURI" parameter to another master? I only see example where Slave (Consummer) are chaining to Master (Provider).. 2) My Master "local" is configured with TLS : it has a Master_pem certificate, and a rootCA_local.pem (used in fact to authentify a local slave for replication). How to have TLS between "Master local" and "Master central"? If the rootCA_central.pem (trust chain) is not the same that the a rootCA_local.pem, how to complete the trust chain of the Master local? My work is based on documentation : http://www.zytrax.com/books/ldap/ch7/referrals.html#chaining (7.3.5). but the full documentation is not available and I use dynamic configuration with "olc". I have also found at http://serverfault.com/questions/518407/openldap-2-4-chain-overlay-minimal-… the Chain Overlay Minimal LDIF Configuration But the delegation does not work. Anyone does have a tutorial ? My platform: Centos 7 Best regards. Fab [@@ THALES ALENIA SPACE INTERNAL @@]
