Unable to auth on replica
by Marcio Merlone 02 Apr '09

02 Apr '09

Hello, I have set two Ubuntu 8.04 servers running OpenLDAP 2.4.9-0ubuntu0.8.04.2. I have set replication as per the docs. On the slave, I start with an empty /var/lib/ldap, and when I start the replica the dir is populated with the files, I am able to anon search, etc. Great, except my clients are able to auth on the provider but not on the replica. Both provider and consumer have the same acls, and the diff from one conf to another is: --- slapd.conf 2009-04-02 09:04:42.000000000 -0300 +++ slapd.conf.replica 2009-04-02 09:05:47.000000000 -0300 @@ -60,19 +61,13 @@ # 'database' directive occurs database hdb -overlay syncprov -syncprov-checkpoint 100 10 -syncprov-sessionlog 100 - -# Let the replica DN have limitless searches -limits dn.exact="cn=syncrepl,dc=a1,dc=ind" time.soft=unlimited time.hard=unlimited size.soft=unlimited size.hard=unlimited - # The base of your directory in database #1 suffix "dc=a1,dc=ind" # rootdn directive for specifying a superuser on the database.

syncrepl issue
by Oliver Henriot 02 Apr '09

02 Apr '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear list users, I have a master openldap 2.3 server which is replicated via syncrepl on half a dozen other servers (2.3 too). Due to a legacy application from which I have to import passwords once a day, the master server is stopped, erased and re-built from scratch once every day... I have noticed that all the replicas have recovered only a partial subset of the entries and the strange thing is that all the replicas have the same subset. They are all missing a few hundred entries. When I stop the replicas, erase their data and start them anew, they replicate just fine and are consistent with the master server. I was wondering : could this be due to the fact that the replicas have problems erasing the old entries and replacing them with the new set of entries? Would increasing syncprov-checkpoint <ops> and syncprov-sessionlog <size> values improve the situation? I also recall reading something about a specific configuration directive to improve delete replication but I have a feeling it was 2.4 specific... Thanks, Cheers - -- Oliver Henriot B.Sc.

open-source admin tools
by Raul Libório 31 Mar '09

31 Mar '09

Hello, I wonder which of you are the best open-source tools to maintain a database, which currently are the best if they leave ... I want to integrate environment, leave everything tied in (LDAP proxy, samba, e-mail clients, asterisk, joomla!) I see much talk of phpldapadmin, it is that all who speak it? ------ Raul Libório http://rauhmaru.blogspot.com/ rauhmarutsªhotmailºcom Linux user#4444581 Brazil "The bug is on the table."

Unable to get openldap to use active directory as ldap backend but am able to search using ldapsearch

OpenLDAP Load balancing.
by William Jojo 30 Mar '09

30 Mar '09

Under 2.4.x I would like to have 4 replicas of a master or perhaps just use 4 masters in multi-master replication. What is more important is I would like to provide one IP for LDAP queries. I have seen PEN and POUND and other types of TCP "load balancers" for simple TCP and was wondering what the OpenLDAP community recommends for doing such tasks and the implications of TLS/SSL on these tools. I thought about DNS round robin, but that doesn't take into account a missing or non-responsive server, whereas a product like PEN seems to do so. I looked at some older threads regarding this but there don't seem to be any definitive recommendation(s) by the OpenLDAP community whom I feel is the best source for such solutions. :-) Cheers, Bill

Syncrepl doesn't delete entries?

Hi all, In provider: # provider moduleload syncprov overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 index entryCSN eq index entryUUID eq and ... ldap01:~# ldapsearch -x -b 'dc=mydomain,dc=com' '(objectclass=*)' | grep javi # javi, CAT, Tecnic, mydomain.com dn: cn=javi,ou=CAT,ou=Tecnic,dc=mydomain,dc=com cn: javi # javi, CAT, Tecnic, mydomain.com dn: uid=javi,ou=CAT,ou=Tecnic,dc=domain,dc=com uid: javi cn: javi homeDirectory: /usr/local/home/javi but in the consumer: # consumer index objectclass,entryCSN,entryUUID eq syncrepl rid=125 provider=ldap://192.168.10.10:389 type=refreshAndPersist searchbase="dc=mydomain,dc=com" filter="(objectClass=*)" scope=sub attrs="*" schemachecking=off bindmethod=simple binddn="cn=Manager,dc=mydomain,dc=com" credentials=<password> ldap02:/var/lib# ldapsearch -x -b 'dc=mydomain,dc=com' '(objectclass=*)' | grep javi # javi, Tecnic, mydomain.com dn: uid=javi,ou=Tecnic,dc=mydomain,dc=com uid: javi cn: javi homeDirectory: /usr/local/home/javi # javi, CAT, Tecnic, mydomain.com dn: cn=javi,ou=CAT,ou=Tecnic,dc=mydomain,dc=com cn: javi # javi, CAT, Tecnic, mydomain.com dn: uid=javi,ou=CAT,ou=Tecnic,dc=mydomain,dc=com uid: javi cn: javi homeDirectory: /usr/local/home/javi It seems that the info in provider and consumer is diferent. If I try, for example, to change the password in provider I see that the value in consumer change automatically. Good. But it seems if I delete some entries in consumer, these changes are not reflected in consumer. ¿Where is the problem? ¿How can I debug t? -- Thanks, Jordi Espasa Clofent

mirrormode replication issues
by Jonas Haskins 29 Mar '09

29 Mar '09

Hello friends, I've been trying to setup Mirror Mode replication, using the openldap.org docs and others from googling.. and am having some interesting results. I am new to this so this has been an enlightening experience to say the least, but perhaps if someone on the list might be able to answer a few questions that would be awesome... I have 2 nodes, and want to get mirror mode running for high availibility .. and will add samba to auth ( later ) Basically it seems that mirror mode is sort of working.. i can see the syncRep talking back and forth .. However .. I cannot write to either nodes once replication is running. Below example is me trying to add a user account: error is : ( phpldapadmin reports ) LDAP said: Server is unwilling to perform Error number: 0x35 (LDAP_UNWILLING_TO_PERFORM) Description: The LDAP server refused to perform the operation. log file reports in detail: Mar 26 13:14:38 ldap01 slapd[1433]: >>> dnPrettyNormal: <cn=joepreston,dc=foobar,dc=com> Mar 26 13:14:38 ldap01 slapd[1433]: <<< dnPrettyNormal: <cn=joepreston,dc=foobar,dc=com>, <cn=joepreston,dc=foobar,dc=com> Mar 26 13:14:38 ldap01 slapd[1433]: do_add: dn (cn=joepreston,dc=foobar,dc=com) Mar 26 13:14:38 ldap01 slapd[1433]: conn=14 op=1 ADD dn="cn=joepreston,dc=foobar,dc=com" Mar 26 13:14:38 ldap01 slapd[1433]: bdb_dn2entry("cn=joepreston,dc=foobar,dc=com") Mar 26 13:14:38 ldap01 slapd[1433]: => bdb_dn2id("cn=joepreston,dc=foobar,dc=com") Mar 26 13:14:38 ldap01 slapd[1433]: <= bdb_dn2id: get failed: DB_NOTFOUND: No matching key/data pair found (-30989) Mar 26 13:14:38 ldap01 slapd[1433]: bdb_referrals: op=104 target="cn=joepreston,dc=foobar,dc=com" matched="dc=foobar,dc=com" Mar 26 13:14:38 ldap01 slapd[1433]: send_ldap_result: conn=14 op=1 p=3 Mar 26 13:14:38 ldap01 slapd[1433]: send_ldap_result: err=53 matched="" text="shadow context; no update referral" Mar 26 13:14:38 ldap01 slapd[1433]: send_ldap_response: msgid=2 tag=105 err=53 Mar 26 13:14:38 ldap01 slapd[1433]: conn=14 op=1 RESULT tag=105 err=53 text=shadow context; no update referral Mar 26 13:14:38 ldap01 slapd[1433]: daemon: activity on 1 descriptor Ma so:: text="shadow context; no update referral" using mirrormode, i should be able to write to the db correct? initally, i used ldapadd to add my ldif files on node 1 ( with syncRep commented out ) then useds slapcat/slapadd to populate the db on node 2, then uncommented syncRep on both nodes and restarted both.. ( this was because i was trying to troubleshoot the DB_NOTFOUND error above ... the result was it still errored ) however, it seems the text=shadow context; no update referral may be the real issue. am i missing something in these configs in reguards to mirrormode? logs seem to indicate syncRep is talking, and access is allowed, but no write, and if i ldap add to node 1 ( with Rep commented out ) then uncomment and restart both ( so node 1 has data but node2 does not, i can see syncRep talking, but node2 never picks up the changes ) ok whew, sorry about all of that.. any ideas? using: openldap-2.3.27 CentOS 5.2 2.6.18-92.el5 64 db-4.7.25 smbldap-tools-0.9.5-1 was going to upgrade to the latest, but there are a ton of deps , so i though i'd ask forst.. many many thanks! node1: slapd.conf # See slapd.conf(5) for details on configuration options. # This file should NOT be world readable. include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/sudo.schema include /etc/openldap/schema/samba.schema loglevel -1 # Allow LDAPv2 client connections.

configuring SSL certificate chains for slapd
by Marc Ochs 27 Mar '09

Please forgive me if this should be clear, but could someone please point me to info on how to configure a SSL certificate chain for ldaps in slapd? My CA of choice requires a chain cert and I'm having trouble finding this information in the fine documentation. Thanks much, Marc
