syncrepl_del_nonpresent leading to directory implosion
by Aaron Bennett 10 Jul '14

10 Jul '14

Hi, I've got a two-node MMR setup using syncrepl running 2.4.36 with back-bdb. Last night, between 1/3 and 1/2 of the entries in our directory disappeared. Fortunately I have olcLogLeve=sync set, so I think I have a line on what happened... I see this at 4AM long of the morning before the fun started: Jul 7 04:19:30 zoot slapd[15011]: bdb(dc=clarku,dc=edu): Lock table is out of available lock entries Jul 7 04:19:30 zoot slapd[15011]: => bdb_idl_insert_key: c_get failed: Cannot allocate memory (12) Then many hours later: Jul 7 15:04:30 zoot slapd[15011]: bdb(dc=clarku,dc=edu): Lock table is out of available lock entries Jul 7 15:04:30 zoot slapd[15011]: => bdb_idl_delete_key: c_get failed: Cannot allocate memory (12) Jul 7 15:04:30 zoot slapd[15011]: null_callback : error code 0x50 Jul 7 15:04:30 zoot slapd[15011]: slap_graduate_commit_csn: removing 0x7fa33c248a80 20140707190424.188580Z#000000#001#000000 Jul 7 15:04:30 zoot slapd[15011]: syncrepl_del_nonpresent: rid=001 be_delete cn=parents_ug_students,ou=Other,ou=Groups,dc=clarku,dc=edu (80) This repeats itself several times: Jul 7 16:41:09 zoot slapd[15011]: syncprov_matchops: skipping original sid 001 Jul 7 16:41:09 zoot slapd[15011]: bdb(dc=clarku,dc=edu): Lock table is out of available lock entries Jul 7 16:41:09 zoot slapd[15011]: => bdb_idl_delete_key: c_get failed: Cannot allocate memory (12) Jul 7 16:41:09 zoot slapd[15011]: null_callback : error code 0x50 Jul 7 16:41:09 zoot slapd[15011]: slap_graduate_commit_csn: removing 0x7fa37e4b4260 20140707204059.442906Z#000000#001#000000 Jul 7 16:41:09 zoot slapd[15011]: syncrepl_del_nonpresent: rid=001 be_delete cn=parents_ug_students,ou=Other,ou=Groups,dc=clarku,dc=edu (80) Jul 7 16:52:44 zoot slapd[2179]: bdb(dc=clarku,dc=edu): Lock table is out of available lock entries Jul 7 16:52:44 zoot slapd[2179]: => bdb_idl_delete_key: c_get failed: Cannot allocate memory (12) Jul 7 16:52:44 zoot slapd[2179]: null_callback : error code 0x50 Jul 7 16:52:44 zoot slapd[2179]: slap_graduate_commit_csn: removing 0x7f74581dae70 20140707205225.029175Z#000000#001#000000 Jul 7 16:52:44 zoot slapd[2179]: syncrepl_del_nonpresent: rid=001 be_delete cn=parents_ug_students,ou=Other,ou=Groups,dc=clarku,dc=edu (80) Jul 7 16:52:44 zoot slapd[2179]: slap_queue_csn: queing 0x7f7458be8470 20140707205225.029175Z#000000#001#000000 Jul 7 16:52:44 zoot slapd[2179]: slap_graduate_commit_csn: removing 0x7f74581ad2e0 20140707205225.029175Z#000000#001#000000 Then we get (possibly unrelated) a lengthy list of nonpresent_callbacks (tons more then I list here): Jul 7 17:06:24 zoot slapd[2179]: nonpresent_callback: rid=001 present UUID 5111f346-871c-1033-8d4b-f5dbd10b8ca0, dn uid=rvenkatachalam,ou=Users,dc=clarku,dc=edu Jul 7 17:06:24 zoot slapd[2179]: nonpresent_callback: rid=001 present UUID 1e3d94e4-8ce8-1033-8d6a-f5dbd10b8ca0, dn cn=BIOL399-09-SU14,ou=Courses,ou=Groups,dc=clarku,dc=edu Jul 7 17:06:24 zoot slapd[2179]: nonpresent_callback: rid=001 present UUID 45843aa6-91b8-1033-81a9-ff6ec337b146, dn cn=MSPC3090-01-F14,ou=Courses,ou=Groups,dc=clarku,dc=edu Jul 7 17:06:24 zoot slapd[2179]: nonpresent_callback: rid=001 present UUID 4dd09f16-921b-1033-8d8e-f5dbd10b8ca0, dn cn=msit3710-01-f14,ou=DL,ou=Groups,dc=clarku,dc=edu Jul 7 17:06:24 zoot slapd[2179]: nonpresent_callback: rid=001 present UUID 0b3e8d76-9607-1033-81cf-ff6ec337b146, dn cn=acct5411-01-f14,ou=DL,ou=Groups,dc=clarku,dc=edu Jul 7 17:06:24 zoot slapd[2179]: nonpresent_callback: rid=001 present UUID a698a278-9677-1033-81ee-ff6ec337b146, dn cn=ESL0051-E1-F14,ou=Courses,ou=Groups,dc=clarku,dc=edu Jul 7 17:06:24 zoot slapd[2179]: nonpresent_callback: rid=001 present UUID ccf94c1c-979c-1033-8dc9-f5dbd10b8ca0, dn uid=dgunarajasingam,ou=Users,dc=clarku,dc=edu Followed by another lock table / del_nonpresent: Jul 7 17:06:24 zoot slapd[2179]: bdb(dc=clarku,dc=edu): Lock table is out of available lock entries Jul 7 17:06:24 zoot slapd[2179]: => bdb_idl_delete_key: c_del id failed: Cannot allocate memory (12) Jul 7 17:06:24 zoot slapd[2179]: null_callback : error code 0x50 Jul 7 17:06:24 zoot slapd[2179]: slap_graduate_commit_csn: removing 0x7f73e016cb40 20140707210614.062782Z#000000#001#000000 Jul 7 17:06:24 zoot slapd[2179]: syncrepl_del_nonpresent: rid=001 be_delete cn=parents_ug_students,ou=Other,ou=Groups,dc=clarku,dc=edu (80) Jul 7 17:06:24 zoot slapd[2179]: slap_queue_csn: queing 0x7f73e0f0eaa0 20140707210614.062782Z#000000#001#000000 Jul 7 17:06:24 zoot slapd[2179]: slap_graduate_commit_csn: removing 0x7f73e0f180c0 20140707210614.062782Z#000000#001#000000 That repeats itself @ 18:07, 18:47, 18:55.

Did I get hit by an oddball BDB/Syncrepl behavior? Do I have a bad misconfiguration in my replication setup? Thanks for your time, Aaron ---- Manager of Systems Administration Clark University ITS

Outlook LDAP Addressbook Browsing - Add ORDERING caseIgnoreOrderingMatch on CN or NAME core attributes without source code modification and re-compilition
by Richard LEGER 10 Jul '14

10 Jul '14

Hi, We currently used openldap as provided out of the box (binary) by Ubuntu 12.04 LTS. We need to enable Outlook LDAP Addressook browsing when used with our OpenLDAP current setup. According to past posts on the OpenLDAP technical mailing list, there seems to be two requirements: - Add ORDERING caseIgnoreOrderingMatch in the definition of core schema attribute CN (or Name) - Enable LDAP Virtual List View (VLV - OID: 2.16.840.1.113730.3.4.9) control and Server Side Control (SSS - OID: 1.2.840.113556.1.4.473) control on the OpenLDAP server ### Modify (or extend, or replace) definition of core schema attribute As per those posts below, it is possible to mofidy core schema attribute(s) by updating source code and recompiling openldap. http://www.openldap.org/cgi-bin/wilma_hiliter/openldap-technical/201001/msg… http://www.openldap.org/cgi-bin/wilma_hiliter/openldap-technical/201212/msg… Unfortunately this is not an option for us. Is there other way(s) via a local schema or else to modify/extend definition of OpenLDAP core attributes without modifying source code and recompiling? Via ldpamodify or via the creation of a module/overlay maybe that could be loaded via openldap configuration file slapd.conf at startup? The slapd.conf method would be our preference at the moment. As last resort, if not technically possible via slapd.conf, would using the OpenLDAP On-Line Configuration (OLC - cn=config - slapd.config) method instead allow such extend/modification of core schema attributes? If yes how? We are aware that may render our ldapserver no longer fully RFC compliant, but we need to be pragmatic here to provide an effective solution to end-users. We already use our own local LDAP schema definition anyway :-) Thank in advance for your any help/enlightenment you could provide. ### VLV and SSS Control(s) have been enabled as follow # Added the following in /etc/ldap/sldap.conf (...) moduleload sssvlv overlay sssvlv sssvlv-max 8 sssvlv-maxkeys 5 #sssvlv-maxperconn 5 <-- this option is not currently availabe in current database backend version (...) # Restart ldap server /etc/init.d/slapd restart # Check ldapsearch -x -b '' -s base '(ObjectClass=*)' + -D "uid=richard,ou=people,dc=example,dc=com" -W (...) supportedControl: 2.16.840.1.113730.3.4.9 <-- LDAP Virtual List View (VLV) supportedControl: 1.2.840.113556.1.4.473 <-- Server Side Control (SSS) (...)

Adding and attribute and editing a matchingRuleUse in the subschema
by espeake＠oreillyauto.com 10 Jul '14

10 Jul '14

On our current server running 2.4.31 we have an operational attribute in the schema labeled pwdFailureTime. I have done: slapcat -n 0 -l /tmp/<my_config>.ldif on our production server. I have also used an LDAP browser to export the schema. When I do a a slapadd -F /etc/your/config/goes/here/ -n 0 -l /tmp/<my_config>.ldif I do get the config loaded. I have confirmed that I am loading all of the same modules on both servers and that the config files match. What I don't have is the pwdFailureTime attribute which I need since it is in the data file as well, making it so I cannot import my data either. This is what the attribute looks like in the subschema: attributeTypes: ( 1.3.6.1.4.1.42.2.27.8.1.19 NAME 'pwdFailureTime' DESC 'The timestamps of the last consecutive authentication failures' EQUALITY generalizedTimeMatch ORDERING generalizedTimeOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.24 NO-USER-MODIFICATION USAGE directoryOperation ) Here is the matchingRuleUse: matchingRuleUse: ( 2.5.13.27 NAME 'generalizedTimeMatch' APPLIES ( createTimesta mp $ modifyTimestamp $ pwdChangedTime $ pwdAccountLockedTime $ pwdFailureTime $ pwdGraceUseTime $ birthDate $ hireDate $ statusDate $ openDate ) ) >From other posts that I have read I cannot edit the subschema directly and that makes sense since that would be the fastest way to kill a server. I have tried doing an ldap modify to dn: cn={4}ppolicy,cn=schema,cn=config and I get a syntax error in trying to number the attribute. The new version is 2.4.39 running on ubuntu 12.04 with 3.13 kernel.

SASL not honoring slapo-ppolicy
by Achilleas Mantzios 10 Jul '14

10 Jul '14

Hello list, I have managed successfully to setup a fully functional openldap server on FreeBSD. So far, I had success with : ppolicy, ACLs, legacy SQL exposed as LDAP, SASL authentication. My only problem thus far is combining SASL with ppolicy. When binding with classic simple authentication using -D dn, then ppolicy overlay has the expected effect. However when using SASL (SASL/SCRAM-SHA-1) with -U, while it works correctly converting uid to DN with authz-regexp, it does not seem to look for ppolicy (default or derived from pwdPolicySubentry). Moreover, enforced violations of ppolicy (e.g. failed attempted authentications >= pwdMaxFailure) when done via SASL seem to have no effect on ppolicy attributes, e.g. pwdAccountLockedTime, while they work fine when binding with simple authentication. Is there any way to overcome this? Or is ppolicy honored only via simple DN binds? -- Achilleas Mantzios Head of IT DEV IT DEPT Dynacom Tankers Mgmt

I have read the documentation and cannot figure out how to create a new dit so I can add the module I need. If you can be more specific on what I should be looking for that would be great. But no where have I found that points how to create the cn=module{0} dit so it can be populated. I don't know maybe I'm asking the wrong questions. from the docs 5.2.2. cn=module If support for dynamically loaded modules was enabled when configuring slapd, cn=module entries may be used to specify sets of modules to load. Module entries must have the olcModuleList objectClass. I don't have a cn=module dit, how do I create it?

Here is what the cn=config directory looks like. As you can see there is no olcDatabase={x}module.ldif file so my question is how do you create one. olcDatabase={2}hdb.ldif olcDatabase={1}monitor.ldif olcDatabase={0}config.ldif cn=schema olcDatabase={-1}frontend.ldif cn=schema.ldif I created this compliant ldif dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: {0}/usr/lib64/openldap/memberof.la but when I try an use ldapmodify -Y EXTERNAL -H ldapi:/// -v -f ldapMdynalist.ldif I get ldap_initialize( ldapi:///??base ) SASL/EXTERNAL authentication started SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth SASL SSF: 0 add olcModuleLoad: {0}/usr/lib64/openldap/memberof.la modifying entry "cn=module{0},cn=config" ldap_modify: No such object (32) matched DN: cn=config So how do you create a ldif in cn=config. I've read the docs but it is not clear to me how to do this. Once the file is created I'm sure ldapmodify will work. Do I just touch the file?

I've been messing with LDAP for the past couple of days, and following various online tutorials on how to create an addressbook for Thunderbird in openldap. Sure, this isn't too difficult, and I have it working as a proof of concept. I can use phpldapadmin to create new entries in my addressbook, and these will show up in Thunderbird's addressbook. I've also spent the day reading most of the openldap admin guide (250 pages), which eventually I noticed is missing section E, where I'm sure something simple like this would appear. However, now I want to organise the addresses into groups. eg, say we have the following staff: John Smith works in the head office and is the CEO Ann Johnson works in the head office and is a general admin person Mary Brown works in the branch office and is the state manager Jane Martin works in the branch office and is a general admin person I want everybody to be listed in a People group... I want all four people listed in a Staff group... I want John Smith and Mary Brown in a Managers group I want John Smith and Ann Johnson in a Head Office group I want Mary Brown and Jane Martin in a Branch Office group So, I could do this like this: dn: dc=example,dc=com objectClass: top objectClass: dcObject objectClass: organization o: My Organization dc: example dn: ou=People,dc=example,dc=com objectClass: top objectClass: organizationalUnit ou: People description: All the people dn: ou=Staff,dc=example,dc=com objectClass: organizationalUnit objectClass: top ou: Staff dn: cn=John Smith+mail=jsmith(a)example.com,ou=People,dc=example,dc=com objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: mozillaAbPersonAlpha givenName: John sn: Smith cn: John Smitih mail: jsmith(a)example.com etc for other people Then I can configure the groups like this: dn: cn=Managers,dc=example,dc=com cn: Managers of example.com objectclass: groupofNames member: cn=John Smith+mail=jsmith(a)example.com,ou=People,dc=example,dc=com member: cn=Mary Brown+mail=mbrown(a)example.com,ou=People,dc=example,dc=com However, thunderbird doesn't seem to have any smart way to show this group... So, I thought, maybe I could duplicate the "People" and put complete addressbook records into the Managers ou, but then it complains that the same CN already exists, besides the fact that this just seems like a kludge, and not a very "nice" way to achieve this. PS, the context is to try and replace MS Outlook with Mozilla Thunderbird. With email in IMAP4, that works well. I can share the calendar from thunderbird to iphones/android phones with http://calendarserver.org/. Now I'm just trying to resolve the "shared contacts" issue, which is currently solved by copying (at login) a pst file from a share to the local users profile, and having that configured to open in outlook (add pst data file). I'd prefer to replace all that with ldap, since thunderbird supports ldap for an addressbook, and it would then update immediately (instead of after next login). Also, long term it would be useful to use ldap for other web based login authentication, squid proxy auth, and/or even windows authentication, but, one step/problem at a time. Thank you for any advise or suggestions, or pointers to documentation. Regards, Adam -- Adam Goryachev Website Managers www.websitemanagers.com.au

sizelimit issue in openldap + lmdb environment
by Ajit K Jena 08 Jul '14

Hi, We have been openldap user for long time with BDB backend. Now I am trying to migrate to LMDB backend. In our environment we are trying to enforce a limit specified below: sizelimit size.soft=54 size.hard=100 size.unchecked=150 This works properly in the BDB environment. In the LMDB environment we cant get even one query answered. We get error 11 (administrative limit exceeded). The query is for (objectclass=*) for a single user (uid=xxx). Has anyone see this before ? The property "sizelimit" is concerned with ldap. How is it getting affected with change of storage backend ? Pl guide me as to how to fix this problem. --ajit --------------------------------------------------------------------- Ajit K.
