Need help in undertsanding server certification verification by the client
by SOMA SEKHAR 05 Aug '14

05 Aug '14

Hi , I have my ca cert in a dir and I am setting the CACERTDIR option in openldap global options. *ldap_set_option(NULL, LDAP_OPT_X_TLS_CACERTDIR, <my dir path>)*. After that , I started the tls connection using '*ldap_start_tls_s*' , followed by '*ldap_bind_s*'. This worked fine. What I did not understand is that , even after removing the ca cert from that directory , ldap bind succeeds. Does it mean that certificate verification is not done for the second time by SSL_connect? I have just started on openldap and gone through the code in version 2.4 and openssl-fips-1.2 , searched in google,stackoverflow etc . Can anyone please help me with some information or pointers on this. -- Thanks&Regards, SomaSekhar.

Do you use PRAGMA case_sensitive_like? How many candidate does the "column1 LIKE '<prefix>%'" expression select?

ACL doesn't work on my Centos 6
by Dong Xi 04 Aug '14

04 Aug '14

Hi, Just set up openldap on my CentOS 6.5. Looks like very easy to set up. And it is working. However, I found ACL doesn't work as expected. I am trying to disable read access to anonymous, and give userPassword write access to self and binduser. But it doesn't work: anonymous can still read whole ldap entries, and no one except cn=Manager,dc=domain,dc=com can change userPassword. I even change following section to access to * by * none to lock down ldap, but still anonymous can read all. === access to dn.base="" by * read access to dn.base="cn=Subschema" by * read access to attrs=userPassword by self write by dn.exact="cn=binduser,dc=domain,dc=com" write by users read by anonymous auth access to * by users read by anonymous auth === to === access to * by * none === Here is the complete slapd.conf. Look like only default ACL works, whatever ACL policy I am trying to apply.

Groups in ACLs on MDB
by Johannes Löthberg 04 Aug '14

04 Aug '14

Hello, I've been trying to get using groups working in ACLs, but no matter what I do the group ACL isn't applied. It seems it might be a LMDB bug, and I'm planning on switching to hdb to see if it works there when I get the time. I've attached the olcAccess.ldif that doesn't work and the output of slapacl -D uid=kyrias,ou=users,dc=kyriasis,dc=com \ -b ou=users,dc=kyriasis,dc=com -dacl which shows that the group ACL isn't applied to the user uid=kyrias,ou=users,dc=kyriasis,dc=com even tho it is a member of the cn=admins,ou=security,dc=kyriasis,dc=com group and that the 'to *' ACL is above the other ones. -- Sincerely, Johannes Löthberg PGP Key ID: 3A9D0BB5

Password Failure for one user
by brown wrap 01 Aug '14

01 Aug '14

I am trying to track down why one user all of a sudden can't log into a machine. He can use his LDAP passwd through our network, but gets an immediate login failure on a particular machine. I can 'su' to his account, from my account using his password, but when I try to log into this machine remotely, I get the failure and it terminates the sessions. There have been no changes to the system at all. I am looking for step to troubleshoot this issue. Thanks.

Q: cn=Connection 0,cn=Connections,cn=Monitor

Hi! I'm browsing the monitor database for routine, and I founf this "Connectio 0": # Connection 0, Connections, Monitor dn: cn=Connection 0,cn=Connections,cn=Monitor monitorConnectionNumber: 0 monitorConnectionProtocol: 0 monitorConnectionOpsReceived: 4 monitorConnectionOpsExecuting: 0 monitorConnectionOpsPending: 0 monitorConnectionOpsCompleted: 4 monitorConnectionGet: 6 monitorConnectionRead: 6 monitorConnectionWrite: 0 monitorConnectionMask: L monitorConnectionListener: monitorConnectionPeerDomain: unknown monitorConnectionPeerAddress: unknown monitorConnectionLocalAddress: monitorConnectionStartTime: 19700101000000Z monitorConnectionActivityTime: 19700101000000Z Is it a bug that Start and Activity time are both unset? If the reads and writes of the connection can be counted, the timestamps could be updated as well, I guess. It's 2.4.26 here, so maybe it has been fixed meanwhile... I just saw that I have a second "connection 0": # Connection 0, Connections, Monitor dn: cn=Connection 0,cn=Connections,cn=Monitor monitorConnectionNumber: 0 monitorConnectionProtocol: 0 monitorConnectionOpsReceived: 4 monitorConnectionOpsExecuting: 0 monitorConnectionOpsPending: 0 monitorConnectionOpsCompleted: 4 monitorConnectionGet: 6 monitorConnectionRead: 6 monitorConnectionWrite: 0 monitorConnectionMask: L monitorConnectionListener: monitorConnectionPeerDomain: unknown monitorConnectionPeerAddress: unknown monitorConnectionLocalAddress: monitorConnectionStartTime: 19700101000000Z monitorConnectionActivityTime: 19700101000000Z Doing a simple quick-and-dirty test, I found out that I have multiple "Connection 0"s: sh monitor2.sh |grep '^# Connection' |sort -n SASL/EXTERNAL authentication started SASL username: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth SASL SSF: 0 # Connection 0, Connections, Monitor # Connection 0, Connections, Monitor # Connection 0, Connections, Monitor # Connection 0, Connections, Monitor # Connection 0, Connections, Monitor # Connection 0, Connections, Monitor # Connection 0, Connections, Monitor # Connection 0, Connections, Monitor # Connection 0, Connections, Monitor # Connection 1000, Connections, Monitor # Connection 1001, Connections, Monitor # Connection 1008, Connections, Monitor # Connection 1013, Connections, Monitor # Connection 1016, Connections, Monitor # Connection 1017, Connections, Monitor # Connection 1018, Connections, Monitor # Connection 1020, Connections, Monitor # Connection 1021, Connections, Monitor # Connection 1024, Connections, Monitor # Connection 1036, Connections, Monitor # Connection 1040, Connections, Monitor # Connection 1042, Connections, Monitor # Connection 1043, Connections, Monitor # Connection 1118, Connections, Monitor # Connection 1201, Connections, Monitor # Connection 1247, Connections, Monitor # Connection 1380, Connections, Monitor # Connection 14755, Connections, Monitor # Connection 14758, Connections, Monitor # Connection 15369, Connections, Monitor # Connection 15800, Connections, Monitor # Connection 15886, Connections, Monitor # Connection 16674, Connections, Monitor # Connection 20526, Connections, Monitor # Connection 20626, Connections, Monitor # Connection 21044, Connections, Monitor # Connection 21460, Connections, Monitor # Connection 21474, Connections, Monitor # Connection 21688, Connections, Monitor # Connection 25846, Connections, Monitor # Connection 30396, Connections, Monitor # Connection 30665, Connections, Monitor # Connection 31948, Connections, Monitor # Connection 35407, Connections, Monitor # Connection 35953, Connections, Monitor # Connection 36575, Connections, Monitor # Connection 36576, Connections, Monitor # Connection 36577, Connections, Monitor # Connection 36648, Connections, Monitor # Connection 50382, Connections, Monitor # Connection 50599, Connections, Monitor # Connection 50706, Connections, Monitor # Connection 51477, Connections, Monitor # Connection 55650, Connections, Monitor # Connection 55651, Connections, Monitor # Connection 56206, Connections, Monitor # Connection 61141, Connections, Monitor # Connection 61144, Connections, Monitor # Connection 61152, Connections, Monitor # Connection 61153, Connections, Monitor # Connection 61162, Connections, Monitor # Connection 61163, Connections, Monitor # Connection 61164, Connections, Monitor # Connection 61165, Connections, Monitor # Connection 61166, Connections, Monitor # Connection 61167, Connections, Monitor # Connection 61168, Connections, Monitor # Connection 62161, Connections, Monitor # Connection 65286, Connections, Monitor # Connection 67224, Connections, Monitor # Connection 70109, Connections, Monitor # Connection 70162, Connections, Monitor # Connection 70516, Connections, Monitor # Connection 70528, Connections, Monitor # Connection 70529, Connections, Monitor # Connections, Monitor Regards, Ulrich

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.

I pulled an LDIF when I realized what was happening and between 18:55 and 19:35, our LDIF went from 75MB to 45MB - so about 30MB of stuff disappeared. What happened? 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.
