Virtual list view problem
by Venish Khant 31 May '16

31 May '16

Hi all I am using cpan Net::LDAP module to access LDAP entries. I want to search LDAP entries using Net::LDAP search method. When I do search, I want some limited number of entries from search result, for this(searching) process I am using Net::LDAP::Control::VLV module. But I get error on VLV response control. Please, any one have idea about this error. * Error:* Died at vlv.pl line 50, This is my example. I changed the font style of line 50 #!/usr/bin/perl -w use Net::LDAP; use Net::LDAP::Control::VLV; use Net::LDAP::Constant qw( LDAP_CONTROL_VLVRESPONSE ); use Net::LDAP::Control::Sort; sub procentry { my ( $mesg, $entry) = @_; # Return if there is no entry to process if ( !defined($entry) ) { return; } print "dn: " . $entry->dn() . "\n"; @attrs = $entry->attributes(); foreach $attr (@attrs) { #printf("\t%s: %s\n", $attr, $entry->get_value($attr)); $attrvalue = $entry->get_value($attr,asref=>1); #print $attr.":". $entry->get_value($attr)."\n"; foreach $value(@$attrvalue) { print "$attr: $value\n"; } } $mesg->pop_entry; print "\n"; } $ldap = Net::LDAP->new( "localhost" ); # Get the first 20 entries $vlv = Net::LDAP::Control::VLV->new( before => 0, # No entries from before target entry after => 19, # 19 entries after target entry content => 0, # List size unknown offset => 1, # Target entry is the first ); my $sort = Net::LDAP::Control::Sort->new( order => 'cn' ); @args = ( base => "dc=example,dc=co,dc=in", scope => "subtree", filter => "(objectClass=inetOrgPerson)", callback => \&procentry, # Call this sub for each entry control => [ $sort, $vlv ], ); $mesg = $ldap->search( @args ); # Get VLV response control *($resp) = $mesg->control( LDAP_CONTROL_VLVRESPONSE ) or die;* $vlv->response( $resp ); # Set the control to get the last 20 entries $vlv->end; $mesg = $ldap->search( @args ); # Get VLV response control ($resp) = $mesg->control( LDAP_CONTROL_VLVRESPONSE ) or die; $vlv->response( $resp ); # Now get the previous page $vlv->scroll_page( -1 ); $mesg = $ldap->search( @args ); # Get VLV response control ($resp) = $mes # Now page with first entry starting with "B" in the middle $vlv->before(9); # Change page to show 9 before $vlv->after(10); # Change page to show 10 after $vlv->assert("B"); # assert "B" $mesg = $ldap->search( @args );g->control( LDAP_CONTROL_VLVRESPONSE ) or die; $vlv->response( $resp ); -- Venish Khant www.deeproot.co.in

OpenLDAP and dynalogin (two-factor auth with HOTP)
by Daniel Pocock 29 Jun '15

29 Jun '15

Some time ago I created the dynalogin ( http://www.dynalogin.org ) solution for two-factor authentication. I'm just contemplating how to make it easier to integrate, and making it convenient to use with OpenLDAP seems like a good strategy: can anyone comment on that? The initial thoughts that I have about the subject: - SASL based solution (dynalogin has digest capability already, so it could be adapted for SASL PLAIN or DIGEST-MD5) - should not prevent password logins (user should be able to use either password or HOTP code) - should enable people to use it indirectly (e.g. if someone already has pam_ldap working, they should be able to add dynalogin to their OpenLDAP server and get immediate benefit) - use cases: UNIX login, high-security webmail login, VPN and OpenID provider backed by OpenLDAP I know that SASL already supports OTP, but that is not HOTP, it is OPIE (or S/Key) RFC 2289: http://tools.ietf.org/html/rfc2289 whereas HOTP is RFC 4226: http://www.ietf.org/rfc/rfc4226.txt HOTP is considered more secure and more widely implemented.

idassert-authzFrom ignored
by Charles Bueche 22 Aug '14

22 Aug '14

Hi, I have an OpenLDAP proxy using back_meta to talk to two back-ends Microsoft AD servers. My goal is to provide a single view of both AD trees. Basically, it works, as long as I use a bind account which exists in one of the back-end AD's. However, to first search where an AD account is, I would like to use a local account on the LDAP proxy. To my understanding, I need to use database meta suffix dc=proxy,dc=stuff,dc=ch rootdn "cn=root,dc=proxy,dc=stuff,dc=ch" rootpw "secret" subordinate ... idassert-bind bindmethod=simple binddn="CN=srvLDAP,..." credentials="..." mode=none flags=non-prescriptive idassert-authzFrom "dn.exact:cn=root,dc=proxy,dc=stuff,dc=ch" The DN "cn=root,dc=proxy,dc=stuff,dc=ch" does exist in the proxy and can do local searches. However, the account defined in the idassert is never used, and the connections to the back-ends AD's fail. Respectively, I think they are contacted using anonymous instead of the account I specify (not sure about the anonymous part, the debug log isn't very clear about it). Hints welcome. Below is a part of the relevant log if it helps.

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.

syncrepl_del_nonpresent leading to directory implosion

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

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

Re: creating a cn=config modules

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?
