About issues with syncprov configuration

Hey Guys, how are you doing ? Well, I have the follow environment: **Server 1: /etc/openldap/slapd.conf ( Port 389 ) modulepath /usr/local/openldap/lib64/ moduleload back_ldap moduleload translucent moduleload dynlist moduleload back_monitor backend mdb backend ldap allow bind_v2 allow bind_anon_dn database mdb directory /usr/local/openldap/var/openldap-translucent suffix "dc=br" rootdn "ZZZZZZ" rootpw ZZZZZZZ maxsize 4294967296 sizelimit 100000 overlay translucent uri "ldap://localhost:1389/" translucent_bind_local on translucent_pwmod_local on translucent_local XXXXX idassert-bind bindmethod=none overlay dynlist dynlist-attrset groupOfURLs memberURL member:uniqueMember In the port 1389: /etc/openldap/slapd-syncrepl.conf # syncrepl directives syncrepl rid=0 provider=ldap://Production_Server:389 bindmethod=simple binddn="ZZZZZZZZZZZZZZZ" credentials=XXXXXXXXX searchbase="dc=br" logbase="cn=accesslog" logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" type=refreshAndPersist retry="60 +" syncdata=accesslog # Refer updates to the master updateref ldap://Production_Server:389 **Server 2: Same Configuration Now, I need to add a new server, but without a translucent configuration, only a consumer.

search with a wildcard works, with exactly matching string it doesn't
by Gregory House 05 Aug '15

05 Aug '15

Hi If I run a query against my directory with this filter: "(myDeviceId=ZZZ-07430.08.12345678*)" it returns a match showing precisely that myDeviceId = "ZZZ-07430.08.12345678" If I use this filter, without the wildcard and just the actual value "(myDeviceId=ZZZ-07430.08.12345678)" it returns no match. Even if I change the attribute value to something very simple like "x" I still need to include a wildcard in my filter to get any match. This works however: "(myDeviceId:caseExactMatch:=ZZZ-07430.08.12345678)" What gives here? The specific attribute is defined in the schema file as follows: attributetype ( 1.3.6.1.4.1.36200.255.0.17 NAME 'myDeviceId' DESC 'Identifies a device' SUP uid EQUALITY caseExactMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE ) I am no expert, but this makes no sense to me? I feel I am missing something, but what? I am using openldap on CentOS 6 and workign via command-line tools (e.g. ldapsearch). The backend is mdb if that matters. # rpm -qa | grep openldap openldap-clients-2.4.39-8.el6.x86_64 openldap-2.4.39-8.el6.x86_64 openldap-servers-2.4.39-8.el6.x86_64 Thanks for any ideas/suggestions. Best, GH

question on write transaction
by Shu, Xinxin 03 Aug '15

03 Aug '15

Hi list, recently I wrote app on LMDB, found that for every write , lmdb lock a global lock when transaction is created , and release this lock in mdb_txn_commit, on Ubuntu, this lock is implemented by pthread_mutext_t. in my app, I create write transaction in a thread, then commit this write transaction in another thread, since lmdb use pthread_mutex_unlock to release this lock, according to manual , attempting to unlock the mutex if it was not locked by the calling thread results in undefined behavior, then my app cannot create write transaction . So does this issue known to community or is there any way to work around? Cheers, xinxin

I want to use memberof overlay but I do not have a clue on how to even look at it.
by Eliezer Croitoru 01 Aug '15

I want to use memberof overlay but I do not have a clue on how to even look at it. I have tried to use this: http://www.schenkels.nl/2013/03/how-to-setup-openldap-with-memberof-overlay… which kind of worked and it has added something to my database. Now I have tried to run some search but either I am doing something wrong or the memberof is not loaded. So first, how do check that it is loaded? I was thinking about : ldapsearch -x -H ldap:/// -b cn=module but again I am unsure since it won't give results. I am trying to use memberof for squid to match a group membership. Any hints? directions to understand? I understand the basics of LDAP but this is something above basic LDAP. Thanks, Eliezer

Increasing memory usage on successive LMDB reads
by Rohit Girdhar 31 Jul '15

31 Jul '15

Hi I'm using LMDB (original C interface) to store and read some data. However, I notice that my resident memory usage (RES in `htop`) keeps rising with each call to mdb_get with unique keys. It does not change if I do a repeated call to mdb_get with a key I've used before. It looks like mdb_get is caching the reads, but I want to make sure what effect it is really having on my system. Is there some way to limit the amount of memory lmdb can use for this? Or is it something strange and should not be happening? Thanks Rohit

Slapd-meta and multiple uri
by Nicolas RENAULT 31 Jul '15

31 Jul '15

Hello , I have a problem with meta and multiple uri : Two AD server opensuse 13.1 openldap 2.4.39 (install from repo) make a meta backend that work but I when I configure it I use this directive , try to make a failover conf : uri ldap://172.17.150.47:3268/ou=AD,ou=TOUT,dc=example,dc=fr ldap://172.17.150.48:3268/ Work like a charm until 172.17.150.47 go down --> slapd never try to contact 172.17.150.48 ... slapd.conf ( relevant part ) ---------------------------------------------------------- network-timeout 1 timeout 3 idletimeout 10 writetimeout 10 database meta suffix "ou=AD,ou=TOUT,dc=example,dc=fr" uri ldap://172.17.150.47:3268/ou=AD,ou=TOUT,dc=example,dc=fr ldap://172.17.150.48:3268/ suffixmassage "ou=AD,ou=TOUT,dc=example,dc=fr" "dc=example,dc=fr" idassert-bind bindmethod=simple binddn="cn=xxxxxx,cn=Users,dc=example,dc=fr" credentials=<secret> mode=none idassert-authzFrom "dn.regex:.*" -------------------------------------------------------------- I search on the list and found this : http://www.openldap.org/lists/openldap-technical/201208/msg00231.html (one post on the thread, I read all of them) The problem is exactly the same : if I start slapd and 172.17.150.47 not present (iptable output drop or reject) never ask 172.17.150.48 (tcpdump on the interface of slapd server) in http://www.openldap.org/lists/openldap-technical/201208/msg00247.html (same thread) Howard Chu : Sounds like you should file an ITS. Pierangelo: looking at libldap/request.c and libldap/.open.c, it appears that request.c:ldap_new_connection() expects open.c:ldap_int_open_connection() to return -2 on an asynch open, but ldap_int_open_connection() unconditionally returns 0. This is probably interfering with back-meta's urllist_proc. -- -- Howard Chu CTO, Symas Corp.http://www.symas.com Director, Highland Sunhttp://highlandsun.com/hyc/ Chief Architect, OpenLDAPhttp://www.openldap.org/project/ so I look to the ITS 7372 http://www.openldap.org/its/index.cgi/Incoming?id=7372;selectid=7372 But no answers, and no trace on changelog it's something wrong in my conf (if so tell me what) and if no can some of the dev take a look at the problem ? Thank's and have a good day. Nicolas

That's been a mental error, I was thinking of objectclass=user. If your directory is running, what is your problem? I have integrated Hadoop and Jenkins into my directory without any problems.

ldap proxy to AD - UnicodePwd: attribute type undefined

Hello I've installed a openldap as proxy in a DMZ for authentication forwarding to an Active Directoy. The Proxy is used by a VPN gateway. That all works very well, but password change from client fails with following error: slapd[30661]: conn=1001 op=5 do_modify slapd[30661]: conn=1001 op=5 do_modify: dn (cn=XPTEST5,ou=Users,dc=myorg,dc=net) slapd[30661]: >>> dnPrettyNormal: <cn=TEST5,ou=Users,dc=myorg,dc=net> slapd[30661]: <<< dnPrettyNormal: <cn=TEST5,ou=Users,dc=myorg,dc=net>, <cn=xptest5,ou=users,dc=myorg,dc=net> slapd[30661]: conn=1001 op=5 modifications: slapd[30661]: delete: UnicodePwd slapd[30661]: one value, length 26 slapd[30661]: add: UnicodePwd slapd[30661]: one value, length 26 slapd[30661]: conn=1001 op=5 MOD dn="cn=TEST5,ou=Users,dc=myorg,dc=net" slapd[30661]: conn=1001 op=5 MOD attr=UnicodePwd UnicodePwd slapd[30661]: send_ldap_result: conn=1001 op=5 p=3 slapd[30661]: send_ldap_result: err=17 matched="" text="UnicodePwd: attribute type undefined" slapd[30661]: send_ldap_response: msgid=6 tag=103 err=17 slapd[30661]: conn=1001 op=5 RESULT tag=103 err=17 text=UnicodePwd: attribute type undefined slapd[30661]: daemon: activity on 1 descriptor slapd[30661]: daemon: activity on: slapd[30661]: slapd[30661]: daemon: epoll: listen=7 active_threads=0 tvp=zero slapd[30661]: daemon: activity on 1 descriptor slapd[30661]: daemon: activity on: As I understand, UnicodePwd is a proprietary "standard" MS attribute in AD to store the password but the RFC attribute is the userPassword.
