Hello, I wonder, why do I get a Segmentation fault when I use mdb_put with MDB_RESERVE on a key that already exists ? -- Best regards, Simon Majou

ClearText Passwords in slapcat: please provide some inputs
by Manuel Afonso 21 Aug '15

21 Aug '15

Hi people, I am using ubuntu and phpldapadmin to manage openldap. I have here a big issue: when using phpldapadmin/openldap, all the times there is (for each user/entry) a field with cleartextPassword: <cleartextpassword> (this is seen in slapcat output) What I want is to put in place a mechanism where there is no plain text field with the password in clear in each entry of openldap. I have read about ppolicy overlay, slappasswd and so on but so far I was not able to figure out how to avoid this annoying clear text password available when I do a slapcat (as root of course) Does anybody had such an issue ? Any ideas or links to point for a solution? Another question: is it possible that this clear text password is somehow needed for the correct operation of openldap? Thanks a lot for your time and (I hope) help. Kind regards, Manuel - Lisbon PT This is what I got for the user mafonso (me) when doing a slapcat > output : (as can be seen there is the field cleartextPassword: with pass in clear text) dn: cn=mafonso,ou=***,dc=***,dc=***,dc=***,dc=pt objectClass: ****Person objectClass: mailAccount objectClass: sambaSamAccount objectClass: posixAccount objectClass: top givenName: Manuel sn: Afonso displayName: Manuel Afonso cn: mafonso mailacceptinguser: 1 maildrop: mafonso(a)***.pt intranetRole: cn=**,ou=**,ou=**,dc=**,dc=**,dc=**,dc=pt ... portalRole: *** ... gidNumber: 516 sambaSID: *** uidNumber: 1399 uid: mafonso homeDirectory: /home/mafonso intranetStatus: U sambaAcctFlags: [UX] loginShell: /bin/false mailacceptinggeneralid: mafonso@**** mailacceptinggeneralid: ***(a)**.**.**.pt userPassword:: e1N.... cleartextPassword: <cleartextpassword> sambaNTPassword: D6... sambaLMPassword: 45...

Re: Slapd is coming down

Hello quanah! Yes, I know, my SO killed the slapd because it was configured. But I don't have any other service in the server, only the openldap. Quanah, below follow the information: - Openldap-syncrepl: 2 GB - Openldap-translucent: 567 MB Now, about the slapd process. The strange is the size in the memory: - Server 1 Tasks: 110 total, 1 running, 109 sleeping, 0 stopped, 0 zombie Cpu(s): 0.3%us, 0.3%sy, 0.0%ni, 99.2%id, 0.2%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 12248128k total, 5686580k used, 6561548k free, 223244k buffers Swap: 2097148k total, 88940k used, 2008208k free, 4488408k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4965 ldap 20 0 4692m 777m 527m S 1.0 6.5 101:16.12 slapd 1460 ldap 20 0 9700m 2.1g 1.9g S 0.3 18.0 1174:58 slapd ldap 1460 1 2 Jul12 ? 19:34:58 /usr/local/openldap/libexec/slapd -h ldap://127.0.0.1:1389 ldaps:// 127.0.0.1:1636 -f /usr/local/openldap/etc/openldap/slapd-syncrepl.conf -u ldap -g ldap -l local3 ldap 4965 1 10 Aug19 ? 01:41:19 /usr/local/openldap/libexec/slapd -h ldap://*:389 ldaps://*:636 -f /usr/local/openldap/etc/openldap/slapd.conf -u ldap -g ldap -l local4 root 14399 14157 0 09:12 pts/0 00:00:00 grep ldap - Server 2 Tasks: 113 total, 1 running, 112 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.2%sy, 0.0%ni, 99.7%id, 0.2%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 12194476k total, 8111400k used, 4083076k free, 213632k buffers Swap: 2097148k total, 7344k used, 2089804k free, 7225108k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 30907 ldap 20 0 8832m 2.3g 2.2g S 0.0 19.9 11:10.55 slapd 30956 ldap 20 0 4486m 502m 339m S 0.0 4.2 7:34.95 slapd ldap 30907 1 1 Aug19 ? 00:11:10 /usr/local/openldap/libexec/slapd -h ldap://127.0.0.1:1389 ldaps:// 127.0.0.1:1636 -f /usr/local/openldap/etc/openldap/slapd-syncrepl.conf -u ldap -g ldap -l local3 ldap 30956 1 0 Aug19 ? 00:07:39 /usr/local/openldap/libexec/slapd -h ldap://*:389 ldaps://*:636 -f /usr/local/openldap/etc/openldap/slapd.conf -u ldap -g ldap -l local4 Otherwise, in the few days, the slapd process increase the consumption until remain nothing!

ACL rule: getting crazy with it.
by Simone Taliercio 20 Aug '15

20 Aug '15

Hi All, I've Jasig CAS connected to OpenLDAP for users authentication. My LDAP Schema is the following: dc=com dc=companyA,dc=com ou=user,dc=companyA,dc=com dc=companyB,dc=com ou=user,dc=companyB,dc=com I would like to give to a specific user (cn=admin,ou=user,dc=companyB,dc=com) the ability to create inetOrgPerson objetcs under ou=user,dc=companyA,dc=com and the restriction to have only search access to ou=user,dc=companyB,dc=com where actually some attributes should be hidden (such as userPassword). I tried several ACL but always with one strange problem: a user is able to login via CAS. Then, he/she logouts and if try with a different account then LDAP returns DN_RESOLUTION_FAILURE. That issue is occurring even with a simple ACL such as: access to * by self write by anonymous auth by users search The only way to workaround that issue is removing any ACL or leaving "by users read". As DN bind I'm using dc=com. Any suggestion? I cannot understand if focusing on CAS for this issue, or ACL LDAP side. Thanks a LOT for the support! Simone

Hello Guys, how are you doing ? In the last weeks, my openldaps servers were suffering with many come down. I have a peak about the 400 connections per peer ( We have 2 ldap servers ).

0.9.16 build problems for android
by Kristoffer Sjögren 19 Aug '15

19 Aug '15

Hi This is a long shot. Just upgraded LMDB to 0.9.16 for lmdbjni (Java bindings for LMDB) and when building for android-ndk-r10e I get a build error complaing about undeclared PTHREAD_MUTEX_ROBUST [1]. The build procedure uses automake and is quite complex because of Java JNI bindings but maybe the build error/output rings a bell anyway? The build works fine with LMDB 0.9.15. Cheers, -Kristoffer [1] src/mdb.c:4636:49: error: 'PTHREAD_MUTEX_ROBUST' undeclared (first use in this function) [2] Full build output - http://pastebin.com/JwreP0dZ [3] agcc #!/bin/bash $NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc --sysroot=$NDK/platforms/android-19/arch-arm -DMDB_DSYNC=O_SYNC $@

Upgrading OpenLDAP from 2.4.39 to 2.4.41
by Brian Wright 18 Aug '15

18 Aug '15

We have a 2-way master production cluster actively running 2.4.39. We are wanting to upgrade to 2.4.41 (we haven't yet internally certified 42). What is the best practices around upgrading this cluster while keeping at least one of the servers online? Is it replication-safe to have one node on 2.4.39 and one on 2.4.41 for a short period? If not, I can temporarily comment out the syncrepl statements until both servers are on 2.4.41 and then reenable replication after both are upgraded. We can live with short inconsistency period between the servers during the upgrade of the servers until we can resume replication. Also, is the DB format fully compatible between these two versions or would it be better to reload the DB new from an LDIF backup on 2.4.41? Is there an upgrade doc somewhere that discusses these issues? Thanks. -- Signature *Brian Wright* *Sr. UNIX Systems Engineer * 901 Mariners Island Blvd Suite 200 San Mateo, CA 94404 USA *Email *brianw(a)marketo.com <mailto:brianw@marketo.com> *Phone *+1.650.539.3530** *****www.marketo.com <http://www.marketo.com/>* Marketo Logo

OpenLDAP proxy referral via SSL
by Declan O'Doherty 18 Aug '15

18 Aug '15

I am trying to set up an OpenLDAP server (2.40) on CentOS 6 that uses a proxy referral to another LDAP server (OpenDJ) , all via SSL/TLS The referral works if I do not use SSL but when I configure slapd.conf to require certs, I get an invalid password error: res_errno: 49, res_error: <Invalid password.>, res_matched: <> The proxy is configured to use SASL EXTERNAL binding but when connecting to the OpenDJ service, it binds anonymously: ldap_back_dobind_int: DN="<certificate DN>" without creds, binding anonymouslyldap_sasl_bind The same configuration works on Windows using OpenLDAP 2.38 Here is the configuration for the ldap backend in slapd.conf: database ldap suffix "ou=organization unit, o=organization" uri "ldaps://test.ldap.com:636/" chase-referrals yes idassert-bind bindmethod=sasl saslmech=EXTERNAL binddn="O=ORG,OU=ORGUNIT,C=US" tls_cacert="/path/to/ca cert.pem" tls_cert="/path/to/server cert.pem" tls_key="/path/to/server key.pem" tls_reqcert=demand mode=self Thank you
