Nssov overlay in Ubuntu 12.04
by Simone Scremin 11 Nov '12

11 Nov '12

Hi all, I'm trying to setup the nssov overlay in Ubuntu 12.04. I setup the server as the official doc suggested here: https://help.ubuntu.com/12.04/serverguide/openldap-server.html Now I'm stuck because I didn't find anywhere a working ldif example to enable the addon. I tried with the following ldif: dn: olcOverlay={0}nssov,olcDatabase={1}hdb,cn=config objectClass: olcOverlayConfig objectClass: olcNssOvConfig olcOverlay: {0}nssov olcNssSsd: test ldap:///ou=People,dc=example,dc=com but I get: ldap_add: Invalid syntax (21) additional info: objectClass: value #1 invalid per syntax Can someone please give some advice? Thank you! Simone Scremin

Lastlogon attribute
by jeevan kc 09 Nov '12

09 Nov '12

Hello there Does any versions of openldap schema support the last logon attribute? I am asked to add that attribute to run a report through a application? I don't know if simply addding that attribute on the local schema configuration(openldap 2.4.30) would do it.Is it possible? Thanks John

Replication account kept being deleted
by sgao＠frontier.com 08 Nov '12

08 Nov '12

Hi, I am running into a problem with replication accounts being deleted from directory from time to time. Here is my setup: 1. Master-master replication configuration: On ldap1 Syncrepl rid=002 provider=ldaps://ldap2.example.com interval=00:00:02:00 retry="60 5 300 5" type=refreshAndPersist searchbase="dc=example,dc=com" schemachecking=off bindmethod=simple binddn="cn=repl1,dc=example,dc=com" credentials=password On ldap2 Syncrepl rid=001 provider=ldaps://ldap1.example.com interval=00:00:01:00 retry="60 5 300 5" type=refreshAndPersist searchbase="dc=example,dc=com" schemachecking=off bindmethod=simple binddn="cn=repl2,dc=example,dc=com" credentials=password The DNs "cn=repl1,dc=example,dc=com" and "cn=repl2,dc=example,dc=com" are kept being removed from directory on ldap1 or ldap2. When the DNs exist, replication worked fine. However, once the DNs got removed, replication would stop working upon restarting slapd. The version of OpenLDAP is 2.4.23. Any help would be very much appreciated. Simon

local password change in read-only replica?
by Marc Patermann 06 Nov '12

06 Nov '12

Hi, from a central master/provider server we replicate to (a lot of) sync-repl slave/consumers. Which are then - of course - read-only. We have passwordpolicy turned on on all the servers. Now we have three accounts - each an another "home" replica - which have a newer modifyTimestamp value on their replica then on the master and all other slaves. The userPassword attribute is different on the "home" replica. What could have caused this? In the log I cannot find any changing operation on the replica according to the time in modifyTimestamp.

Re: Error : when create usermachine in LDAP

Hello Mauricio, 1) How comfortable are you with linux/unix in general and debian specifically? Do not take this as an insult; I just want to know what I need to ask. Remember I have no access to your machine. ;) I like much Debian Linux, it's very fast. I began work with Linux, i used Conetiva 6.0 and Red Hat Enteprise/Fedora both using format RPM. Debian have a lot packages. And is free, diffent red hat. 2) Are you using ldap to login to this machine or just to check mail? Well I have a server email with LDAP and Suport Samba. So the base ldap the mailserver is replicated from server samba. Then, all modifications LDAP made go to server samba. It run about 5 minutes. I create users emails e samba users. Making intgretion with users samba. 3) I do speak portuguese (I lived in SJC and then Rio). Would you prefer that a gente fale em portugues? Once again, it is all about your comfort level. Speak an English.

general protection fault when deleting members from a large group (mdb)
by Mundry, Marvin 03 Nov '12

03 Nov '12

Hi, i was trying to remove all members from a group initially having 48428 members one by one. i.e.: dn: cn=students,ou=groups,dc=university,dc=com changetype: modify delete: member member: cn=user1,ou=users,dc=uni-hamburg,dc=de dn: cn=students,ou=groups,dc=university,dc=com changetype: modify delete: member member: cn=user2,ou=users,dc=uni-hamburg,dc=de [...] after some time ldapmodify stops as the slapd stops running. In the syslog i see the following message: Nov 3 15:05:45 oscar slapd[11040]: conn=1000 op=133 MOD dn="cn=students,ou=groups,dc=university,dc=com" Nov 3 15:05:45 oscar slapd[11040]: conn=1000 op=133 MOD attr=member Nov 3 15:05:45 oscar slapd[11040]: conn=1000 op=134 MOD dn="cn=students,ou=groups,dc=university,dc=com" Nov 3 15:05:45 oscar slapd[11040]: conn=1000 op=134 MOD attr=member Nov 3 15:05:45 oscar slapd[11040]: conn=1000 op=133 RESULT tag=103 err=0 text= Nov 3 15:05:45 oscar kernel: [21207.720483] slapd[11045] general protection ip:7fae665cbc1f sp:7faded9c9fc0 error:0 in back_mdb-2.4.so.2.8.5[7fae665a5000+30000] am i doing something wrong or is there a bug in my slapd? i am running openldap-2.4.33 on ubuntu 12.10, compiled with: --enable-dynamic=yes --enable-syslog=yes --enable-slapd=yes --enable-dynacl=yes --enable-crypt=yes --enable-modules=yes --enable-rewrite=yes --enable-bdb=mod --enable-hdb=mod --enable-ldap=mod --enable-mdb=mod --enable-meta=mod --enable-monitor=mod --enable-overlays=mod --with-tls=openssl Best regards, Marvin Mundry
