Hi, I want to configure SASL in my OpenLDAP server. I saw in documentation that I have to set 'sasl-host' and 'sasl-realm' in slapd.conf In fact I don't use slapd.conf but the cn=config architecture. So where put the parameters ? Thanks for any help

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. For others in discussion ________________________________ De: Mauricio Tavares <raubvogel(a)gmail.com> Para: rodrigo tavares <rodrigofariat(a)yahoo.com.br> Enviadas: Quarta-feira, 31 de Outubro de 2012 14:14 Assunto: Re: Error : when create usermachine in LDAP A few questions (I am replying directly to you instead of to the list): 1) How comfortable are you with linux/unix in general and debian specifically?

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

If not, it could be my fault in the configuration. Maybe someone had a similar problem and could share his experience. By not being able to provide useful configuration snippets, I *have not* asked for a specific help. With your answers, do I have to assume that with OL2.4.x you never faced a problem syncrepl-ing a tree composed by multiple db's, testing both scenarios (more or less) similar to the two I presented from a (very) high-level-view perspective?

memberOf data in new replica servers 2.4.31
by Todd Stein 02 Nov '12

02 Nov '12

Hi, I have a provider server and five consumer servers, all of which have the memberOf overlay configured: overlay memberof memberof-group-oc groupOfUniqueNames memberof-member-ad uniqueMember memberof-refint true memberof-dangling ignore syncrepl rid=005 provider=ldap://<server>:389 type=refreshAndPersist interval=00:00:05:00 retry="60 10 600 +" searchbase="dc=<removed>,dc=<removed>" filter="(objectClass=*)" scope=sub attrs="*" schemachecking=off starttls=no bindmethod=simple binddn="cn=replica,dc=<removed>,dc=<removed>" credentials=<removed> When I bring a new replica online, it appears that entries are replicated in the order that they were created on the provider server which produces many "memberof_value_modify failed err=32" messages in the log, and incomplete memberOf data. To get around this, I wrote a script which empties all groups prior to replication, and then recreates the memberships after the initial replication. This seems to work, but is hardly ideal. Is there a "more correct" way of replicating memberOf values without manipulating my provider each time I bring up a new consumer? Thank you very much, Todd
