Problem with "force user to password reset at first login
by Rajagopal Rc 30 Oct '23

30 Oct '23

Hi, I am trying to force users to change their password at first login or after password reset by administrator. Tried following: 1)Password policy 'pwdMustChange TRUE' doesn't seems to be working as non of the users get prompt to change their password at first login. 2) used the 'pwdReset TRUE' attribute in users attributes, and it won't prompt to change the password and didn't allow to login i observe below messages in log "slapd[12684]: connection restricted to password changing only slapd[12684]: send_ldap_result: err=50 matched="" text="Operations are restricted to bind/unbind/abandon/StartTLS/modify password" slapd[12684]: conn=1053 op=1 SEARCH RESULT tag=101 err=50 nentries=0 text=Operations are restricted to bind/unbind/abandon/StartTLS/modify password" Please help me configure the option to force all users to change their password at first login or after pwd reset by administrator.

role based authorization -> dynacl module?
by Daniel Tröder 11 Oct '18

11 Oct '18

Hello everyone, I am in the process of implementing a role concept via ACLs and hope for a hint so that I don't invent the wheel a second time. Specifically, it is about identity management for schools. A user (object) can have several roles in multiple schools. Permissions on other LDAP objects can thus differ depending on the role(s) the user and the object have in the same school(s). For example, a user could have been assigned the following roles that are scattered over several schools: → "Teacher" in school 1 → "School admin" in school 2 → "Parent" in school 3 → both "Teacher" and "Staff" in school 4 ACLs should now be defined accordingly, e.g. → the role "teacher" at school X can reset the password for the role "student" at school X → the role "teacher" at school X *cannot* reset the password for the role "student" of school Y → the role "school administrator" at school X can reset the password for the roles "student" and "teacher" at school X → ... So far I have not seen any way to map such a construct via groups or sets without including a separate ACL for each group, which is a performance issue. Is there another way to map the role concept besides implementing an own dynacl module? Greetings, Daniel

duplicated naming context when using syncrepl proxy
by Jochen Keutel 05 Sep '18

05 Sep '18

Hallo, I'm using OpenLDAP on Debian 9 (2.4.44) and started to configure replication: szenario syncrepl proxy (push based replication, see 18.3.5 in OpenLDAP Admin Guide - "primary directory also contains back-ldap databases"). Configuring the LDAP backend leads unfortunately to a root DSE showing the same name context twice: namingContexts: dc=keutel,dc=de namingContexts: dc=keutel,dc=de Is this a known problem? Esp. this stops PHPLDAPAdmin from working: It prints a lot of PHP arrays in this case. I've set "hidden on" for this backend but the problem remains. My configuration: 1. slapd.conf on server1 (master): database ldap hidden on suffix "dc=keutel,dc=de" rootdn "cn=admin,dc=keutel,dc=de" uri ldaps://server2/ lastmod on restrict all acl-bind bindmethod=simple binddn="cn=replication,dc=keutel,dc=de" credentials=secret syncrepl rid=001 provider=ldaps://server1/ binddn="cn=replication,dc=keutel,dc=de" bindmethod=simple credentials=secret searchbase="dc=keutel,dc=de" type=refreshAndPersist retry="5 5 300 5" 2. converting this to dynamic config using slaptest gives the following entry: dn: olcDatabase={2}ldap objectClass: olcDatabaseConfig objectClass: olcLDAPConfig olcDatabase: {2}ldap olcHidden: TRUE olcSuffix: dc=keutel,dc=de ... 3. starting slapd with this dynamic configuration 4. reading rootDSE: attribute namingContexts occurs twice with the same value. How can this be solved? Regards Jochen.

Problem with ACLs
by Bill Bradford 31 Aug '18

31 Aug '18

Trying to give a single user "read only" access to everything in the database including userPassword info. Here's the LDIF file I'm using w/ldapmodify: dn: olcDatabase={2}hdb,cn=config changetype: modify replace: olcAccess olcAccess: {0}to attrs=userPassword,shadowLastChange by dn="cn=Manager,dc=domain,dc=com" write by dn.exact="uid=romanager,ou=Users,dc=domain,dc=com" read by anonymous auth by self write by * none olcAccess: {1}to dn.base="" by * read olcAccess: {2}to * by dn="cn=Manager,dc=domain,dc=com" write by * read However, authenticating as uid=romanager,ou=Users,dc=domain,dc=com lets that user read his own password hash, but nobody else's. In other words it's authenticating just like any other user, and it's as if the by dn.exact="uid=romanager,ou=Users,dc=domain,dc=com" read line is being ignored. The change is being applied as I've looked at the database files for the config. I've tried restarting slapd, etc. Any suggestions? @(#) $OpenLDAP: slapd 2.4.44 (Aug 4 2017 14:23:27) $ Bill -- Bill Bradford Houston, Texas USA

empty reqmod attribute
by David Coutadeur 31 Aug '18

31 Aug '18

Hi, I am experiencing a segfault on an OpenLDAP 2.4.44 instance. The architecture is: - 2 OpenLDAP - multimaster mirrormode - delta-syncrepl The error seems to be in the syncrepl process, in a particular accesslog entry. When I give a look to the entry, I realize that some attributes in reqmod are empty, which seems strange because the value can't be empty in the directory. For example: reqMod: inetUserStatus:= Does anyone know if this behaviour is normal, and what is happening? Thanks in advance. David

Unique overlay confusing
by Ervin Hegedüs 30 Aug '18

30 Aug '18

Hi there, I've followed the docs (and some forums), and made these modifications: (OpenLDAP doc: http://www.openldap.org/doc/admin24/overlays.html#Attribute%20Uniqueness) dn: cn=module,cn=config cn: module objectClass: olcModuleList olcModulePath: /usr/lib/ldap/ olcModuleLoad: unique.la dn: olcOverlay=unique,olcDatabase={1}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcUniqueConfig olcOverlay: unique olcUniqueAttribute: uid olcUniqueAttribute: mail olcUniqueAttribute: uidNumber olcUniqueAttribute: sn olcUniqueAttribute: cn but I still can set the mail attribute as same e-mail address for two different users. I've tried this config too: dn: olcOverlay=unique,olcDatabase={1}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcUniqueConfig olcOverlay: unique olcUniqueUri: ldap:///?uid?sub? olcUniqueUri: ldap:///?mail?sub? olcUniqueUri: ldap:///?uidNumber?sub? olcUniqueUri: ldap:///?sn?sub? olcUniqueUri: ldap:///?cn?sub? What em'I missing? Thanks, a.

Recommended way to transfer data from one cluster to the other?
by Karsten Heymann 29 Aug '18

29 Aug '18

Hi, We're replacing our aging LDAP Cluster (Debian 7, slapd 2.4.40, 2 masters with syncrepl and mirror mode, 2 slaves) with a new cluster of the same layout (2.4.44, probably 2.4.46, on Debian 9). I now wonder what the best way is to transfer the data from the old to the new cluster. As far as I can see, we have three options to transfer the data: 1) ldapsearch + ldapadd 2) slapcat + slapadd 3) Configure a temporary syncrepl rule on the new masters to fetch the data from the old ones. Which one is the preferred one? I would assume slapcat and slapadd, but I must admit I have not fully understood the purpose of the -S and -w switch. Should we somehow filter the *CSN-fields from the exported ldif as I assume they make no sense for the new cluster or are they automatically fixed when using slapadd with said options? I'm sorry if this topic has been discussed here before but my (probably lacking) google skills did not return anything obvious. Best regards Karsten
