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

Fwd: ppolicy and logging
by Maurice Barlow 11 Oct '18

11 Oct '18

Greetings, using 2.4.45 on Solaris 11 ( shipped with the distro ) with ppolicy. Working on the locking out of the accounts and want to configure detailed messages pumped into syslog to track lockout activity. At the moment what i see is only "errorno=49". Any ideas or a secure log_level ? cheers MB

Using ppolicy and autogroup to apply policy to a group a users
by Clément OUDOT 08 Oct '18

08 Oct '18

Hello, we often have the question on this list: how apply a policy to a branch or a group of users? I was thinking we could use autogroup we this kind of configuration: dn: olcOverlay={9}autogroup,olcDatabase={1}mdb,cn=config objectClass: top objectClass: olcConfig objectClass: olcAutomaticGroups objectClass: olcOverlayConfig olcOverlay: {9}autogroup olcAGattrSet: pwdPolicy memberUrl seeAlso olcAGmemberOfAd: pwdPolicySubentry The goal is to have a memberUrl inside a pwdPolicy object, that can target accounts that need to have this policy. For example: dn: cn=default,ou=ppolicies,dc=example,dc=com changetype: modify replace: memberURL memberURL: ldap:///ou=users,dc=example,dc=com??one?(uid=user*) The autogroup "olcAGattrSet" is working well, I can see the seeAlso values. But the "olcAGmemberOfAd" does not seem to be applied. I don't know if this is a conflict with ppolicy overlay, or other overlays (dynlist, memberof). I join a full debug log, maybe you can find what is going wrong. We see that "autogroup_member_search_modify_cb" function is called, but user entry is not modified. Do you think this configuration could work? -- Clément Oudot | Identity Solutions Manager clement.oudot(a)worteks.com Worteks | https://www.worteks.com

This is expected to be the only testing call for 2.4.47, with an anticipated release, depending on feedback, during the week of 2018/10/15. Generally, get the code for RE24: <http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=snapshot;h=refs/h…> Configure & build. Execute the test suite (via make test) after it is built. Optionally, cd tests && make its to run through the regression suite. Thanks!

Making contextCSN, entryCSN visible only to sync user?
by Karsten Heymann 03 Oct '18

03 Oct '18

Hi, I wonder if it would be harmful to modify our slapd acls so that only the user used for syncrepl replication can view the contextCSN/entryCSN attributes on the master servers. We're considering this to prevent unintended partial replication (for example without password fields) in case there is a misconfiguration and the slave comes as another user/anomymous. Ideally I would block anonymous access to our database completely but we have to update a lot of services until this can be achieved. Does this idea make sense or am I missing something? Best regards Karsten

Q: Renewing certificates online
by Ulrich Windl 03 Oct '18

03 Oct '18

Hi! I have a question: I updated the contents of certificate and key file (same location and file name) while slapd was running. Is it expected that slapd will recognize (and use) the new certificates, or is a restart or reload needed? Out certificates will expire soon... Regards, Ulrich

Hello Quanah, Thanks for clarification. > > That confuses me a little bit. > > All replication on openLDAP are based on syncreplication (slurpd is > > vanished a long time ago) > > So what kind of replication means the manual page (-> "Replica servers")? > > It means that you run it in a replicated environment at your own risk. > Unfortunately, there is no defined standard for the "memberOf" > functionality (it's a MS hack) and so there's nothing that details how it > should or shouldn't behave with replication. In general, things work fine > as long as: > > a) The server(s) never go into REFRESH > and > b) You never bring up a new replica with an empty database (which then does > a full REFRESH) That means, if I run in mirrormode, I can turn on the memberOf overlay on the active openLDAP server and off on the slave. Then REFESH ist supported?! In emegency case (hardware error) I can make the mirror (manual) aktive an turn the overlay on?! Thanks Meike
