his is the first testing call for OpenLDAP 2.5.18. Depending on the results, this may be the only testing call. Generally, get the code for RE25: <https://git.openldap.org/openldap/openldap/-/archive/OPENLDAP_REL_ENG_2_5/o…> Extract, configure, and build. Execute the test suite (via make test) after it is built. Optionally, cd tests && make its to run through the regression suite. Thanks!

Hi, I want used slapo-rwm to redirect a rule in a different URI. Here my configuration : /database meta suffix "dc=lan" uri "ldaps://server1/dc=lan" / /rewriteEngine on rewriteContext default rewriteRule ".*" ".*" ":" rewriteMap ldap attr2dn "ldap://server2/dc=lan?dn?sub" rewriteContext bindDN rewriteRule ".*" "${attr2dn($0)}" ":@I"/ I d'ont really understand rewrite map.

Permissive Modify and mdb
by lesignor＠cirad.fr 02 Apr '24

02 Apr '24

Hi, I try to modify an entry with permissive modify control. The response is protocole error : permissiveModify control value not absent. I check with wireshark the request, and there was no value with the control, but the control was marked as critical. The problem appears with openldap 2.5.x and 2.6.x with mdb database. It is ok with openldap 2.4.x with bdb database. So is the permissive modify control supported with mdb database in openldap >= 2.5.x ? Thank for your help

kerberos-cache location
by Stefan Kania 02 Apr '24

02 Apr '24

I normally use Debian for OpenLDAP and Kerberos, but now I have to uses Alamalinux 9. When I create a Ticket with kinit I'm getting: --------- u1-prod@ldapserver1 ~]$ kinit Password for u1-prod(a)EXAMPLE.NET: [u1-prod@ldapserver1 ~]$ klist Ticket cache: KCM:10001 Default principal: u1-prod(a)EXAMPLE.NET --------- So the ticket cache is the KCM-daemon and not FILE: like in Debian. When I die an ldapsearch or an ldapwhoami I'm getting ----------- [u1-prod@ldapserver1 ~]$ ldapwhoami SASL/GSSAPI authentication started ldap_sasl_interactive_bind: Local error (-2) additional info: SASL(-1): generic failure: GSSAPI Error: Miscellaneous failure (see text) (get-principal lstat(/tmp/krb5cc_10001)) ----------- All the ldap-commands are looking for the credential cache in FILE: and not in KCM: I'm using OpenLDAP 2.6 from the repositories. Is there a way that the ldap-commands are using KCM:?

Strange search result in logs

Is there any param that can be in the request to cause the err=4 ? Maybe I should rise the logLevel to find the difference between the two requests ?

how to migrate an openldap server to a new linux server
by xpzhang1971＠gmail.com 26 Mar '24

26 Mar '24

I have an openldap server I want to clone it to another linux server. However, I can't access it by login but can just run ldapsearch because this source openldap server only open port 389. Now I installed openldap-servers package to target linux server, then what? I appreciate if anybody can instruct me or direct me to useful documents.

etensibleObject vs. creating a new schema
by Uwe Sauter 26 Mar '24

26 Mar '24

Hi all, I was wondering if there is any best practice when to use extensibleObject in contrast to creating new objectClasses within a local schema. E.g. I have the need to filter the visibility of posixGroups depending on some attribute when sssd is accessing the directory. What I could do is to use an extra objectClass: extensibleObject to allow all defined attributes (e.g. host) to be used within my object. I could also create a new objectClass ( 2.25.$UUID.1.2.1 NAME 'myGroup' DESC 'Group with host attribute' SUP posixGroup AUXILIARY MAY host ) As far as I can tell using extensibleObject has the disadvantage to more or less disable the checks for correct attribute usage. Are there more positive or negative aspects to extensibleObject? I'd like to hear your thought on this. Thanks, Uwe

Logo usage
by Gloria Semme 21 Mar '24

21 Mar '24

Dear OpenLDAP Technical Team, I am reaching out to seek your guidance and permission regarding the use of the OpenLDAP logo. My team is in the process of creating a Grafana integration designed to facilitate the monitoring of OpenLDAP applications for our users. To enhance user experience and direct attention effectively, we plan to incorporate the OpenLDAP logo within the Grafana Cloud interface. Upon reviewing the available licensing information, we noted the absence of specific guidelines related to the use of the OpenLDAP logo. Given this, we wish to ensure our use aligns with your expectations and policies. Our design considerations include adjusting the logo to fit a square format to suit the dashboard's aesthetic. We are committed to respecting your branding guidelines and are open to any alternative suggestions or requirements you may have. We appreciate your support in this endeavor and look forward to your guidance. Thank you for your guidance. Best regards, -- [image: photo] *Gloria Semme* Sr. Engineering Manager Cloud Infrastructure Observability gloria.semme(a)grafana.com www.grafana.com

olcDbURI
by Bradley T Gill 15 Mar '24

15 Mar '24

Good Morning Group. I am struggling to find any documentation on this. Is there a limit to the amount of olcDbURI that can be defined for SASL? While I'm here, I might as well ask if there is a way to make it more resilient? Our servers get quarantined during pathing of AD and eventually SASL is broken until I restart OpenLDAP. Thanks! Bradley Gill
