Multiple memberOf overlays
by John C. Pfeifer 06 Aug '25

06 Aug '25

I am in the process of converting an existing LDAP infrastructure to OpenLDAP. I have a case where it would be convenient for two different objectClasses to map into the memberOf attribute. Is it possible to define two overlay configs or will they end up fighting each other over the memberOf attribute? For instance: dn: olcOverlay={5}memberofA,olcDatabase={2}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcMemberOf olcOverlay: {5}memberofA olcMemberOfDangling: error olcMemberOfRefInt: FALSE olcMemberOfGroupOC: objectClassA olcMemberOfMemberAD: member olcMemberOfMemberOfAD: memberOf dn: olcOverlay={6}memberofB,olcDatabase={2}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcMemberOf olcOverlay: {6}memberofB olcMemberOfDangling: error olcMemberOfRefInt: FALSE olcMemberOfGroupOC: objectClassB olcMemberOfMemberAD: member olcMemberOfMemberOfAD: memberOf // John Pfeifer Division of Information Technology University of Maryland, College Park

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.

Q: UNKNOWN attributeDescription "AUDITCONTEXT" inserted.
by Ulrich Windl 23 Jul '20

23 Jul '20

Hi! After systemd tearing down one of our LDAP servers I noticed the following message when the server was restarted: slapd[10525]: UNKNOWN attributeDescription "AUDITCONTEXT" inserted. The next line logged was: slapd[10525]: olcServerID: value #1: SID=0x002 (listener=ldap://...:389) (the server is that of SLES12 SP4, 2.4.41 from opensuse-buildservice) The server is one of three MM servers that all have the same configuration and the same version. The schema knows in olcAttributeTypes (olcSchemaConfig): ( 1.3.6.1.4.1.4203.666.11.5.1.30 NAME 'auditContext' DESC 'DN of auditContainer' SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 SINGLE-VALUE NO-USER-MODIFICATION USAGE dSAOperation ) What I'l like to know: Is there any thing I could fix in the configuration to make the message go away, or is it some software issue in slapd? Regards, Ulrich

pwdChangedTime not defined when creating new entry
by Manuela Mandache 06 Jun '20

06 Jun '20

Hello all, We have a directory running on OpenLDAP 2.4.44 with the ppolicy overlay on the main database. When a new entry with a userPassword defined is created, pwdChangedTime is not defined, so this initial userPassword never expires. The directory has been migrated from its OpenLDAP 2.3.34 instance (yes, we missed some steps...), and there the pwdChangedTime is set, and naturally equal to createTimestamp. The overlay is configured as follows: dn: olcOverlay={2}ppolicy,olcDatabase={2}mdb,cn=config objectClass: olcOverlayConfig objectClass: olcPPolicyConfig olcOverlay: {2}ppolicy olcPPolicyDefault: ou=ppolicy,dc=example,dc=com olcPPolicyHashCleartext: TRUE olcPPolicyUseLockout: TRUE Is there a parameter I missed which would switch on setting pwdChangedTime at entry creation? Do I have to provide some other configuration elements? Or is it unreasonable to expect this initialisation of the attribute this way, and only a password change can set it? I think the setting at creation is rather handy... Using pwdMustChange would be difficult, we have a lot of client apps which would be forced to check and probably adapt their authentication procedures. Thank you and regards, Manuela Sent with [ProtonMail](https://protonmail.com) Secure Email.

AD proxy / CAPITAL letters in attributes
by Kevin Olbrich 01 Apr '20

01 Apr '20

Hi! How can I disable the behavior of CAPITAL letters when OpenLDAP proxies an AD? I know they should be case insensitive but I had to debug Rocketchat for two hours to find, they use sAMAccountName (case sensitive) and the app crashed because mine was named SAMACCOUNTNAME. (I will open a bug there but I bet there is a lot of broken SW). Kind regards Kevin

NetworkRadius CentOS pkg uses openldap-ltb which conflict with symas-openldap
by Dave Macias 27 Mar '20

27 Mar '20

Good day Everyone, Back Story: We wanted to install the latest release of Freeradius from NetworkRadius and got a conflict. See post: http://lists.freeradius.org/pipermail/freeradius-users/2020-March/097718.ht… Their response was of course, figure it out and fix it yourself, which I have no problem with. I personally never compiled a rpm file before but i think i have an idea of what needs to be adjusted on their specs file. Wanted to run my changes by you guys, if you could please kindly review.... https://github.com/davama/freeradius-server/commit/7fa0f49e25de874bb5034584… https://github.com/davama/freeradius-server/commit/dab208186d440196c297821f… Not too sure if "BuildRequires" uses the same syntax but "Requires" does, at least what it says here: https://rpm.org/user_doc/boolean_dependencies.html Hope it's clear. Please let me know, if you need any info from me. Any input is much appreciated! Thank you, Dave

OpenLDAP-Proxy in front of AD - Non-DN bind
by Kevin Olbrich 27 Mar '20

27 Mar '20

Hi! I'm new to OpenLDAP / Slapd and try to integrate it into our AD setup. I followed this howto: https://wiki.samba.org/index.php/OpenLDAP_as_proxy_to_AD ... and ended up with this config: https://bitbucket.org/code-orange/django-cdstack-tpl-openldap-proxy/src/mas… Proxy mode works fine, I can bind with DN and password. So far so good. TLS works perfectly. On AD, I can bind using either domain\username or username(a)example.com. Can I enable this again for my proxy? Atm this does not work: Invalid DN-Syntax, invalid DN. I try to provide a secure way to connect a remove machine to our AD to read the contacts (a pbx). Using the DN worked for some devices but some have issues because of the length. If the DN is several OUs deep, the string is to long. Thats why I would like to allow the sAMAccountName as username (or USN, etc.). How can I solve this? Do I need SASL for this? Thank you very much! Kind regards Kevin

logging through systemd-journald is bottleneck
by Markus.Storm＠t-systems.com 21 Mar '20

21 Mar '20

Dear all, we're currently testing performance of OpenLDAP on Oracle/RedHat Linux and quite unexpected actually hit systemd-journald to be a bottleneck. While OpenLDAP happily makes use of all available CPUs, that one is single threaded, braking everything. The only way around I have found is to set olcLoglevel to 0, speeding up my test run by a factor of 6(!). That now of course is not an option to use in production. I'd happily directly write to a file as I did in the old days but I cannot get olcLogfile to work. And even if I was able to get there, how do I stop OpenLDAP from logging to syslogd (which is inevitably forwarding everything to system-journald ....) ? Can anyone give advice how to handle this ? Any hint appreciated (short of "get a decent OS" - that is not an option). Thanks, Markus
