Multiple memberOf overlays
by John C. Pfeifer 05 Aug '25

05 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 22 Jul '20

22 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

openSUSE/SLE builds (was: OpenLDAP 2.4.49 available, LMDB 0.9.25 available)

So you have to know what you're doing! Also I maintain builds installing in separate prefix /opt/openldap-ms and with reduced feature set (e.g. no back-bdb and no back-hdb): https://build.opensuse.org/package/show/home:stroeder:openldap/openldap-ms Please test. Feedback welcome! BTW: In OBS you can also simply branch the above packages to your own OBS home project and adjust the .spec to your own needs. Ciao, Michael.
