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.

Re: OpenSSL1.1.1 support after its EOL

Hi Team, Can you please help to address below queries ASAP from OpenLDAP point of view: 1. Please do let us know if OpenLDAP can provide extended support of OpenSSL1.1.1 beyond the EOL(End of life cycle) i.e after september 2023? 2. Does OpenLDAP depend on RHEL for OpenSSL support or Does it package OpenSSL on its own? If it depends on RHEL and RHEL introduces OpenSSL3.0 support, how would this be handled by OpenLDAP?

dynlist vs memberof performance issues
by Mark Cairney 11 Jan '23

Hi, I've been out the LDAP loop for a bit but the recent discussion of the memberof overlay on 2.5 piqued my curiosity. Having upgraded a Dev box, removed the memberof elements from the database and replaced the memberof overlay with dynlist the queries appear to work as expected but are both a) slow and b) heavily CPU-intensive on the LDAP server. 2021-09-01T12:47:17.603513+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 fd=12 ACCEPT from IP=192.168.152.33:58738 (IP=129.215.17.9:636) 2021-09-01T12:47:17.687488+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 fd=12 TLS established tls_ssf=256 ssf=256 tls_proto=TLSv1.3 tls_cipher=TLS_AES_256_GCM_SHA384 2021-09-01T12:47:17.688032+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=0 SRCH base="" scope=0 deref=0 filter="(objectClass=*)" 2021-09-01T12:47:17.688470+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=0 SRCH attr=supportedSASLMechanisms 2021-09-01T12:47:17.688878+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=0 SEARCH RESULT tag=101 err=0 qtime=0.000014 etime=0.000214 nentries=1 text= 2021-09-01T12:47:17.811279+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=1 BIND dn="" method=163 2021-09-01T12:47:17.819249+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=1 RESULT tag=97 err=14 qtime=0.000030 etime=0.009084 text=SASL(0): successful result: 2021-09-01T12:47:17.908889+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=2 BIND dn="" method=163 2021-09-01T12:47:17.909836+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=2 RESULT tag=97 err=14 qtime=0.000031 etime=0.000181 text=SASL(0): successful result: 2021-09-01T12:47:17.938839+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=3 BIND dn="" method=163 2021-09-01T12:47:17.939621+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=3 BIND authcid="mcairney(a)EASE.ED.AC.UK" authzid="mcairney(a)EASE.ED.AC.UK" 2021-09-01T12:47:17.940213+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=3 BIND dn="uid=mcairney,ou=people,ou=central,dc=authorise-dev,dc=ed,dc=ac,dc=uk" mech=GSSAPI bind_ssf=256 ssf=256 2021-09-01T12:47:17.940616+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=3 RESULT tag=97 err=0 qtime=0.000024 etime=0.000409 text= 2021-09-01T12:47:18.227342+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=4 SRCH base="dc=authorise-dev,dc=ed,dc=ac,dc=uk" scope=2 deref=0 filter="(uid=mcairney)" 2021-09-01T12:47:18.227703+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=4 SRCH attr=* + 2021-09-01T12:47:31.392255+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=5 UNBIND 2021-09-01T12:47:31.460705+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 op=4 SEARCH RESULT tag=101 err=0 qtime=0.000031 etime=13.233679 nentries=1 text= 2021-09-01T12:47:31.461098+01:00 bonsai.authorise-dev.is.ed.ac.uk slapd[30075]: conn=1019 fd=12 closed I'm guessing that as the values are computed that this will be heavier on the CPU but it seems a bit excessive?

Help for filter in openldap server
by baalchina 09 Jan '23

09 Jan '23

Hi, all I had a old openldap server from my colleague, and I am studying the server. I found a strange problem, when I using client(ldapadmin in Windows), I can filter by uid, objectClass,sn or anything else, but except inetUserStatus. For example, when I searching by 'sn=*', or 'sn=Jim', which jim is the exact name of my user, I will got the correct result. But when I searching by 'inetUserStatus=Inactive' or 'inetUserStatus=Active', nothing happens. I also tried 'inetUserStatus=*', and got the whole ldap users. The same happens in the memberOf attribute, which 'memberOf=*' got the whole users, and 'memberOf=cn=ABC*' got nothing. (My ldap users all have a attribute of 'memberOf: cn=ABC,ou=Groups,dc=abc,dc=cn'. So, what should I do if I want to using this two attribute memberOf and inetUserStatus? Thanks a lot. -- from:baalchina

09 Jan '23

Hi All, We are seeing very slow MOD operations on our ldap (250 MB data dump), while using mdb (data.mdb is 6.4 Gb). The average MOD operation is going to 8-9 seconds. We are seeing 1k disk ops and 6-7MB/s writes. The disk is 4096 IOPS Sata SSD, we have seen write speed to be 126 MB/s generally. The slapd version is slapd (May 14 2022 18:35:44). We the following olcDbIndex for eq: objectClass, entryCSN , entryUUID eq, uid , uidNumber , uniqueMember ,gidNumber , memberUid ,displayName ,cn ,sn , member, source , supervisor ,accountExpiryDate And, sortVals for memberUid and member.

OpenLDAP stats logging performance degradation
by Christopher Paul 03 Jan '23

03 Jan '23

Hello OpenLDAP-Technical, Using the oldie but goodie LDAP performance testing tool, SLAMD, I've been doing performance tests. What I found was that stats logging (olcLogLevel: 256) degrades performance significantly. A pity, because it is recommended in the manual. Also, it considered very useful by those of us who've been running OpenLDAP for a while. The test was performed on Dell Workstation Intel Xeon E-2630 v3 @ 2.40Ghz Xen 4.6.5 hypervisor running Linux 4.4.0 Ubuntu 16.04, 4 vcpus pinned to the hypervisor and the other 12 pinned to the OpenLDAP VM. The OpenLDAP VM was allocated 8GB RAM and runs OpenLDAP 2.5.13 (Symas RPM build) on RedHat 8.7. Ten thousand fake users were created in an OU=FakePeople for testing. I am aware that contention with disk I/O can cause problems, so I tried eliminating systemd-journald and rsyslogd in order to test "pure OpenLDAP" response times but was not perfectly successful. I ran slapd in the foreground using "slapd -d 256 ... 2>/dev/null". But then I noticed that systemd-journald still was logging to "session-4.scope". I tried "systemctl stop systemd-journald" and "systemctl stop systemd-journald.socket" and "systemctl stop systemd-journald-dev-log.socket" but was not able to stop systemd-journald from showing up using CPU in "htop". I tried limiting it also by setting RateLimitIntervalSec=1s and RateLimitBurst=1 in /etc/system/journald.conf. This reduced the logging but I still saw "/usr/lib/system/systemd-journald" taking 100% of one vcpu during the performance tests whenever olcLogLevel was set to 256. The test results I will include with this post are from the Asynchronous Search Rate SLAMD job class using LDAPSearch filters of valid random values for indexed attributeTypes "uid" and "mail" matching exact filters (equality match). Using LogLevel 256, the Asynchronous Search Rate test with 3 clients, 2 connection threads each (from laptop i7-1280P vPro Processor), OpenLDAP returned an average 10,932 results completed per second with err=0 and average 21ms response time. Then I ran ldapmodify to changetype: replace olcLogLevel to 0, reran the same test, and saw OpenLDAP perform much better. The same test with olcLogLevel=0 returned 84,286 results per second with err=0 (671% increase) and average response time of 2.6 ms (88% decrease). Watching "htop" during this test showed all vcpus firing a lot more evenly and hotter than the test with olcLogLevel=256; it was very clear how efficient slapd can be without having to do any logging. I ran several samples of each test and picked the best for each of olcLogLevels I tested. I ran other tests like 3 and 4 clients times 50 connections each, also ran Basic Bind Rate and saw similar patterns there. I don't mind sharing my configs or the test data if anyone is interested. And so naturally, I am wondering if this is a known limitation and also whether it is something that can be addressed or is a hard constraint. I guess I had expected some impact as a result of logging (nothing comes for free...) but not this much. Thanks, Chris Paul | Rex Consulting | https://www.rexconsulting.net

The final version should be that the binduser uid=lloadd will not see anything. So what's the point I'm missing to get proxyauthz work correctly?
