openSUSE/SLE users, migrate to back-mdb now!
by Michael Ströder 27 Aug '21

27 Aug '21

HI! This is an important note to those who run OpenLDAP slapd based on openSUSE or SLE packages, especially Tumbleweed: If you're still using OpenLDAP 2.4 or earlier with back-bdb or back-hdb then migrate to back-mdb now because OpenLDAP 2.5 packages won't support these backends anymore! Disclaimer: I'm writing as a package maintainer who only updates package "openldap2" in openSUSE Factory/Tumbleweed. I have no official role in openSUSE project nor SUSE. Background: As you might already know OpenLDAP 2.5 builds by default have no more support for backends back-hdb and back-bdb based on Berkeley-DB. Furthermore using Berkeley-DB in general is deprecated. I've received a request to update the openSUSE package "openldap2" and its sub-packages to OpenLDAP release 2.5.7 also removing back-bdb and back-hdb [1]. I'd love to accept this update request really soon because I also want to have the new features in libldap. So the update will hit openSUSE Tumbleweed really soon. While this change will *not* affect your deployments based on packages from SLE or openSUSE Leap 15.3 or earlier you should prepare your installation for possible future updates by migrating to back-mdb now. And always use slapcat to backup your database(s) and practice restoring your databases to be prepared for any desaster. Ciao, Michael. [1] https://build.opensuse.org/request/show/914040

How to determine olcDbMaxSize
by Dave Macias 27 Aug '21

27 Aug '21

Hello, Playing around with moving from 2.4.59 hdb to 2.5.7 mdb. According to the admin page, one of the changes is adding olcDbMaxSize. Noticed that the default on 2.5.7 is: (1GB) olcDbMaxSize: 1073741824 My db does not come close to that but was curious how one can determine what the db size is currently ? Do you ls -h the /var/symas/openldap-data/data.mdb file ? Thank you, Dave

ah, yes, I see. I made a bad assumption that, when doing a "make" in the password module, that it would make everything there and under it, including subdirectories. going into sha2 under password and doing a make works fine. my bad. --- Regards, Kevin Martin On Thu, Aug 26, 2021 at 11:41 AM Quanah Gibson-Mount <quanah(a)symas.com> wrote: > > > --On Thursday, August 26, 2021 12:38 PM -0500 kevin martin > <ktmdms(a)gmail.com> wrote: > > > > > > > so I sb able to take the pw-sha2 module that I compiled for RHEL7 and > > simply move it over to RHEL8?

so I sb able to take the pw-sha2 module that I compiled for RHEL7 and simply move it over to RHEL8?

pw-ssha? I had a pw-sha2 module loaded but not pw-ssha. and the password module won't compile at this time because there's no radius-devel package for RHEL 8 that I can find in any repos. --- Regards, Kevin Martin On Thu, Aug 26, 2021 at 11:09 AM Quanah Gibson-Mount <quanah(a)symas.com> wrote: > > > --On Thursday, August 26, 2021 11:55 AM -0500 kevin martin > <ktmdms(a)gmail.com> wrote: > > > > > > > while trying to convert from a slapd.conf file to a cn=config style, > > slaptest displays the error as shown in the subject line. openldap 2.4 > > supported "password-hash {SHA512}" in the slapd.conf, is this simply an > > issue of password-hash not being able to be converted or is that > > *particular* password-hash line unsupported in the latest 2.5 (building > > from source)? > > It has always required that the pw-ssha contrib module exist and be loaded > in the configuration. 2.5 is no different than 2.4 in this. > > Regards, > Quanah > > > > -- > > Quanah Gibson-Mount > Product Architect > Symas Corporation > Packaged, certified, and supported LDAP solutions powered by OpenLDAP: > <http://www.symas.com> >

while trying to convert from a slapd.conf file to a cn=config style, slaptest displays the error as shown in the subject line. openldap 2.4 supported "password-hash {SHA512}" in the slapd.conf, is this simply an issue of password-hash not being able to be converted or is that *particular* password-hash line unsupported in the latest 2.5 (building from source)? --- Regards, Kevin Martin

Awesome! So then, if it's already shipped, why dont I see the schema files for ppolicy? Would have thought to find it here: /opt/symas/etc/openldap/schema > find /opt/ -name *ppolicy* /opt/symas/lib/openldap/ppolicy.la /opt/symas/lib/openldap/ppolicy.so /opt/symas/lib/openldap/ppolicy-2.5.so.0 /opt/symas/lib/openldap/ppolicy-2.5.so.0.1.2 /opt/symas/share/man/man5/slapo-ppolicy.5 Thank you again for the quick responses!
