RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description rick.beldin@hpe.com 2016-09-21 17:34:35 UTC

Same issue on RHEL 7.3 beta document 

Section Number and Name: 

9.3.2   Changing the Database-Specific Configuration
By default, the OpenLDAP server uses Berkeley DB (BDB) as a database back end. 
The configuration for this database is stored in the 
/etc/openldap/slapd.d/cn=config/olcDatabase={1}bdb.ldif file. 


Describe the issue: 

The file does not exist. 

# pwd
/etc/openldap/slapd.d/cn=config
[root@rhel72-ldap cn=config]# ls -1
cn=schema
cn=schema.ldif
olcDatabase={0}config.ldif
olcDatabase={-1}frontend.ldif
olcDatabase={1}monitor.ldif
olcDatabase={2}hdb.ldif


Suggestions for improvement: 

Document the files delivered and the defaults.  The man page for SLAPD-BDB says: 

     The  bdb backend to slapd(8) uses the Oracle Berkeley DB (BDB) package to
       store data.  It makes extensive use of indexing and caching to speed data
       access.

       Note  that BDB is deprecated and support will be dropped in future OpenL‐
       DAP releases. Installations should use the mdb backend instead.

This is not reflected in the documentation.

  Doc issue only in RHEL 7.3 beta documentation. 

7.2 doesn't have the chapter.

Thank you for the report. Marc, can you please look into this?

Comment 5 Marc Muehlfeld 2016-09-29 13:47:04 UTC

I updated the "Database-Specific Configuration" section. It shows now the correct file name, describes the correct default database back end (hdb), and notes that BDB is deprecated.

Additionally I added short sections to describe the other two files in /etc/openldap/slapd.d/cn=config/: olcDatabase={-1}frontend.ldif and olcDatabase={1}monitor.ldif

We will republish the updated guide after RHEL 7.3 GA (2016-10-25). 

Please note that we are currently thinking about moving the OpenLDAP chapter back to the System Administrator's Guide. In this case look for the updated section in the System Administrator's Guide after GA.

Comment 7 rick.beldin@hpe.com 2016-09-29 14:57:04 UTC

I think moving this back to the Sys Admin Guide might not be a bad idea. 

If you do, I think you need to beef up the section on setting this up.  The OpenLdap 2.4 configuration files are considerably different than before and the information is insufficient for someone to follow and have a minimal functioning LDAP server.   Most of the existing documentation consists of making edits to /etc/openldap/slapd.conf, which is now deprecated.   The 'new' way of doing things is to use ldapmodify, but basic instructions on how to change the rootDN password and other other basic attributes are unclear.
