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 Brian J. Atkisson 2017-12-18 20:41:07 UTC 
Description of problem:

The IPA client installer currently edits /etc/openldap/ldap.conf, setting up the client to consume LDAP data from IPA.  It currently sets:

URI
BASE
TLS_CACERT

It really should also add:

SASL_MECH GSSAPI
TLS_REQCERT demand


The IPA client installer assumes the client will only be speaking LDAP to IPA, so might as well secure that connection as much as possible by default.
Comment 3 Florence Blanc-Renaud 2017-12-20 14:42:05 UTC 
Hi,

1- SASL-MECH option:
according to ldap.conf(5) man page, SASL_MECH option is a *user-only* option, which means that it cannot be set in ldap.conf:

-----
Some options are user-only.  Such options are ignored if present in the ldap.conf (or file specified by LDAPCONF).
[...]
       SASL_MECH <mechanism>
              Specifies the SASL  mechanism  to  use.   This  is  a  user-only
              option.
-----


2- TLS_REQCERT option:
according to ldap.conf man page, the default setting is "demand":

-----
       TLS_REQCERT <level>
              Specifies what checks to perform on server certificates in a TLS
              session, if any. The <level> can be specified as one of the fol‐
              lowing keywords:
[...]
              demand | hard
                     These keywords are equivalent. The server certificate  is
                     requested.  If  no certificate is provided, or a bad cer‐
                     tificate is provided, the session is  immediately  termi‐
                     nated. This is the default setting.

-----

With the above information, do you agree that we can close this RFE?
Comment 4 Brian J. Atkisson 2017-12-20 14:52:40 UTC 
1 - SASL-MECH absolutely gets applied, as defined in /etc/openldap/ldap.conf, when a user runs a ldap{search,modify,delete,whatever} from the CLI. This is the use-case that I want to target by this change.

2 - If TLS_REQCERT demand is the current default, that is fine, ignore #2 :)

I would say #1 still makes sense to do. We routinely have to instruct users to set it.
Comment 5 Florence Blanc-Renaud 2017-12-20 15:58:38 UTC 
You are right, despite what the man page says, SASL_MECH can be set in /etc/openldap/ldap.conf and works.

We'll discuss this RFE with the team.
