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 Rob Crittenden 2012-02-28 18:04:30 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/2452

We are not setting LDAP anonymous access limits correctly. This is an excerpt of ipaupgrade.log:

{{{
2012-02-27T15:59:56Z DEBUG add: 'dc=com' to nsslapd-anonlimitsdn, current value ['dc=com', u'cn=anonymous-limits', u'cn=etc', u'dc=idm', u'dc=lab', u'dc=bos', u'dc=redhat']
2012-02-27T15:59:56Z DEBUG add: updated value [u'cn=anonymous-limits', u'cn=etc', u'dc=idm', u'dc=lab', u'dc=bos', u'dc=redhat', u'dc=com']
}}}

`cn=anonymous-limits,cn=etc,SUFFIX` also does not contain the limits. Anonymous connections thus are not as restricted as they ought to be.
Comment 1 Rob Crittenden 2012-02-28 18:07:02 UTC 
We increase the server global limits to:

dn: cn=config,cn=ldbm database,cn=plugins,cn=config
nsslapd-lookthroughlimit:100000
nsslapd-idlistscanlimit:100000

The attempt to limit anonymous searches was incorrect but it should look like:

dn: cn=anonymous-limits,cn=etc,$SUFFIX
objectclass:nsContainer
objectclass:top
cn: anonymous-limits
nsSizeLimit: 5000

And in cn=config a pointer to this limit:

nsslapd-anonlimitsdn:cn=anonymous-limits,cn=etc,$SUFFIX
