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
