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.

Doc Type: Enhancement
Doc Text:
Root DSE searches no longer display operational attributes by default Running the ldapsearch utility with the '-s base -b ""' options now displays only the user attributes and not the operational attributes. Previously, a root DSE search displayed all attributes by default. To ensure compatibility with earlier versions, this update adds the "nsslapd-return-default-opattr" attribute to the root DSE. You can modify the new default behavior by setting "nsslapd-return-default-opattr" in the dse.ldif configuration file as follows: dn: nsslapd-return-default-opattr: supportedsaslmechanisms nsslapd-return-default-opattr: nsBackendSuffix nsslapd-return-default-opattr: subschemasubentry nsslapd-return-default-opattr: supportedldapversion nsslapd-return-default-opattr: supportedcontrol nsslapd-return-default-opattr: ref nsslapd-return-default-opattr: vendorname nsslapd-return-default-opattr: vendorVersion nsslapd-return-default-opattr: namingcontexts nsslapd-return-default-opattr: supportedextension With this configuration, running the ldapsearch utility with '-s base -b ""' displays all attributes by default.

Description Noriko Hosoi 2014-07-09 21:10:46 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47761

A recent change in schema parsing ahd the side effect of changing the behavior of rootdse so that now it does not return all atributes by default.
Although this is more standards complaint it may break clients that are primarily tested against Active Directory.

In FreeIPA we feel we need a way to change the behavior through a cn=config option so that we can return to the old behavior and return all attributes that were previously returned (but not things like modifyTimestamps and such).
Comment 3 Ludwig 2014-10-23 13:40:38 UTC 
Operational attributes are no longer returned by default in rootDSE searches.
verify by 
ldapsearch ... -b "" -s base

and check that operational attributes like supportedcontrol or namincontexts are not returned.

To change default behaviour modify the rootDSE entry "dn: "

ldapmodify
dn: 
changetype: modify
add:nsslapd-return-default-opattr
nsslapd-return-default-opattr: namingContexts
nsslapd-return-default-opattr:supportedControl

repeat the above search

[root@vm-idm-035 MMR_WINSYNC]# ldapsearch -p 1189 -h localhost -D "cn=Directory Manager" -w Secret123 -b "" -s base
dn:
objectClass: top
defaultnamingcontext: dc=example,dc=com
dataversion: 020141120112723020141120112723
netscapemdsuffix: cn=ldap://dc=vm-idm-035,dc=lab,dc=eng,dc=pnq,dc=redhat,dc=co
 m:1189

[root@vm-idm-035 MMR_WINSYNC]# ldapmodify -p 1189 -h localhost -D "cn=Directory Manager" -w Secret123 << EOF
dn:
changetype: modify
add:nsslapd-return-default-opattr
nsslapd-return-default-opattr: namingContexts
nsslapd-return-default-opattr:supportedControl
EOF

modifying entry ""

[root@vm-idm-035 MMR_WINSYNC]# ldapsearch -p 1189 -h localhost -D "cn=Directory Manager" -w Secret123 -b "" -s base

dn:
objectClass: top
namingContexts: dc=example,dc=com
namingContexts: dc=passsync,dc=com
defaultnamingcontext: dc=example,dc=com
supportedControl: 2.16.840.1.113730.3.4.2
supportedControl: 2.16.840.1.113730.3.4.3
supportedControl: 2.16.840.1.113730.3.4.4

SupportedControl and naminContexts information is not shown default. After adding "nsslapd-return-default-opattr" attribute, the ldapsearch shows the values for SupportedControl and naminContexts. Hence, marking the bug as Verified.

Build tested:
[root@vm-idm-035 MMR_WINSYNC]# rpm -qa 389-ds-base
389-ds-base-1.3.3.1-9.el7.x86_64
Comment 5 Sankar Ramalingam 2014-11-24 16:57:50 UTC 
Changed the bug summary since the feature is actually to deny all rootdse attributes by default. You need to explicitly request or modify this attribute "nsslapd-return-default-opattr" to view rootdse entries.
