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 David Spurek 2011-07-25 15:23:30 UTC
Created attachment 515097 [details]
Slapd configuration file

Description of problem:
Overlay refint option refint_nothing doesn't function correctly. After delete the last value, an arbitrary value should be used as a placeholder. Attribute doesn't have an arbitrary value, but last value before delete.

Version-Release number of selected component (if applicable):
openldap-servers-2.4.23-15.el6

How reproducible:
always

Steps to Reproduce:
1.slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d/
(slapd.conf is in attachement)
2.add entry
dn: dc=my-domain,dc=com
objectClass: dcObject
objectClass: organization
dc: my-domain
o: my-domain
description: my-domain

dn: cn=Manager,dc=my-domain,dc=com
objectClass: organizationalRole
cn: Manager
description: Directory Manager

dn: ou=People,dc=my-domain,dc=com
objectClass: organizationalUnit
ou: People

dn: uid=ldap1,ou=People,dc=my-domain,dc=com
cn: ldap1
objectClass: account
objectClass: posixAccount
objectClass: top
uid: ldap1
uidNumber: 10001
gidNumber: 10001
homeDirectory: /home/ldap/ldap1
gecos: ldap1_user
loginShell: /bin/sh
userPassword: {SSHA}vXxC+eHHxf4p16273jJfK1xGrMSn+aUT

dn: uid=ldap2,ou=People,dc=my-domain,dc=com
cn: ldap2
objectClass: account
objectClass: posixAccount
objectClass: top
uid: ldap2
uidNumber: 10002
gidNumber: 10002
homeDirectory: /home/ldap/ldap2
gecos: uid=ldap1,ou=People,dc=my-domain,dc=com
loginShell: /bin/sh
userPassword: {SSHA}vXxC+eHHxf4p16273jJfK1xGrMSn+aUT
3.ldapdelete -x -D cn=Manager,dc=my-domain,dc=com -w x uid=ldap1,ou=People,dc=my-domain,dc=com
4.ldapsearch -LLL -b dc=my-domain,dc=com -x "(uid=ldap2)" gecos
  
Actual results:
dn: uid=ldap2,ou=People,dc=my-domain,dc=com
gecos: uid=ldap1,ou=People,dc=my-domain,dc=com

Expected results:
dn: uid=ldap2,ou=People,dc=my-domain,dc=com
gecos: cn=missing,dc=my-domain,dc=com

Additional info:
When option refint_nothing missing, the attribute gecos is correctly missing in entry uid=ldap2,ou=People,dc=my-domain,dc=com.

Comment 1 Jan Vcelak 2011-08-12 11:34:40 UTC
I found the problem, working on resolution.

bdb_modify: uid=ldap2,ou=People,dc=my-domain,dc=com
bdb_dn2entry("uid=ldap2,ou=people,dc=my-domain,dc=com")
bdb_modify_internal: 0x00000005: uid=ldap2,ou=People,dc=my-domain,dc=com
bdb_modify_internal: delete gecos
bdb_modify_internal: replace modifiersName
bdb_modify_internal: delete gecos
bdb_modify_internal: 16 modify/delete: gecos: no such attribute
bdb_modify: modify failed (16)
send_ldap_result: conn=-1 op=0 p=0
send_ldap_result: err=16 matched="" text="modify/delete: gecos: no such attribute"
refint_repair: dependent modify failed: 16
