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 Noriko Hosoi 2015-08-20 23:54:25 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/48252

    
1) Create the entry

    # ldapadd -cvvvv -D "cn=Directory Manager" -W -f /root/ldif/create-posix-user2.ldif
    ldap_initialize( <DEFAULT> )
    add objectClass:
            top
            account
            posixAccount
            shadowAccount
    add cn:
            Non Secure User
    add uid:
            user80
    add uidNumber:
            80
    add gidNumber:
            80
    add homeDirectory:
            /home/insecure
    add loginShell:
            /bin/bash
    add userpassword:
            {CLEAR}redhat
    adding new entry "uid=user80,ou=People,dc=coe,dc=muc,dc=redhat,dc=com"
    modify complete
  
2) Check the index file 
     
    # dbscan -f /var/lib/dirsrv/slapd-tscherf54/db/userRoot/gidNumber.db4 |grep "=80"
    =80                  

3) Delete the entry

    # ldapdelete -vx -D "cn=Directory Manager" -W "uid=user80,ou=People,dc=coe,dc=muc,dc=redhat,dc=com"
    ldap_initialize( <DEFAULT> )
    deleting entry "uid=user80,ou=People,dc=coe,dc=muc,dc=redhat,dc=com"

4) Verify the value from deleted entry has been removed from index
    
    # dbscan -f /var/lib/dirsrv/slapd-tscherf54/db/userRoot/gidNumber.db4 |grep "=80"
    #

5) Run db2index again 
     
    # /usr/lib64/dirsrv/slapd-tscherf54/db2index.pl  -n userRoot -D "cn=Directory Manager" -W -t gidNumber
    adding new entry "cn=db2index_2015_8_19_10_34_41, cn=index, cn=tasks, cn=config"

6) Value from removed entry shows up in index file again
     
    # dbscan -f /var/lib/dirsrv/slapd-tscherf54/db/userRoot/gidNumber.db4 |grep "=80"
    =80

7) ldapsearch fails to find the removed entry and there is also nothing related in the error log:

# ldapsearch -x  gidNumber=80
# extended LDIF
#
# LDAPv3
# base <dc=coe,dc=muc,dc=redhat,dc=com> (default) with scope subtree
# filter: gidNumber=80
# requesting: ALL
#

# search result

Comment 3 Kamlesh 2016-07-07 09:59:03 UTC 
Bug Verified

1) Create the entry
[root@test dirsrv]# ldapadd -D "cn=Directory Manager" -w test1234 -p 389 -h localhost -f /tmp/user2.ldif 
adding new entry "uid=user80,ou=People,dc=example,dc=com"
 

2) Check the index file 
[root@test dirsrv]# dbscan -f /var/lib/dirsrv/slapd-test/db/userRoot/cn.db | grep =user80
=user80           

3) Delete the entry

   [root@test dirsrv]# ldapdelete -vx -D "cn=Directory Manager" -w test1234 -p 389 -h localhost "uid=user80,ou=People,dc=example,dc=com"
ldap_initialize( ldap://localhost:389 )
deleting entry "uid=user80,ou=People,dc=example,dc=com"

4) Verify the value from deleted entry has been removed from index
    
   [root@test dirsrv]# dbscan -f /var/lib/dirsrv/slapd-test/db/userRoot/cn.db | grep =user80

5) Run db2index again 
     
[root@test dirsrv]# /usr/lib64/dirsrv/slapd-test/db2index.pl -n userRoot -D "cn=Directory Manager" -w test1234 -t cn.db
Successfully added task entry "cn=db2index_2016_7_7_15_29_50, cn=index, cn=tasks, cn=config"
    
6) Value from removed entry shows up in index file again
 [root@test dirsrv]# dbscan -f /var/lib/dirsrv/slapd-test/db/userRoot/cn.db | grep =user80

7) ldapsearch fails to find the removed entry and there is also nothing related in the error log:
[root@test dirsrv]# ldapsearch -D "cn=Directory Manager" -b "dc=example,dc=com" -h localhost -p 389 -w test1234 "(cn=user80)"
# extended LDIF
