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.

Fixed In Version: 389-ds-base-1.3.9.1-4.el7
Doc Type: If docs needed, set a value
Doc Text:
Cause: The upgrade script that rebuild the dse.ldif ignore entries starting with 'cn=->...' Consequence: if an replication agreement is named such a way 'cn=->...' it is removed and there is no more replication from the upgrade host to the consumer. Fix: By default if mozldap fails to normalize an entry DN, keep the entry in the dse.ldif Result: replication agreement starting with 'cn=->..' remain in the dse.ldif

Description German Parente 2018-08-30 13:38:12 UTC 
Description of problem:

when a replication agreement starts with "cn=->...", the upgrade is removing the entry.

I have checked upgrade from  1.3.6.1-26.el7_4 to 1.3.7.5-25.el7_5

I don't see yet what is removing the agremeent. It could be 

setup-ds.pl -u

but I have not seen yet the root cause.

Still checking.



Version-Release number of selected component (if applicable):  389-ds-base-1.3.7.5-25.el7_5



How reproducible: easily reproducible.

Comment 5 Akshay Adhikari 2019-03-28 09:44:03 UTC 
Build Tested on: 389-ds-base-1.3.9.1-3.el7.x86_64

Steps:

1) To perform an upgrade be on the older rpms.

[root@qeos-5 upstream]# rpm -qa | grep 389
389-ds-base-debuginfo-1.3.8.4-23.el7_6.x86_64
389-ds-base-libs-1.3.8.4-23.el7_6.x86_64
389-ds-base-snmp-1.3.8.4-23.el7_6.x86_64
389-ds-base-1.3.8.4-23.el7_6.x86_64

2) Create a working replication and search for the agreement.

[root@qeos-5 upstream]# ldapsearch -D "cn=Directory Manager" -p 39001 -h `hostname` -b "cn=->002,cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config" -w password

dn: cn=->002,cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config
objectClass: top
objectClass: nsds5replicationagreement
cn: 002
nsDS5ReplicaRoot: dc=example,dc=com
nsDS5ReplicaBindDN: cn=qeos-5.lab.eng.rdu2.redhat.com:63701,ou=Services,dc=exa
 mple,dc=com
nsDS5ReplicaBindMethod: simple

 TnhSMU5KWWpORVVVVkdSRVJCTkVKRFVtdGFWRlY1V2xSc2JWbDVNV3RPUkdoclRUSkpkdzBLVGxNe

3) Perform an upgrade to the latest packages.

[root@qeos-5 upstream]# yum update 389-ds-base*
  
[root@qeos-5 upstream]# rpm -qa | grep 389
389-ds-base-debuginfo-1.3.9.1-3.el7.x86_64
389-ds-base-libs-1.3.9.1-3.el7.x86_64
389-ds-base-snmp-1.3.9.1-3.el7.x86_64
389-ds-base-1.3.9.1-3.el7.x86_64

4) Try to search for the agreement again.

[root@qeos-5 upstream]# ldapsearch -D "cn=Directory Manager" -p 39001 -h `hostname` -b "cn=->002,cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config" -w password
# extended LDIF
#
# LDAPv3
# base <cn=->002,cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# search result
search: 2
result: 0 Success

# numResponses: 1

[root@qeos-5 upstream]# ldapsearch -D "cn=Directory Manager" -p 39001 -h `hostname` -b "cn=-\3E002,cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config" -w password
# extended LDIF
#
# LDAPv3
# base <cn=-\3E002,cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# search result
search: 2
result: 0 Success

# numResponses: 1

Observations:

1) The agreement is deleted even without running setup-ds.pl -u

2) Patch is not back-ported, file: /usr/lib64/dirsrv/perl/FileConn.pm does'nt have the changes.


Marking as failedQA.

3) Perform an upgrade to the latest packages.

[root@host-8-241-102 suites]# yum update 389-ds-base

4) Run the setup-ds.pl -u command to upgrade the instances.

[root@host-8-241-102 suites]# setup-ds.pl -u

5) Restart the instances if upgraded in Online mode.

6) Search for the replication agreement again.

[root@host-8-241-102 suites]# ldapsearch -D "cn=Directory Manager" -p 39001 -h `hostname` -b "cn=->002,cn=replica,cn=dc\3Dexample\2Cdc\3Dcom,cn=mapping tree,cn=config" -w password
