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 of problem:

Replication is encrypting credentials of replication bind user password using DES plugin.

This is considered as insecure as for:

Comment 10 Sankar Ramalingam 2016-11-18 08:54:03 UTC 
1). Checking the default encryption type for replica passwords, with older version of 389-ds-base.
[root@auto-hv-02-guest09 MMR_WINSYNC]# rpm -qa |grep -i 389-ds
389-ds-base-libs-1.2.11.15-74.el6.x86_64
389-ds-base-1.2.11.15-74.el6.x86_64

[root@auto-hv-02-guest09 MMR_WINSYNC]# ldapsearch -LLL -x -p 1189 -h localhost -D "cn=Directory Manager" -w Secret123 -b "cn=1189_to_2616_on_auto-hv-02-guest09.idmqe.lab.eng.bos.redhat.com,cn=replica,cn=\"dc=passsync,dc=com\",cn=mapping tree,cn=config" | grep -i nsDS5ReplicaCredentials 
nsDS5ReplicaCredentials: {DES}2mO8LgMr/w5ognn2BRK+gQ==

2). Upgrade to the latest RHEL-6.9 389-ds-base-1.2.11.15-85
[root@auto-hv-02-guest09 MMR_WINSYNC]# yum -y update 389-ds-base 389-ds-base-libs
[root@auto-hv-02-guest09 MMR_WINSYNC]# rpm -qa |grep -i 389-ds
389-ds-base-1.2.11.15-85.el6.x86_64
389-ds-base-libs-1.2.11.15-85.el6.x86_64

3). Running setup-ds.pl
[root@auto-hv-02-guest09 MMR_WINSYNC]# setup-ds.pl -u
[root@auto-hv-02-guest09 MMR_WINSYNC]# service dirsrv restart

4). Running ldapsearch to check if AES encryption is used.

[root@auto-hv-02-guest09 MMR_WINSYNC]# ldapsearch -LLL -x -p 1189 -h localhost -D "cn=Directory Manager" -w Secret123 -b "cn=1189_to_2616_on_auto-hv-02-guest09.idmqe.lab.eng.bos.redhat.com,cn=replica,cn=\"dc=passsync,dc=com\",cn=mapping tree,cn=config" |grep -i  nsDS5ReplicaCredentials 
nsDS5ReplicaCredentials: {AES-TUhNR0NTcUdTSWIzRFFFRkRUQm1NRVVHQ1NxR1NJYjNEUUVG

After upgrade, the default password storage scheme changed to AES. No issues with the restart of Directory servers. Hence, marking the bug as Verified.
