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 Ján Rusnačko 2013-11-28 15:05:19 UTC 
Description of problem:
From RHEL 7 most DS plugins are converted to be betxn - if their operation fails, whole transaction should fail and not be comitted to database. In case of Auto Membership plugin, we can create a situation where plugin fails to add user to group, e.g. due to non-existent group entry.

Version-Release number of selected component (if applicable):
389-ds-base-1.3.1.6-8.el7.x86_64

How reproducible:
always

Steps to Reproduce:
1. Add definition entry:
ldapmodify -D "cn=directory manager" -w Secret123 -a <<EOF
dn: cn=testGroup,cn=Auto Membership Plugin,cn=plugins,cn=config
objectclass: autoMemberDefinition
autoMemberScope: ou=People,dc=example,dc=com
autoMemberFilter: cn=tuser
autoMemberDefaultGroup: cn=testgroup,ou=groups,dc=example,dc=com
autoMemberGroupingAttr: member:dn
EOF

Make sure cn=testgroup,ou=groups,dc=example,dc=com does not exist.

2. Add user:
ldapmodify -D "cn=directory manager" -w Secret123 -a <<EOF
dn: cn=tuser,ou=people,dc=example,dc=com
objectclass: person
objectclass: top
cn: tuser
sn: tuser
EOF

The operation is successful:
[jrusnack@localhost 6.0]$ ldapsearch -LLL -h localhost -p 34368 -D "cn=directory manager" -w Secret123 -b "cn=tuser,dc=autoMembers,dc=com"
dn: cn=tuser,dc=autoMembers,dc=com
objectClass: person
objectClass: top
cn: tuser
sn: tuser

Actual results:
[jrusnack@localhost 6.0]$ tail -n1 /var/log/dirsrv/slapd-dstet/errors
[28/Nov/2013:07:55:17 -0700] auto-membership-plugin - automember_add_member_value: Unable to add "cn=tuser,dc=automembers,dc=com" as a "member" value to group "cn=testgroup,dc=autoMembers,dc=com" (No such object).


Expected results:
User should not be added, if plugin operation fails.
