1171357 – Bind DN tracking unable to write to internalModifiersName without special permissions

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.

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47950


I've activated bind dn tracking (nsslapd-plugin-binddn-tracking: on). There is an account that has the write to add the entries and to change some attributes (e.g. description). The corresponding ACI:
{{{
dn: ou=Cours,ou=Enseignement,ou=Groupes,dc=id,dc=polytechnique,dc=edu
aci: (targetattr = "objectClass || uniqueMember || owner || cn || description || businessCategory" ) (version 3.0;acl "Droits de rejouter/supprimer/modifier les groupes et leurs att
ributs";allow (add, delete, read,compare,search,write)(userdn="ldap:///uid=sync-cours,ou=Comptes generiques,ou=Utilisateurs,dc=id,dc=polytechnique,dc=edu");)
}}}

Any attempt to modify an authorized attribute from the list above (for ex., description) results in

{{{
ldap_modify: Insufficient access (50)
        additional info: Insufficient 'write' privilege to the 'internalModifiersName' attribute of entry 'cn=mec431-2014,ou=2014,ou=cours,ou=enseignement,ou=groupes,dc=id,dc=polytechnique,dc=edu'.

}}}
{{{

The workaround is to add to all the ACIs that allow modifications the right to modify internalModifiersName attribute (if i add it, everything is fine and the attribute internalModifiersName becomes "cn=ldbm database,cn=plugins,cn=config").

Expected behavior : internalModifiersName should be written like modifiersname without  any explicit permission.
