Openldap replication out of sync autobiography
•
Hi, I search a lot but can't find solution so I post here : I have to allow a user to get informations from internal ldap for enterprise external software (cloud backup for laptop). only some accounts have to be retreive by this external user. I create a group (posixgroup) and add members to this one (memberUid) I create the posixAccount that will be used by external software to get informations on the member of the new group. (uid,userPassword,mail,givenName,sn) so I want to make an acl that limit access for the create account to read only informations of users from the created group. I already test overlay memberOf but it's not working with memberUid (not dn style) info openldap server 2.4.40+dfsg-1 on debian jessie simple ldap ou=Users,dc=exemple,dc=com <-- all my users uid=readers,ou=Users,dc=exemple,dc=com <-- the user i want to use to see only cn=externalgroupaccess ou=Groups,dc=exemple,dc=com <-- posixGroup with memberUid cn=arcaboxUser,ou=Groups,dc=exemple,dc=com <-- the group that users have to be visible. acl : access to dn.subtree="dc=Comptes,dc=com" attrs=entry,uid,userPassword,mail,givenName,sn filter=() by dn="uid=readers,ou=Users,dc=exemple,dc=com" read by * break access to dn.subtree="dc=Comptes,dc=com" by dn

Black Lantern Security (BLSOPS)
A common favorite “domain domination” technique for Black Lantern Security (BLS) operators during engagements is to perform a DCSync attack to obtain all the juicy credentials they can acquire. Because this technique generally flies under the radar of detection and logging capabilities at most organizations, the first question from the client during outbrief always seems to be, “How did you do it?” In an effort to aggregate many of the community resources, research, and shared experience and to demystify some of this technique’s nitty gritty technical details in a digestible manner for our clients, we have put together a brief write up.
The DCSync attack methodology takes advantage of the Directory Replication Service Remote (DRSR) protocol to obtain sensitive information from a domain controller. This technique involves an adversary masquerading their host as a domain controller (DC) and convincing the authentic DC to synchronize its database to the new rogue DC by issuing a replication request. This functionality is not a bug, but rather is intended activity to provide user friendly redundancy in a multi-DC network. The attack does require elevated privileges to complete. The user account used to perform the data replication request must
