Black Lantern säkerhet (BLSOPS)
A common favorite “domain domination” technique for Black Lantern säkerhet (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 tillsammans a brief write up.

User authentication with LDAP
Nextcloud ships with an LDAP application to allow LDAP users (including Active Directory) to appear in your Nextcloud user listings. These users will authenticate to Nextcloud with their LDAP credentials, so you don’t have to create separate Nextcloud user accounts for them. You will manage their Nextcloud group memberships, quotas, and sharing permissions just like any other Nextcloud user.
Note
The PHP LDAP module is required; this is supplied by on most distributions.
The LDAP application supports:
LDAP group support
File sharing with Nextcloud users and groups
Access via WebDAV and Nextcloud Desktop Client
Versioning, external Storage and all other Nextcloud features
Seamless connectivity to Active Directory, with no extra configuration required
Support for primary groups in Active Directory
Auto-detection of LDAP attributes such as base DN, email, and the LDAP server port number
Only read access to your LDAP (edit or
