Adversaries may attempt to find domain-level groups and permission settings. The knowledge of domain-level permission groups can help adversaries determine which groups exist and which users belong to a particular group. Adversaries may use this information to determine which users have elevated permissions, such as domain administrators.
Commands such as <code>net group /domain</code> of the Net utility, <code>dscacheutil -q group</code> on macOS, and <code>ldapsearch</code> on Linux can list domain-level groups.

This control's "Security principal reconnaissance (LDAP) (external ID 2038)" alert can be used to detect when an adversary "perform suspicious LDAP enumeration queries or queries targeted to sensitive groups that use methods not previously observed." This alert employs machine learning which should reduce the number of false positives.
Additionally, this control's "User and Group membership reconnaissance (SAMR) (external ID 2021)" alert can detect this sub-technique and also employs machine learning which should reduce the false-positive rate.
