4732: A member was added to a security-enabled local group
On this page
The user in Subject: added the user/group/computer in Member: to the Security Local group in Group:.
This event is logged on domain controllers for Active Directory domain local groups and member computer for local SAM groups. You can determine if the group is a domain or SAM group by comparing Group Domain: to the Computer: name. If they match you have a SAM group, if they differ you have a domain group.
Active Directory
In Active Directory Users and Computers "Security Enabled" groups are simply referred to as Security groups. AD has 2 types of groups: Security and Distribution. Distribution (security disabled) groups are for distribution lists in Exchange and cannot be assigned permissions or rights. Security (security enabled) groups can be used for permissions, rights and as distribution lists. A domain local group means the group can only be granted access to objects within its domain but can have members from any trusted domain.
Local SAM
All groups are security groups in the computer's SAM. Local SAM groups can be granted access to objects on the local computer only but may have members from the local SAM and any trusted domain.
Server 2016 adds the "Expiration time" field in version 2 of this event.
