SystemDceSecurityProvider retrieves the user or group identifiers from the system

Methods

getUid

Returns a user identifier for the system

public getUid(): \Ramsey\Uuid\Type\Integer

getGid

public getGid(): \Ramsey\Uuid\Type\Integer

private hasShellExec(): bool

getOs

private getOs(): string

getWindowsUid

Returns the user identifier for a user on a Windows system

private getWindowsUid(): string

Windows does not have the same concept as an effective POSIX UID for the running script. Instead, each user is uniquely identified by an SID (security identifier). The SID includes three 32-bit unsigned integers that make up a unique domain identifier, followed by an RID (relative identifier) that we will use as the UID. The primary caveat is that this UID may not be unique to the system, since it is, instead, unique to the domain.

getWindowsGid

Returns a group identifier for a user on a Windows system

private getWindowsGid(): string

Since Windows does not have the same concept as an effective POSIX GID for the running script, we will get the local group memberships for the user running the script. Then, we will get the SID (security identifier) for the first group that appears in that list. Finally, we will return the RID (relative identifier) for the group and use that as the GID.
