Global group membership windows

Hi All! I am working on excactly this problem these days and cannot find any other. Clarification would be really a very good thing!! BTW, I found this in technet: Because a domain local group is associated with an access token built when a member of that group authenticates to a resource in that domain, unnecessary network traffic carrying of membership information is avoided. If, instead, you assigned a global group permission to access the printer, the global group can end up in a user's token anywhere in the forest , causing unnecessary network traffic.

In our company, we have only one domain for the whole world [with several DCs per country]. Regards, scamb. Tuesday, February 23, PM. I wish someone had more info on this. My questions are: 1.

Why it is not a good idea to use Globla group to assign permissions? Wednesday, August 4, PM. Best wishes, Bod. Monday, August 9, AM. Monday, August 9, PM. Wednesday, November 27, PM. Global Groups always take up 8 bytes in the token. Domain Local Groups is more or less a must over forest trusts.

We needed to do that to about 4 security groups. Those groups need to be members of other groups, which in some cases need to be members of further groups still. As you can't make a universal group a member of a global or domain group, and you can't make a global a member of a domain group, as soon as you need one Universal group everything above it in the membership tree needs to be made Universal as well.

Completely daft. I'm just glad we're as small as we are, it must turn into a right headache for anyone for whom making everything Universal generates prohibitive amounts of replication traffic.

You can use Group Policy to assign user rights to security groups to delegate specific tasks. Permissions are different than user rights.

Permissions are assigned to the security group for the shared resource. Permissions determine who can access the resource and the level of access, such as Full Control. Some permissions that are set on domain objects are automatically assigned to allow various levels of access to default security groups, such as the Account Operators group or the Domain Admins group.

Security groups are listed in DACLs that define permissions on resources and objects. When assigning permissions for resources file shares, printers, and so on , administrators should assign those permissions to a security group rather than to individual users. The permissions are assigned once to the group, instead of several times to each individual user.

Each account that is added to a group receives the rights that are assigned to that group in Active Directory, and the user receives the permissions that are defined for that group. Like distribution groups, security groups can be used as an email entity. Sending an email message to the group sends the message to all the members of the group. Groups are characterized by a scope that identifies the extent to which the group is applied in the domain tree or forest.

The scope of the group defines where the group can be granted permissions. The following three group scopes are defined by Active Directory:. In addition to these three scopes, the default groups in the Builtin container have a group scope of Builtin Local. This group scope and group type cannot be changed. The following table lists the three group scopes and more information about each scope for a security group.

Special identity groups do not have specific memberships that can be modified, but they can represent different users at different times, depending on the circumstances. For information about all the special identity groups, see Special Identities. Default groups, such as the Domain Admins group, are security groups that are created automatically when you create an Active Directory domain. You can use these predefined groups to help control access to shared resources and to delegate specific domain-wide administrative roles.

Many default groups are automatically assigned a set of user rights that authorize members of the group to perform specific actions in a domain, such as logging on to a local system or backing up files and folders. For example, a member of the Backup Operators group has the right to perform backup operations for all domain controllers in the domain. When you add a user to a group, the user receives all the user rights that are assigned to the group and all the permissions that are assigned to the group for any shared resources.

Default groups are located in the Builtin container and in the Users container in Active Directory Users and Computers. The Builtin container includes groups that are defined with the Domain Local scope. The Users includes contains groups that are defined with Global scope and groups that are defined with Domain Local scope. You can move groups that are located in these containers to other groups or organizational units OU within the domain, but you cannot move them to other domains. Some of the administrative groups that are listed in this topic and all members of these groups are protected by a background process that periodically checks for and applies a specific security descriptor.

This descriptor is a data structure that contains security information associated with a protected object. This process ensures that any successful unauthorized attempt to modify the security descriptor on one of the administrative accounts or groups will be overwritten with the protected settings. The security descriptor is present on the AdminSDHolder object. This means that if you want to modify the permissions on one of the service administrator groups or on any of its member accounts, you must modify the security descriptor on the AdminSDHolder object so that it will be applied consistently.

Be careful when you make these modifications because you are also changing the default settings that will be applied to all of your protected administrative accounts. The following tables provide descriptions of the default groups that are located in the Builtin and Users containers in each operating system. Members of this group can remotely query authorization attributes and permissions for resources on the computer. The Account Operators group grants limited account creation privileges to a user.

Members of this group can create and modify most types of accounts, including those of users, local groups, and global groups, and members can log in locally to domain controllers. Members of the Account Operators group cannot manage the Administrator user account, the user accounts of administrators, or the Administrators , Server Operators , Account Operators , Backup Operators , or Print Operators groups.

Members of this group cannot modify user rights. By default, this built-in group has no members, and it can create and manage users and groups in the domain, including its own membership and that of the Server Operators group.

This group is considered a service administrator group because it can modify Server Operators, which in turn can modify domain controller settings. As a best practice, leave the membership of this group empty, and do not use it for any delegated administration. This group cannot be renamed, deleted, or moved. Members of the Administrators group have complete and unrestricted access to the computer, or if the computer is promoted to a domain controller, members have unrestricted access to the domain.

The Administrators group has built-in capabilities that give its members full control over the system. This built-in group controls access to all the domain controllers in its domain, and it can change the membership of all administrative groups. Membership can be modified by members of the following groups: the default service Administrators, Domain Admins in the domain, or Enterprise Admins. This group has the special privilege to take ownership of any object in the directory or any resource on a domain controller.

This account is considered a service administrator group because its members have full access to the domain controllers in the domain. Default user rights changes: Allow log on through Terminal Services existed in Windows Server , and it was replaced by Allow log on through Remote Desktop Services. Remove computer from docking station was removed in Windows Server R2.

This group has no members by default, and it results in the condition that new Read-only domain controllers do not cache user credentials. Members of the Backup Operators group can back up and restore all files on a computer, regardless of the permissions that protect those files.

Backup Operators also can log on to and shut down the computer. By default, this built-in group has no members, and it can perform backup and restore operations on domain controllers. Its membership can be modified by the following groups: default service Administrators, Domain Admins in the domain, or Enterprise Admins. It cannot modify the membership of any administrative groups. While members of this group cannot change server settings or modify the configuration of the directory, they do have the permissions needed to replace files including operating system files on domain controllers.

Because of this, members of this group are considered service administrators. Members of the Cert Publishers group are authorized to publish certificates for User objects in Active Directory. Members of the Cloneable Domain Controllers group that are domain controllers may be cloned. In Windows Server R2 and Windows Server , you can deploy domain controllers by copying an existing virtual domain controller. In a virtual environment, you no longer have to repeatedly deploy a server image that is prepared by using sysprep.

This security group was introduced in Windows Server , and it has not changed in subsequent versions. Members of this group are authorized to perform cryptographic operations. This security group was introduced in Windows Vista Service Pack 1, and it has not changed in subsequent versions.

The purpose of this security group is to manage a RODC password replication policy. This group contains a variety of high-privilege accounts and security groups. No Safe to move out of default container? Therefore, to understand what permissions are assigned to a specific user in the AD domain, it is enough to look at the groups in which the user account is a member.

As you can see, the command output contains the domain Global Group memberships and local groups Local Group Memberships of the user. The main drawback of the methods described above is that the nested AD groups are not displayed when the group is a member of other security groups. You can display a full list of user groups including nested ones using the dsget tool. You can find the group membership information in the last two line of this command output.

As you can see in these examples, thet net API localgroups functionality will happily list all members of a group. However the net user code completely ignores system accounts, as does most of the rest of what Windows makes available. This happens with LookupAccountSid as well. If you give it an SID like S, it will give you an answer.
