How to check AD group membership? – TheITBros (2023)

Active Directory security groups are used to grant users permissions to various domain services and resources. Therefore, to understand what permissions are assigned to a particular user in the AD domain, it is enough to look at the groups to which the user account belongs.

There are several administrative tools that allow you to view Active Directory group membership: AD graphical consoles, command line tools, and PowerShell cmdlets.

View Active Directory User Group Membership via GUI

The easiest and clearest way to see the list of direct user groups in Active Directory is to use the graphical pluginActive Directory Users and Computers snap-in(I bring).

1. Rundsa.mscaperitif;
2. Right click on the root of the domain and selectMeet;
3. Enter your username and clickfind now;
4. Open user properties and go tomemberpato;
5. This tab lists the groups to which the selected user belongs.

You can also view the list of user groups from the Active Directory Administrative Center console (dsac.exe).

1. Enter your username inglobal searchbent and beatenGet into;
2. Double-click on the user account you need and go to the "Member" tab;
3. Here you can see the list of groups that a specific user is a member of;
4. If a user is in a large number of groups, you can use a filter to search for them by name.

This method only displays the immediate groups that the user has been added to. if it is differentGrupo Active Directory(nested group) is added to any of these groups, it will not appear in the console. To list all user groups (including nested ones), you must use command line tools.

Checking AD group membership via command line

Membership in an Active Directory group can also be checked using the command line. Run the command:

network user USERNAME/domain

As you can see, the output of the command includes the domain (global group memberships) and local groups (local group memberships) of the user.

You can list the security groups that your account belongs to with the following command:

whoami /groups

Domain Group Member List:

Grupo de red "CorpAPPUuser" /DOMAIN

You can also use the gpresult tool to view the current membership of users. Run "gpresult /r" and under User Settings you will see the membership of the logged in user:

The user belongs to the following security groups

You can see the full list of user groups (including nested groups) using dsget. Instead of a username, you must enter your distinguished name:

user dsget "CN=Jon Brion,OR=Users,OR=UK,DC=theitbros,DC=com" -memberof –expand

If you want to get members of a specific security group, including nested group memberships, use the command:

grupa dsget „CN=NY-Managers,OU=Users,OU=NY,DC=theitbros,DC=com” –members -expand

When you need to do the reverse operation and list the groups that a given group belongs to, run:

dsget group "CN=NY-Managers,OU=Users,OU=NY,DC=theitbros,DC=com" –memberof -expand

You can view the members of a specific AD group usingdsqueryInet groupcommands:

dsquery group name "AllowUSB" | dsget group -members

He:

network group "AllowUSB" /domain

How to list AD group members using PowerShell?

You can also verify a user's AD group membership using the PowerShell cmdlets:Get ad user,Get-ADPrincipalGroupMembership, Get-ADGroup and Get-ADGroupMember. you needMódulo PowerShell Active Directoryinstalled on your computer to do so.

Advice. To use AD PowerShell on Windows 10 or Windows 11 desktop devices, the Remote Server Administration Tools must be installed.

Import the Active Directory PowerShell module into the current session:

import module activedirectory

You can use the Get-ADGroup or Get-ADGroupMember cmdlets to get a list of users in a group. For example, to find a group in a domain and display a list of users in it, you can use the command:

(Get-ADGroup -Filter {Name-like "*_AllowUSB"} -Properties Members | SELECT *).Miembros

The above command will only return the DN (Distinguished Name) of the users who are members of the group. if you need othersuser attributeson a group (for example, SID, SamAccountName, name, etc.), it's better to use the Get-ADGroupMember cmdlet:

Get-ADGroup -Filter {Name similar to "*_AllowUSB"} -Member Properties | Get-ADGroupMember

In the example above, we assume that you do not know the exact name of the group you are looking for. If you know the full name of the group, you can specify it as the Get-ADGroupMember parameter right away.

The Get-ADGroupMember cmdlet allows you to list the members of an AD group (members can be users, groups, and computers).

Show only usernames added to a specific AD group (including nested groups):

Get-ADGroupMember -Identity AllowUSB -Recursive | Name and surname

Use. The -Recursive option displays not only user accounts added directly to the AllowUSB group, but also users in groups that are members of that group (child group or nested group).

View group members with detailed information about each member:

Get-ADGroupMember -Identity AllowUSB | foreach { Obtener-Aduser $_ -Properties * }

You can only see some user attributes in a group:

Get-ADGroupMember - Recursive "Group Name" | ForEach {Get-ADUser -filter {samaccountname -eq $_.SamAccountName} -Properties displayName, Company, Title, Department } | Format-Table displayName,signature,department,title –AutoSize

The following example will display the email addresses of all users in the specified security group:

Get-ADGroupMember - Recursive "UK_IT_DEPT" | ForEach { Get-ADUser -filter {samaccountname -eq $_.SamAccountName} -Properties mail } | Sort mail object | Mail in table format

To count the number of users in an AD group, you should use the PowerShell Count method:

(Get-ADGroupMember -Identity "Domain Admins").Count

Find empty groups in Active Directory (containing no users):

Get-ADGroup-filter * | where {-No($_ | Get-ADGroupMember)} | pick a name

You can do the opposite task: enumerate users who don't belong to a specific AD group. The following PowerShell command will list all non-member domain usersnyGerentesGroup.

Get-ADuser -Filter * -Properties MemberOf | where { -No ($_.MemberOf -match "nyManagers") } | pick a name

You can also use a pipeOut-GridViewcmdlet to conveniently sort and filter the list of group members. Out-GridView allows you to present any PowerShell data set in a simple GUI. Withadd criteriaoptions, you can add different filters. To sort the table by any attribute, simply click the column name in the table header.

Get-ADGroupMember - Tożsamość ca_AllowUSB | Select object name, object class, distinguished name | Out-GridView

Get Active Directory Users group membership using PowerShell

You can list the Active Directory groups that a user is a member of by using the following commands:

Get-ADPrincipalGroupMembership jbrion | pick a name

lubricant

Get-ADUser jbrion -Member Properties | Select the property -ExpandMemberOf

Another way to get a list of all group members (explicit or implicit) is to use a method–recursive matchingoperator:

Get-ADUser -Filter {MemberOf -RecursiveMatch "CN=NY-Sales,OU=Groups,OU=NY,DC=theitbros,dc=com"}

If we are only interested in knowing if a certain user belongs to a certain group, we can proceed as follows:

Get-ADUser -Filter {MemberOf -RecursiveMatch "CN=NY-Sales,OU=Groups,OU=NY,DC=theitbros,dc=com"} -SearchBase "CN=User,OU=Users,OU=NY,DC= theitbros,DC=com"

You can filter by group name:

Get-ADPrincipalGroupMembership jbrion | where {$_ -like "*allow*"} | Sort object | select -Expand property name

You can use the complexLDAPfilters to get the membership of a nested group. For example, to get a complete list of groups a user account belongs to (including nested groups), use the command:

Get-ADGroup –LDAPFilter (member: 1.2.840.113556.1.4.1941: =CN = John Brion, OU = Empleados, OU = NY, DC = theitbros, DC = com)

The following PowerShell script template can be used to verify a user's membership in a specific Active Directory group and perform certain actions based on the group's membership (the group name must be enclosed in * characters):

$group = "*AllowUSB*" $user = "jbrion" if ((Get-ADUser $user -Properties member of).member of -like $group* ) { # If the user is a member of the echo group "True" } Else { # Outgroup user echo "False" }

Export Active Directory group members using PowerShell

We previously showed you how to get AD group membership using PowerShell. In some cases, you must export the resulting list of users or groups to a text or CSV file.

To save a list of users that a user is a member of to a plain text file, simply redirect the output of the command to a file using the >> operator. For example:

Get-ADUser j.brion -Properties Member | Select -ExpandMember propertyOf >> c:\ps\ad_group.txt

As a result, a text file will appear in the specified directory with the distinguished name of all the groups to which the user belongs.

To export PowerShell objects to CSV format, useExport CSVcmdlets. All you need to do is use a pipeline to pass the output of the above command to the Export-Csv cmdlet.

Let's download a list of users from the pool and export this list to a CSV file.

Get-ADPrincipalGroupMembership j.brion | Select Object Name, Description, Group Category, Group Scope, Distinguished Name | Export-Csv -NoTypeInformation c:\ps\ad_group.csv -UTF8 Encoding

Remember that you can use the callsCmdlet Select Objectto get only the attributes of the PowerShell objects whose values ​​you want to export to CSV.
