Get all the security groups in which an account is a direct or indirect member. The returned set does not include Distribution Groups but can include additional groups that the system would consider the user a member of for authorization purposes.

      Get-ADAccountAuthorizationGroup [-Identity] ADAccount
         [-AuthType {Negotiate | Basic}] [-Credential PSCredential]
            [-Partition string] [-Server string] [CommonParameters]

   -AuthType {Negotiate | Basic}
       The authentication method to use: Negotiate (or 0), Basic (or 1)
       A Secure Sockets Layer (SSL) connection is required for Basic authentication.

   -Credential PSCredential
       The user account credentials to use to perform this task.
       The default credentials are those of the currently logged on user unless the
       cmdlet is run from an Active Directory PowerShell provider drive.
       If the cmdlet is run from such a provider drive, the account associated with the drive is the default.

       Type a user name, such as "User64" or "Domain64\User64" or specify a
       PSCredential object such as one generated by Get-Credential 

       If a user name is specified, the cmdlet will prompt for a password.

    -Identity ADAccount
       An AD account object, provide one of the following values:
       (The identifier in parentheses is the LDAP display name for the attribute.)

          Distinguished Name 
            Example: CN=JaneJacobs,CN=Users,DC=corp,DC=SS64,DC=com
          GUID (objectGUID)
            Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
          Security Identifier (objectSid)
            Example: S-1-5-21-3165297888-301567370-576410423-1103
          SAM Account Name (sAMAccountName)
            Example: JaneJacobs

       The cmdlet searches the default naming context or partition to find the object.
       If two or more objects are found, the cmdlet returns a non-terminating error.

       This parameter can also get this object through the pipeline or you can set this
       parameter to an object instance.

       This example shows how to set the parameter to a distinguished name.
          -Identity  "CN=JaneJacobs,CN=Users,DC=corp,DC=SS64,DC=com"

       This example shows how to set this parameter to a optional feature object instance named "accountInstance".
          -Identity $accountInstance

   -Partition string
       The distinguished name of an AD partition.
       string must be one of the naming contexts on the current directory server.
       The cmdlet searches this partition to find the object defined by the -Identity parameter.
         -Partition "CN=Configuration,DC=EUROPE,DC=TEST,DC=SS64,DC=COM"
         -Partition "CN=Schema,CN=Configuration,DC=EUROPE,DC=TEST,DC=SS64,DC=COM"

       If the -Identity parameter is set to a distinguished name, the default value of -Partition
       is automatically generated from this distinguished name.
       If running cmdlets from an AD provider drive, the default value of -Partition is automatically
       generated from the current path in the drive.

   -Server string
       The AD Domain Services instance to connect to, this may be a Fully qualified domain name,
       NetBIOS name, Fully qualified directory server name (with or without port number)

       -Verbose, -Debug, -ErrorAction, -ErrorVariable, -WarningAction, -WarningVariable,
       -OutBuffer -OutVariable.

Get-ADAuthorizationGroup cmdlet gets the security groups from the specified user, computer or service accounts token. This cmdlet requires a global catalog to perform the group search. If the forest that contains the account does not have a global catalog, the cmdlet returns a non-terminating error.

The -Identity parameter specifies the user, computer, or service account. You can identify a user, computer, or service account object by its distinguished name (DN), GUID, security identifier (SID), Security Account Manager (SAM) account name or user principal name. You can also set the -Identity parameter to an account object variable, or through the pipeline. For example, you can retrieve an account object with Get-ADUser, Get-ADComputer, Get-ADServiceAccount or Search-ADAccount


Returns all security groups for the account with SamAccountName = StewartLee

PS C:\> Get-ADAccountAuthorizationGroup StewartLee

Returns all security groups for an account with the specified Distinguished Name:

PS C:\> Get-ADAccountAuthorizationGroup "cn=StewartLee,dc=SS64Guests"
