Get-AdmObject

Gets one or more Active Directory objects.



Description

The Get-AdmObject cmdlet gets an Active Directory object or performs a search to retrieve multiple objects.

The Identity parameter specifies the Active Directory object to get. You can identify the object by its distinguished name (DN) or GUID. You can also set the parameter to an Active Directory object variable, such as $<localAdmObject> or pass an object through the pipeline to the Identity parameter.

To search for and retrieve more than one object, use the Filter or LDAPFilter parameter. The Filter parameter uses the PowerShell Expression Language to write query strings for Active Directory. PowerShell Expression Language syntax provides rich type conversion support for value types received by the Filter parameter. If you have existing LDAP query strings, you can use the LDAPFilter parameter.

This cmdlet gets a default set of Active Directory object properties. To get additional properties, use the Properties parameter.

Examples

Example 1: Get sites for a domain using an LDAP filter

Get-AdmObject -LDAPFilter "(objectClass=site)" -SearchBase 'CN=Configuration,DC=Fabrikam,DC=Com'  | FT Name -A

Name
----
HQ
BO1
BO2
BO3

This command displays the list of sites for Fabrikam using LDAP filter (objectClass=site).

Example 2: Get sites from the configuration naming context

Get-AdmObject -Filter 'ObjectClass -eq "site"' -SearchBase 'CN=Configuration,DC=Fabrikam,DC=Com' -Properties siteObjectBL | foreach {$_.siteObjectBL}

CN=192.167.1.0/26,CN=Subnets,CN=Sites,CN=Configuration,DC=FABRIKAM,DC=COM  
CN=192.166.1.0/26,CN=Subnets,CN=Sites,CN=Configuration,DC=FABRIKAM,DC=COM  
CN=192.168.1.0/26,CN=Subnets,CN=Sites,CN=Configuration,DC=FABRIKAM,DC=COM  
CN=192.165.1.0/26,CN=Subnets,CN=Sites,CN=Configuration,DC=FABRIKAM,DC=COM  
CN=192.164.1.0/26,CN=Subnets,CN=Sites,CN=Configuration,DC=FABRIKAM,DC=COM  
CN=192.163.1.0/26,CN=Subnets,CN=Sites,CN=Configuration,DC=FABRIKAM,DC=COM  

This command gets the Site objects from the configuration naming context and displays a list of siteObjectBL properties.

Example 3: Get all objects with a specified attribute

$ChangeDate = New-Object DateTime(2008, 11, 18, 1, 40, 02)
Get-AdmObject -Filter {whenChanged -gt $ChangeDate}

This command gets all the objects whose whenChanged property is greater than the specified date.

Parameters

-AdaxesService

Specifies the DNS name of an Adaxes service that will be used to execute this cmdlet. If this parameter is not specified, and the cmdlet is running from an Adaxes Active Directory provider drive, the value for this parameter can be determined from the current path. For example, if the current path is Adaxes:/example.com, the Adaxes service on example.com will be used. If the parameter is not specified and the service DNS name can’t be determined from the current path, the cmdlet will access Active Directory directly.

  • Type:
  • String

  • Position:

  • Named

  • Required:

  • False

  • Default Value:

  • None

  • Accept pipeline input:

  • False

  • Accept wildcard characters:

  • False

-Credential

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

To specify this parameter, you can type a user name, such as “User1” or “Domain01\User01” or you can specify a PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password.

You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can then set the Credential parameter to the PSCredential object.

If the acting credentials do not have permission to perform the task, Adaxes Active Directory PowerShell returns a terminating error.

  • Type:
  • PSCredential

  • Position:

  • Named

  • Required:

  • False

  • Default Value:

  • None

  • Accept pipeline input:

  • False

  • Accept wildcard characters:

  • False

-Filter

Specifies a query string that retrieves Active Directory objects. This string uses the PowerShell Expression Language syntax. The PowerShell Expression Language syntax provides rich type-conversion support for value types received by the Filter parameter. The syntax uses an in-order representation, which means that the operator is placed between the operand and the value.

Syntax:

The following syntax uses Backus-Naur form to show how to use the PowerShell Expression Language for this parameter.

<filter> ::= “{” <FilterComponentList> “}”

<FilterComponentList> ::= <FilterComponent> | <FilterComponent> <JoinOperator> <FilterComponent> | <NotOperator> <FilterComponent>

<FilterComponent> ::= <attr> <FilterOperator> <value> | “(” <FilterComponent> “)”

<FilterOperator> ::= “-eq” | “-le” | “-ge” | “-ne” | “-lt” | “-gt”| “-approx” | “-bor” | “-band” | “-recursivematch” | “-like” | “-notlike”

<JoinOperator> ::= “-and” | “-or”

<NotOperator> ::= “-not”

<attr> ::= <PropertyName> | <LDAPDisplayName of the attribute>

<value>::= <compare this value with an <attr> by using the specified <FilterOperator>>

  • Type:
  • String

  • Position:

  • Named

  • Required:

  • True

  • Default Value:

  • None

  • Accept pipeline input:

  • False

  • Accept wildcard characters:

  • False

-Identity

Specifies an Active Directory computer object by providing one of the following property values. The identifier in parentheses is the LDAP display name for the attribute.

Possible values for this parameter are:

  • Distinguished name (distinguishedName)
  • GUID (objectGUID)

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 an object through the pipeline or you can set the parameter to an object instance.

  • Type:
  • ADObject

  • Position:

  • 1

  • Required:

  • True

  • Default Value:

  • None

  • Accept pipeline input:

  • True (ByValue)

  • Accept wildcard characters:

  • False

-LDAPFilter

Specifies an LDAP query string that is used to filter Active Directory objects. You can use this parameter to run your existing LDAP queries. The Filter parameter syntax supports the same functionality as the LDAP syntax.

  • Type:
  • String

  • Position:

  • Named

  • Required:

  • True

  • Default Value:

  • None

  • Accept pipeline input:

  • False

  • Accept wildcard characters:

  • False

-Partition

Specifies the distinguished name of an Active Directory partition. The distinguished name 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.

In many cases, a default value will be used for the Partition parameter if no value is specified. The rules for determining the default value are given below. Note that rules listed first are evaluated first, and once a default value can be determined, no further rules will be evaluated.

  • 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 Adaxes Active Directory provider drive, the default value of Partition is automatically generated from the current path in the drive.
  • If none of the previous cases apply, the default value of Partition will be set to the default partition or naming context of the target domain.
  • Type:
  • String

  • Position:

  • Named

  • Required:

  • False

  • Default Value:

  • None

  • Accept pipeline input:

  • False

  • Accept wildcard characters:

  • False

-Properties

Specifies the properties of the output object to retrieve from the server. Use this parameter to retrieve properties that are not included into the default set.

Specify properties for this parameter as a comma-separated list of names. To display all of the attributes that are set on the object, specify * (asterisk).

To specify an individual extended property, use the name of the property. For properties that are not default or extended properties, you must specify the LDAP display name.

To retrieve properties and display them for an object, you can use the Get- cmdlet associated with the object and pass the output to the Get-Member* cmdlet.

  • Type:
  • String[]

  • Position:

  • Named

  • Required:

  • False

  • Default Value:

  • None

  • Accept pipeline input:

  • False

  • Accept wildcard characters:

  • False

  • Named

  • Required:

  • False

  • Default Value:

  • None

  • Accept pipeline input:

  • False

  • Accept wildcard characters:

  • False

-ResultSetSize

Specifies the maximum number of objects to return for an Active Directory Domain Services query. If you want to receive all of the objects, set this parameter to $Null (null value). You can use Ctrl+C to stop the query and return of objects.

The default is $Null.

  • Type:
  • Int32

  • Position:

  • Named

  • Required:

  • False

  • Default Value:

  • None

  • Accept pipeline input:

  • False

-SearchBase

Specifies an Active Directory path to search under.

When you run a cmdlet from an Adaxes Active Directory provider drive, the default value of this parameter is the current path of the drive.

When you run a cmdlet outside of an Adaxes Active Directory provider drive, the default value of this parameter is the default naming context of the target domain.

The following example shows how to set this parameter to search under an OU.

-SearchBase "ou=mfg,dc=noam,dc=corp,dc=contoso,dc=com"

When the value of the SearchBase parameter is set to an empty string and you are connected to a GC port, all partitions will be searched. If the value of the SearchBase parameter is set to an empty string and you are not connected to a GC port, an error will be thrown.

  • Type:
  • String

  • Position:

  • Named

  • Required:

  • False

  • Default Value:

  • None

  • Accept pipeline input:

  • False
