Query Active Directory for a particular User

If you just want to know, for example, where a given user exists in your Active Directory, then searching for an account is a snap:
--- Begin code -----
cls
# sending LDAP query to Active Directory
#Change sAMAccountName for your query
$searcher = [ADSISearcher]'(&(objectClass=User)(objectCategory=person)(sAMAccountName=jpiggee*))'
# finding first match
$searcher.FindOne()
# finding ALL matches
$searcher.FindAll()
#This would find all user accounts with a SamAccountName that starts with "tobias". You can now use this approach to easily find out where an account is located:
# find account location
$searcher.FindAll() | Select-Object -ExpandProperty Path

---End Code ----

Get More Detailed Information Using GetDirectoryEntry()

To get more detailed information about an accounts using GetDirectoryEntry() to turn the search result into actual account objects:

# send LDAP query to Active Directory

$searcher = [ADSISearcher]'(&(objectClass=User)(objectCategory=person)(sAMAccountName=*))' 

# get 10 results max

$searcher.SizeLimit = 10 

# find account location

$searcher.FindAll() |

  # get account object

  ForEach-Object { $_.GetDirectoryEntry() } |

  # display all properties

  Select-Object -Property * |

  # display in a grid view window (ISE needs to be installed for this step)

  Out-GridView

Exchange 2010: Update the Global Address List(GAL)

You can use the Shell to update a global address list (GAL). A GAL is a directory that contains entries for every group, user, and contact within an organization's implementation of Microsoft Exchange.
1. Open the EMC Shell.
2. Run the following command:

Update-GlobalAddressList -Identity <GlobalAddressListIdParameter> –DomainController

* Note that this starts the process, but the completion could take 15 min. to a couplehours.

More Information:

Syntax:

update-GlobalAddressList -Identity <GlobalAddressListIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

Identity = The Identity parameter specifies a unique identifier of the GAL being updated. These unique identifiers include the common name (CN), GUID, or distinguished name (DN).
