.SYNOPSIS Searches LDAP server in given search root and using given search filter .OUTPUTS Search results as custom objects with requested properties as strings or byte stream .EXAMPLE Find-LdapObject -LdapConnection [string]::Empty -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"cn=Users,dc=myDomain,dc=com" Description ----------- This command connects to domain controller of caller's domain on port 389 and performs the search .EXAMPLE $Ldap = Get-LdapConnection Find-LdapObject -LdapConnection $Ldap -SearchFilter:"(&(cn=jsmith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"ou=Users,dc=myDomain,dc=com" -PropertiesToLoad:@("sAMAccountName","objectSid") -BinaryProperties:@("objectSid") Description ----------- This command connects to to domain controller of caller's domain and performs the search, returning value of objectSid attribute as byte stream .EXAMPLE $Ldap = Get-LdapConnection -LdapServer:mydc.mydomain.com -EncryptionType:SSL Find-LdapObject -LdapConnection $Ldap -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"ou=Users,dc=myDomain,dc=com" Description ----------- This command connects to given LDAP server and performs the search via SSL .EXAMPLE $Ldap = Get-LdapConnection -LdapServer "mydc.mydomain.com" Find-LdapObject -LdapConnection:$Ldap -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"cn=Users,dc=myDomain,dc=com" Find-LdapObject -LdapConnection:$Ldap -SearchFilter:"(&(cn=myComputer)(objectClass=computer)(objectCategory=organizationalPerson))" -SearchBase:"ou=Computers,dc=myDomain,dc=com" -PropertiesToLoad:@("cn","managedBy") Description ----------- This command creates the LDAP connection object and passes it as parameter. Connection remains open and ready for reuse in subsequent searches .EXAMPLE $Ldap = Get-LdapConnection -LdapServer "mydc.mydomain.com" Find-LdapObject -LdapConnection:$Ldap -SearchFilter:"(&(cn=SEC_*)(objectClass=group)(objectCategory=group))" -SearchBase:"cn=Groups,dc=myDomain,dc=com" | ` Find-LdapObject -LdapConnection:$Ldap -ASQ:"member" -SearchScope:"Base" -SearchFilter:"(&(objectClass=user)(objectCategory=organizationalPerson))" -propertiesToLoad:@("sAMAccountName","givenName","sn") | ` Select-Object * -Unique Description ----------- This one-liner lists sAMAccountName, first and last name, and DN of all users who are members of at least one group whose name starts with "SEC_" string .EXAMPLE $cred=new-object System.Net.NetworkCredential("myUserName","MyPassword","MyDomain") $Ldap = Get-LdapConnection -Credential $cred Find-LdapObject -LdapConnection $Ldap -SearchFilter:"(&(cn=myComputer)(objectClass=computer)(objectCategory=organizationalPerson))" -SearchBase:"ou=Computers,dc=myDomain,dc=com" -PropertiesToLoad:@("cn","managedBy") -RangeSize 0 Description ----------- This command creates explicit credential and uses it to authenticate LDAP query. Then command retrieves data without ranged attribute value retrieval. .EXAMPLE $Users = Find-LdapObject -LdapConnection (Get-LdapConnection) -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"cn=Users,dc=myDomain,dc=com" -AdditionalProperties:@("Result") foreach($user in $Users) { try { #do some processing $user.Result="OK" } catch { #report processing error $user.Result=$_.Exception.Message } } #report users with results of processing for each of them $Users Description ----------- This command connects to domain controller of caller's domain on port 389 and performs the search. For each user found, it also defines 'Result' property on returned object. Property is later used to store result of processing on user account .EXAMPLE $Ldap = Get-LdapConnection -LdapServer:ldap.mycorp.com -AuthType:Anonymous Find-LdapObject -LdapConnection $ldap -SearchFilter:"(&(sn=smith)(objectClass=user)(objectCategory=organizationalPerson))" -SearchBase:"ou=People,ou=mycorp,o=world" Description ----------- This command connects to given LDAP server and performs the search anonymously. .LINK More about System.DirectoryServices.Protocols: http://msdn.microsoft.com/en-us/library/bb332056.aspx #> Function Find-LdapObject { Param ( [parameter(Mandatory = $true)] [System.DirectoryServices.Protocols.LdapConnection] #existing LDAPConnection object retrieved with cmdlet Get-LdapConnection #When we perform many searches, it is more effective to use the same conbnection rather than create new connection for each search request. $LdapConnection, [parameter(Mandatory = $true)] [String] #Search filter in LDAP syntax $searchFilter, [parameter(Mandatory = $false, ValueFromPipeline=$true)] [Object] #DN of container where to search $searchBase, [parameter(Mandatory = $false)] [System.DirectoryServices.Protocols.SearchScope] #Search scope #Default: Subtree $searchScope='Subtree', [parameter(Mandatory = $false)] [String[]] #List of properties we want to return for objects we find. #Default: empty array, meaning no properties are returned $PropertiesToLoad=@(), [parameter(Mandatory = $false)] [String] #Name of attribute for ASQ search.

Notice the newName parameter - it's the same as old name as we do not rename the object a new name is required parameter for protocol. .LINK More about System.DirectoryServices.Protocols: http://msdn.microsoft.com/en-us/library/bb332056.aspx #> Function Rename-LdapObject { Param ( [parameter(Mandatory = $true, ValueFromPipeline=$true)] [Object] #Either string containing distinguishedName #Or object with DistinguishedName property $Object, [parameter(Mandatory = $true)] [System.DirectoryServices.Protocols.LdapConnection] #Existing LDAPConnection object. $LdapConnection, [parameter(Mandatory = $true)] #New name of object [String] $NewName, [parameter(Mandatory = $false)] #DN of new parent [String] $NewParent, #whether to delete original RDN [Switch] $DeleteOldRdn, [parameter(Mandatory = $false)] [System.DirectoryServices.Protocols.DirectoryControl[]] #Additional controls that caller may need to add to request $AdditionalControls=@() ) Process { [System.DirectoryServices.Protocols.ModifyDNRequest]$rqModDN=new-object System.DirectoryServices.Protocols.ModifyDNRequest switch($Object.GetType().Name) { "String" { $rqModDN.DistinguishedName=$Object } default { if($Object.distinguishedName) { $rqModDN.DistinguishedName=$Object.distinguishedName } else { throw (new-object System.ArgumentException("DistinguishedName must be passed")) } } } $rqModDn.NewName = $NewName if(-not [string]::IsNullOrEmpty($NewParent)) {$rqModDN.NewParentDistinguishedName = $NewParent} $rqModDN.DeleteOldRdn = ($DeleteOldRdn) $LdapConnection.SendRequest($rqModDN) -as [System.DirectoryServices.Protocols.ModifyDNResponse] | Out-Null } } #Helpers Add-Type @' public static class Flattener { public static System.Object FlattenArray(System.Object[] arr) { if(arr==null) return null; int i=arr.Length; if(i==0) return null; if(i==1) return arr[0]; return arr; } } '@ $referencedAssemblies=@() if($PSVersionTable.PSEdition -eq 'Core') {$referencedAssemblies+='System.Security.Principal.Windows'} Add-Type @' public class NamingContext { public System.Security.Principal.SecurityIdentifier SID {get; set;} public System.Guid GUID {get; set;} public string distinguishedName {get; set;} public override string ToString() {return distinguishedName;} public static NamingContext Parse(string ctxDef) { NamingContext retVal = new NamingContext(); var parts = ctxDef.Split(';'); if(parts.Length == 1) { retVal.distinguishedName = parts[0]; } else { foreach(string part in parts) { if(part.StartsWith("<GUID=")) { retVal.GUID=System.Guid.Parse(part.Substring(6,part.Length-7)); continue; } if(part.StartsWith("<SID=")) { retVal.SID=new System.Security.Principal.SecurityIdentifier(part.Substring(5,part.Length-6)); continue; } retVal.distinguishedName=part; } } return retVal; } } '@ -ReferencedAssemblies $referencedAssemblies |
