Found DAG object in Active Directory

Dear Friends,
Today i have detected an Object called 'DAG' in Active Directory. I am not aware of these objects. Please some one could elaborate? It might be a silly question. But still i am feeling free to learn.
Regards, Jay.

Hi,
This object is the Cluster Name Object(CNO) for a DAG.
In Exchange 2010 when using the Database Availability Group (DAG), we leverage the cluster services in Windows 2008 and Windows 2008 R2. This requires that a machine account be created within the directory for association with this cluster name resource.
This is known as the CNO or cluster name object.
For more information about CNO, you can refer to the following article.
Exchange 2010 – Pre-staging the Cluster Name Object (CNO) to support a Database Availability Group (DAG)

OBIEE+ Problems trying to import objects from Active Directory

Hi
I'm trying to import my users from my Active Directory using the Administration Tool.
If I give the Base DN to point to the Users entry and I get that It doesn't have any objects to import.
If I give the Base DN to point to the parent folder of Users and Groups entry I get
LDAP server referral not supported.
Any configurations that I have to take in consideration?

Henrik,
I've found other problems where OWB adds a space between all characters returned from SQL*Server which is what is happening in your case, although it is being displayed as a square box.
In one of these cases the problem was fixed by using the 11.2.0.2 OWB so would it be possible for you to try with that version ?
Also, as the problem is not with the gateway itself as you can select successfully using a database link then it would be better to follow up in the OWB forum -
Forum: Warehouse Builder
Warehouse Builder
as they will be able to help with the OWB side of the problem.

Mike

Active Directory Domain Services crash after Administrator renames object in Active Directory Users and Computers

Hello.
We have two domain controllers - node1 (Windows 2008 R2) and node2 (Windows 2012 R2). When administrator connects to node2 and tries to rename some object in AD (for example, user) AD Domain Services crashes and reboot server after 60 seconds.
In Events I can see these messages:

Hi Azamat Hackimov,
Regarding to error messages, it seems that the
ntdsai.dll file caused the issue. Based on current situation, please use
sfc /scannow command to scan protected system files and check if find error and repair. Meanwhile, you can also navigate to the location of this DLL file and confirm details.
In addition, Windows Server 2012 R2 has reboot unexpectedly. Please check if you get some dump file and then analysis it. It may help us to find the root reason. Please refer
to the following KB.

Size limitation for all attributes in user objects in Active Directory????

hi geeks , i wanna know maximum size limit of an user objects attribute in   active directory ... like max amount of character first name attribute can hold ... Thank in advance..

You can use ADSI Edit to view the properties of the attributes in the Schema container of your AD. In the Schema container you can select an attribute, like Company, right click, select properties, and find the rangeUpper property of the attribute. This
is the maximum length in characters (or bytes). You can also use dsquery to retrieve rangeUpper for an attribute. For example:
dsquery * "cn=Schema,cn=Configuration,dc=MyDomain,dc=com" -filter "(LDAPDisplayName=streetAddress)" -attr rangeUpper
where your domain is MyDomain.com. This finds the maximum length for the "street address" attribute. A few values in my test domain (the values can be modified, so these are the defaults):
company                      64
streetAddress              1024
physicalDeliveryOfficeName  128
initials                      6
st                          128
postOfficeBox                40
name                        255
cn                           64
You can use the first two spreadsheets on this page to help identify attributes in AD (with no Exchange):
http://www.rlmueller.net/UserAttributes.htm
The first spreadsheet documents the attributes corresponding to the fields on most of the tabs of ADUC. For example, "st" is the attribute for state, "physicalDeliveryOfficeName" for the field labeled "office". You need the
LDAPDisplayName's of the attributes, like I used in the dsquery command above. The second spreadsheet documents all attributes in AD with more information, like the syntax and which class each applies to.

Logoncount Attribute on Computer objects in Active Directory

Hello,
I have one question about the logoncount Attribute on Active Directory objects. As I understood on user objects this attribute counts the number of logons per DC (because it is not replicating).
My question is:
What exactly is count here on computer objects?
I can see that on a Domain Controller computer object the logoncount is high for the DC itself and low on the other DC objects.
Thank you.
Regards
Dennis

Here is an old thread. You will see some of the explanation from our own Richard :)

Hide all except one object in Active Directory Users and Computers.

Hello,
I have a question.. I need to allow to one group of "administrators" creating users in one OU and adding computers to the domain, nothing else. I allowed them to log on DC using the GPO "Allow log on locally", because I don't want to give
them administrator rights, I allowed them to do these operations on one OU through delegation wizard and now I need to make all OUs, groups etc. invisible to them except this OU. What is the best way how to achieve this? Thank you...
d.

I would disable the ability to allow them to login. I suggest to create a Computers OU that you can delegate to the "admins" to add computers, and don't use the default Computers container.
I assume the admins are using Windows 7 or newer. You can customize an RSAT installation to just provide the ADAC.

Or if you want to chop it down and control it further, create a custom ADUC with just that OU you've delegated. I've done this in the past and worked fine for my customer:

Removing Exchange 2007 from SBS 2008 (In an Exchange 2010 Coexistance Scenario) - In order to remove 2007 Mailbox Objects from Active Directory and remove the SBS2008 server completely

I'm trying to remove Exchange 2007 from an SBS 2008 server
(Server 2008 Standard FE). My ultimate goal is to completely remove the SBS 2008 Server from the network environment.
We have an Exchange 2010 Coexistence Scenario and Mailboxes/Public Folders/etc have been moved over to the 2010 mail server, on Server 2008 R2.
I have moved all Shares, FSMO roles, DHCP, DNS, etc over to their respective servers. We have two full blown DC's in the environment.
I'm ready to remove Exchange 2007 from SBS 2008 and DCPROMO the server. I can NOT seem to find a TechNet article that shows me how
to proceed in this kind of scenario. I am trying to use the TechNet article:
http://technet.microsoft.com/en-us/library/dd728003(v=ws.10).aspx
This article references Disabling Mailboxes, Removing OAB, Removing Public Folder Databases, then uninstalling Exchange using the Setup Wizard.
When I go to Disable Mailboxes I get the following error:
Microsoft Exchange Error
Action 'Disable' could not be performed on object 'Username (edited)'.
Username (edited)
Failed
Error:
Object cannot be saved because its ExchangeVersion property is 0.10 (14.0.100.0), which is not supported by the current version 0.1 (8.0.535.0). You will need a later version of Exchange.
OK
I really don't see why I need to Disable Mailboxes, Remove OAB and Public Folder Databases since they have been moved to 2010. I just want
to remove Exchange 2007 and DCPROMO this server (actually I just want to remove any lingering Exchange AD Objects referring to the SBS 2008 Server, using the easiest and cleanest method possible).
Can someone point me in the right direction?
Thanks!

Hi,
Based on your description, it seems that you are in a migration process (migrate SBS 2008 to Windows Server
2008 R2). Now, you want to remove Exchange Server and demote server. If anything I misunderstand, please don’t hesitate to let me know.
On current situation, please refer to following articles and check if can help you.

Action Object and Active Directory?

Hi,
As I understand the documentation, there is no way to use Action Object in Storage Manager for AD.
Is that correct?
Is it possible to work around that when having IDM implemented?
Many of our customers uses provisioning and self-provisioning through the UA-portal, and it seems rather difficult to integrate this to the NTFS in AD using Storage Manager.
When customers is running OES and NSS it is a lot easier to customize and maintain a useful dynamic file system.
Does anyone has any ideas or experience that could help us out?
Thank you in advance

Exchange 2010 - #554 5.2.0 The Active Directory user wasn't found

We have migrated form Exchange 2003 to Exchange 2010 a year ago with no issues. All Exchange legacy servers uninstalled with no issues. We had an issue today were emails sent to mail-enabled public folder was returning NDRs. This happened on two or three

Active Directory - Lingering Objects

Hello,
I'm having an issue with replication and I'm hoping someone can point me in the right direction.
I have the Strict Replication setting enabled on all of my DCs. I am running into a problem with replication failures due to lingering objects. I ran repldiag.exe /removelingeringobjects /advisorymode on one of the DCs and it found 52 objects.
However, the lingering objects are shared printer objects that are still in use in my organization. What would be the impact of deleting these printer objects? Would my workstations loose the ability to print to these printers?
Thank you.

Have you reviewed the link below?

[Forum FAQ] Using PowerShell to assign permissions on Active Directory objects

As we all know, the
ActiveDirectoryAccessRule class is used to represent an access control entry (ACE) in the discretionary access control list (DACL) of an Active Directory Domain Services object.
To set the permissions on Active Directory objects, the relevant classes and their enumerations are listed as below:
System.DirectoryServices.ActiveDirectoryAccessRule class:
http://msdn.microsoft.com/en-us/library/system.directoryservices.activedirectoryaccessrule(v=vs.110).aspx
System.DirectoryServices.ActiveDirectoryRights
class:
http://msdn.microsoft.com/en-us/library/system.directoryservices.activedirectoryrights(v=vs.110).aspx
System.Security.AccessControl.AccessControlType class:
http://msdn.microsoft.com/en-us/library/w4ds5h86(v=vs.110).aspx
System.DirectoryServices.ActiveDirectorySecurityInheritance class:
http://msdn.microsoft.com/en-us/library/system.directoryservices.activedirectorysecurityinheritance(v=vs.110).aspx
In this article, we introduce three ways to get and set the ACE on an Active Directory object. In general,
we use Active Directory Service Interfaces (ADSI) or
Active Directory module cmdlets
with the Get-Acl and Set-Acl cmdlets to assign simple permissions on Active Directory objects. In addition, we can use the extended rights and GUID settings to execute
more complex permission settings.
Method 1: Using ADSI
1. Get current permissions of an organization unit (OU)
We can use the PowerShell script below to get current permissions of an organization unit and you just need to define the name of the OU.
$Name = "OU=xxx,DC=com"
$ADObject = [ADSI]"LDAP://$Name"
$aclObject = $ADObject.psbase.ObjectSecurity
$aclList = $aclObject.GetAccessRules($true,$true,[System.Security.Principal.SecurityIdentifier])
$output=@()
foreach($acl in $aclList)
$objSID = New-Object System.Security.Principal.SecurityIdentifier($acl.IdentityReference)
     $info = @{
'ActiveDirectoryRights' = $acl.ActiveDirectoryRights;
'InheritanceType' = $acl.InheritanceType;
'ObjectType' = $acl.ObjectType;
'InheritedObjectType' = $acl.InheritedObjectType;
'ObjectFlags' = $acl.ObjectFlags;
'AccessControlType' = $acl.AccessControlType;
'IdentityReference' = $acl.IdentityReference;
'NTAccount' = $objSID.Translate( [System.Security.Principal.NTAccount] );
'IsInherited' = $acl.IsInherited;
'InheritanceFlags' = $acl.InheritanceFlags;
'PropagationFlags' = $acl.PropagationFlags;
$obj = New-Object -TypeName PSObject -Property $info
$output+=$obj}
$output
In the figure below, you can see the results of running the script above:
Figure 1．
2. Assign a computer object with Full Control permission on an OU
We can use the script below to delegate Full Control permission to the computer objects within an OU:
$SysManObj = [ADSI]("LDAP://OU=test….,DC=com") #get the OU object
$computer = get-adcomputer "COMPUTERNAME" #get the computer object which will be assigned with Full Control permission within an OU
$sid = [System.Security.Principal.SecurityIdentifier] $computer.SID
$identity = [System.Security.Principal.IdentityReference] $SID
$adRights = [System.DirectoryServices.ActiveDirectoryRights] "GenericAll"
$type = [System.Security.AccessControl.AccessControlType] "Allow"
$inheritanceType = [System.DirectoryServices.ActiveDirectorySecurityInheritance] "All"
$ACE = New-Object System.DirectoryServices.ActiveDirectoryAccessRule $identity,$adRights,$type,$inheritanceType #set permission
$SysManObj.psbase.ObjectSecurity.AddAccessRule($ACE)
$SysManObj.psbase.commitchanges()
After running the script above, you can check the computer object in Active Directory Users and Computers (ADUC) and it is under the Security tab in OU Properties.
Method 2: Using Active Directory module with the Get-Acl and Set-Acl cmdlets
You can use the script below to get and assign Full Control permission to a computer object on an OU:
$acl = get-acl "ad:OU=xxx,DC=com"
$acl.access #to get access right of the OU
$computer = get-adcomputer "COMPUTERNAME"
$sid = [System.Security.Principal.SecurityIdentifier] $computer.SID
# Create a new access control entry to allow access to the OU
$identity = [System.Security.Principal.IdentityReference] $SID
$adRights = [System.DirectoryServices.ActiveDirectoryRights] "GenericAll"
$type = [System.Security.AccessControl.AccessControlType] "Allow"
$inheritanceType = [System.DirectoryServices.ActiveDirectorySecurityInheritance] "All"
$ACE = New-Object System.DirectoryServices.ActiveDirectoryAccessRule $identity,$adRights,$type,$inheritanceType
# Add the ACE to the ACL, then set the ACL to save the changes
$acl.AddAccessRule($ace)
Set-acl -aclobject $acl "ad:OU=xxx,DC=com"
Method 3: Using GUID setting
The scripts above can only help us to complete simple tasks, however, we may want to execute more complex permission settings. In this scenario, we can use GUID settings to achieve
that.
The specific ACEs allow an administrator to delegate Active Directory specific rights (i.e. extended rights) or read/write access to a property set (i.e. a named collection of attributes) by
setting ObjectType field in an object specific ACE to the
rightsGuid of the extended right or property set. The delegation can also be created to target child objects of a specific class by setting the
InheritedObjectType field to the schemaIDGuid of the class.
We choose to use this pattern: ActiveDirectoryAccessRule(IdentityReference, ActiveDirectoryRights, AccessControlType, Guid, ActiveDirectorySecurityInheritance, Guid)
You can use the script below to
assign the group object with the permission to change user password on all user objects within an OU.
$acl = get-acl "ad:OU=xxx,DC=com"
$group = Get-ADgroup xxx
$sid = new-object System.Security.Principal.SecurityIdentifier $group.SID
# The following object specific ACE is to grant Group permission to change user password on all user objects under OU
$objectguid = new-object Guid
00299570-246d-11d0-a768-00aa006e0529 # is the rightsGuid for the extended right User-Force-Change-Password (“Reset Password”)
class
$inheritedobjectguid = new-object Guid
bf967aba-0de6-11d0-a285-00aa003049e2 # is the schemaIDGuid for the user
$identity = [System.Security.Principal.IdentityReference] $SID
$adRights = [System.DirectoryServices.ActiveDirectoryRights] "ExtendedRight"
$type = [System.Security.AccessControl.AccessControlType]
"Allow"
$inheritanceType = [System.DirectoryServices.ActiveDirectorySecurityInheritance] "Descendents"
$ace = new-object System.DirectoryServices.ActiveDirectoryAccessRule $identity,$adRights,$type,$objectGuid,$inheritanceType,$inheritedobjectguid
$acl.AddAccessRule($ace)
Set-acl -aclobject $acl "ad:OU=xxx,DC=com"
The figure below shows the result of running the script above:
Figure 2．
In addition, if you want to assign other permissions, you can change the GUID values in the script above. The common GUID values are listed as below:
$guidChangePassword

The ActiveDirectoryAccessRule has more than one constructor, but yes, you've interpreted the one that takes six arguments correctly.
Those GUIDs are different (check just before the first dash). Creating that ACE will create an empty GUID for InheritedObjectType, though, because you're telling it to apply to the Object only ([System.DirectoryServices.ActiveDirectorySecurityInheritance]::None).
Since the ACE will only apply to the object, there's no need to worry about what types of objects will inherit it.
If you've got time, check out
this module. It will let you view the security descriptors in a much friendlier format. Try both version 3.0 and the version 4.0 preview:
Sample version 3.0:
# This is going to be kind of slow, and it will take a few seconds the first time
# you run it because it has to build the list of GUID <--> Property/Class/etc objects
Get-ADGroup GroupY |
Get-AccessControlEntry -ObjectAceType member -InheritedObjectAceType group -ActiveDirectoryRights WriteProperty
# Same as the previous command, except limit it to access granted to GroupX
Get-ADGroup GroupY |
Get-AccessControlEntry -ObjectAceType member -InheritedObjectAceType group -ActiveDirectoryRights WriteProperty -Principal GroupX
Here's version 4.0. It's way faster than 3.0, but it's missing the -ObjectAceType and -InheritedObjectAceType parameters on Get-AccessControlEntry (don't worry, when they come back they'll be better than in 3.0):
Get-ADGroup GroupY |
Get-AccessControlEntry
Get-ADGroup GroupY |
Get-AccessControlEntry -ActiveDirectoryRights WriteProperty
Get-ADGroup GroupY |
Get-AccessControlEntry -ActiveDirectoryRights WriteProperty -Principal GroupX
# You can do a Where-Object filter until the parameters are added back to Get-AccessControlEntry:
Get-ADGroup GroupY |
Get-AccessControlEntry -ActiveDirectoryRights WriteProperty |
where { $_.AccessMask -match "All Prop|member Prop" }
Get-ADGroup GroupY |
Get-AccessControlEntry -ActiveDirectoryRights WriteProperty |
where { $_.ObjectAceType -in ($null, [guid]::Empty, "bf9679c0-0de6-11d0-a285-00aa003049e2") }
Get-ADGroup GroupY |
Get-AccessControlEntry -ActiveDirectoryRights WriteProperty |
where { $_.AccessMask -match "All Prop|member Prop" -and $_.AppliesTo -match "group"}
That's just for viewing. Version 3.0 can add and remove access, or you can use New-AccessControlEntry to replace your call to New-Object, and you can still use Get-Acl and Set-Acl. The benefit to New-AccessControlEntry is that you can do something like this:
New-AccessControlEntry -Principal GroupX -ActiveDirectoryRights WriteProperty -ObjectAceType member -InheritedObjectAceType group #-AppliesTo Object

Recon and provisioning of user-defined object class ICF Active Directory

I have followed the documentation instructions for reconciliation of a user-defined object class in the ICF Active Directory connector. I am using OIM 11gR2 with the ICF Active Directory 11.1.1.5 connector patched to 11.1.1.5.0A. The procedure states to create the new object class in AD and then change the objectClass value in the Lookup.Configuration.ActiveDirectory lookup. In my case I am using the existing ObjectClass of contact, rather than a new object class. Just for completeness I am using a clone of the AD User Resource Object which I call AD User Contact and so my lookup name is Lookup.Configuration.ActiveDirCon.
When I changed the ObjectClass from User to Contact, and ran the Active DirCon User Target Recon scheduled job, with Object Type also = contact. The first issue I noticed was that the connector wanted a different set of lookups, which is not in the documentation. It is looking for a lookup in my Configuration lookup where code key=contact Configuration Lookup (which I should have expected since there are code keys for User, Group, and organizationalUnit). I added a line to the lookup where code key=contact Configuration Lookup and the Decode=Lookup.ActiveDirCon.CM.Configuration and then I created a new lookup by that name, assigning the 5 values to be the Lookup.ActiveDirCon.UM.xxx lookups. I did not see any need to create a new set of Lookup.ActiveDirCon.CM.xxx lookups with the exact same values.
I re-ran the scheduled job and it ran successfully, but did not generate any Recon Events, even though I had objects in the OU and I have that same OU in the Lookup.ActiveDirCon.OrganizationalUnits lookup (from the Org Lookup Recon). Everything looks good but getting no results. Looked at the log file from the ConnectorServer and it is building the query properly and executing it properly with the correct syntax, getting no errors, but the SearchAndReturnObjects method is returning zero results.
Looking to see if anyone has successfully reconciled in user-defined or other non-User objectClass objects from Active Directory, and if so, can you provide Lookup configuration and Connector Server information so I can troubleshoot.
I resolved this issue by changing the recon lookups to a blank lookup called Lookup.ActiveDirCon.CM.ReconAttrMap and only added in the parameters that are used by a Contact object. Only populate the ReconAttrMap with parameters that exist for the custom object.

Why do I get general access denied trying to update my own field in Active Directory?

I am trying to update a field pertaining to my own user object in Active Directory using ADSI and C++ app. The operating system
is Windows Server 2012 Standard.
I am able to read, I am able to call Put without problems, but when I call SetInfo, it returns with "General access denied". I have
confirmed that it's my own user object I'm trying to access.
I obtain my own FQDN like this:
GetUserNameEx(EXTENDED_NAME_FORMAT::NameFullyQualifiedDN, pszFullyQualifiedDN, &dwFullyQualifiedDN);
Then I use it like this:
LPTSTR pszObj = (LPTSTR)LocalAlloc(LPTR, dwMemToAlloc);
wcscpy_s(pszObj, dwMemToAlloc / sizeof(TCHAR), L"LDAP://");
wcscat_s(pszObj, dwMemToAlloc / sizeof(TCHAR), pszFullyQualifiedDN);
I bind to an object like this:
ADsGetObject(pszObj, IID_IADs, (LPVOID*)&pObject);
This call succeeds:
pObject->Get(CComBSTR("Description"), &var);
This call also succeeds:
VariantClear(&var);
V_BSTR(&var) = SysAllocString(L"Some new value");
V_VT(&var) = VT_BSTR;
hr = pObject->Put(CComBSTR("Description"), var);
Trying to commit the above change using the following:
pObject->SetInfo();
This is where it fails.
It returns E_ACCESSDENIED General access denied error.
As you can see, that is my own user object I am trying to update. To my understanding that is supposed to work provided I am a member of Domain
Users group. Which I am.
What could possibly be the problem?

The problem is that in Windows Server 2012 Domain Controller, permission to write to public (and personal,
for that matter) properties is not granted to "SELF". The field I am trying to write to belongs to public properties. The only property set a user is able to change for himself in Windows Server 2012, by default, seems to be "Private-Information",
which consists of ms-PKI-Credential-Roaming-Tokens,ms-PKI-RoamingTimeStamp, ms-PKI-DPAPIMasterKeys, ms-PKI-AccountCredentials
Why on earth a user doesn't have permission to write to his own personal fields in Windows Server 2012 AD, Microsoft??!?!?!

Creating computer Names with small letters and they appear as capitals in Active Directory Domain

Hello,
When I try to create computer objects in Active Directory - namely when i change computer name with small letters, in active directory users and computers they appear as capital letters and in DNS console as well.
I know that it's not a problematic issue and technically all goes fine but, i want to know the reason.
Is it possible to change computer name with small letters while joining in the domain and than in AD it appear with small letters also ?
Thanks in advance,

If you are asking about during the client join process, I believe the machines do all caps and you have to accept that as default. I'm guessing it is a legacy issue for older clients that has hung on such as possibly related to WINS.

What is the Point of Active Directory/LDAP Specification?

My college threw an interesting curve ball today and I couldn't give him a good enough answer. The question was simple 'What is the point of active directory'. Now I don't have a lot of exposure to active directory, but I thought I could easily answer. My argument was; If you have a group of objects its easy to look up attributes for those objects using active directory. For example, if you have a group in AD and you want to verify the users of that group you simply look up the member attribute of that group. However he argued, rightly so, that you can do that with a table in a database, why do that in AD. I couldn't give him a good enough answer and now I'm curious. Given the above example, why use AD over a database?
To me AD is a way to manage a set of resources, whatever they are, by mapping them to objects that have however many attributes. But we could do that in a database, whats the point of AD? Why do you use AD?

I come from a primarily database centric background. Just like life experience, it casts a certain perspective on problems. Database people solve things with databases. Directory people solve things with directories. Everyone has their perspective. It's not really about who's right and who's wrong. It's about perspective because people are most likely to go with what's familiar when given a problem. It's easy to have this conversation in a educational environment but when you're on the job it's about turf, schedules and careers. My latest job (in which this debate comes up a lot) has been about directories which has been a very enlightening experience because I've been given a gift of perspective. I can put on the directory hat and look at it from another angle.
To get back to your professor's question. The answer is easy. LDAP (AD or other) is an application above a database. It has a data store behind it, in most cases we can just assume this is a database. So, in short, it's apples to oranges. But if we insist on comparing which makes the better juice, let's look at how we'd make a database like a directory. We could create a data model with an attributes table, an entries table and so on. We can deconstruct what LDAP data structures really are and implement each type as a table with FK/PK relationships and so on. It's sure to work because there are already so many products on the market doing this very thing. But think about the effort now. How are you going to add new users? A front-end? Stored procedures? Scripts? How are you going to keep someone from seeing things they shouldn't? You have to insert an object into all the right tables to ensure that your data is consistent and valid. In a pure database, you're trying to create ACLs on database rows. Now you're writing a full featured application with a lot of complexity. Given enough directory features, the database isn't going to be able to do everything without an external application.
What is the point of LDAP? It's got hierarchy, ACLs, group of unique names functionality and things that are a layer of abstraction above the data store. I love databases but if you start designing out a directory server from scratch you'll realize it's far beyond comparing a user.ldif to a row in a user table. They are similar in appearance but different types of software.
