Below are Microsoft TechNet Wiki pages I have published. They deal with Active Directory, LDAP, PowerShell, scripting, or the TechNet Wiki itself.

Wiki Articles About Active Directory Domain Services

Wiki: Active Directory Domain Services (AD DS) Portal
Links to articles in the TechNet Wiki dealing with Active Directory Domain Services.

Active Directory: Glossary
Glossary of terms and acronyms used in Active Directory Domain Services and related technologies.

Active Directory: Characters to Escape
Documents characters that must be escaped in Active Directory and how to handle these characters in VBScript, PowerShell, ADSI, and command line utilities like dsquery.

Active Directory: LDAP Syntax Filters
Documentation and examples of LDAP syntax filters used to query Active Directory.

Active Directory: Requirements For Creating Objects
Documentation of requirements for creating various classes of objects in Active Directory. This article can be used to troubleshoot problems creating objects.

Active Directory: Duplicate Object Name Resolution
Objects in Active Directory must have unique Relative Distinguished Names (RDN) in their organizational unit or container and unique sAMAccountName (if they are security objects). This article explains how duplicate objects can be created in Active Directory and how the system handles the situations. Describes how to detect and correct these situations.

Active Directory: Attributes in the Partial Attribute Set
Documentation of Active Directory attributes in the Partial Attribute Set (PAS), the subset of attributes that is replicated to the Global Catalog. Documents which attributes are in the PAS by default and how to add other attributes.

Active Directory: Ambiguous Name Resolution
Explanation of the Ambiguous Name Resolution (ANR) feature available with the LDAP filter syntax in Active Directory. This allows you to query for objects by name without knowing which naming attributes the name appears in. Also describes how to determine which attributes are in the ANR set and how to add attributes to the set.

Active Directory: Leading Spaces in Names
Quirks that occur when names in Active Directory have leading spaces. How to find instances of this and how to deal with the situation.

Active Directory: Generalized-Time Attributes
Documentation of Active Directory attributes that represent dates using the Generalized-Time syntax. Describes how to filter with these attributes.

Active Directory: Large Integer Attributes
Documentation of Active Directory attributes that represent dates using the Large Integer syntax. These can be large numbers, dates, or time spans. Documents the values allowed, how to script retrieval of these attribute values, and the equivalent properties exposed by the Active Directory module cmdlets.

Active Directory: Fun with Maximum Password Age
Interesting features of the Active Directory maxPwdAge attribute and the related PowerShell MaxPasswordAge property. For example, explains what happens if you assign zero to the MaxPasswordAge property using the Set-ADDefaultDomainPasswordPolicy cmdlet.

Active Directory: Non-Linked Multi-Valued Attribute Size Limits
Active Directory limits the total number of values summed across all non-linked multi-valued attributes of any object. The error is "The administrative limit for this request was exceeded". There are no limits on linked multi-valued attributes.

Active Directory: Allow Linked Multi-Valued Attributes to use LVR
If values were added to linked multi-valued attributes before the Forest Functional Level (FFL) was raised to at least Windows Server 2003, the attribute will not be able to take advantage of linked value replication (LVR). These are called "Legacy" values. Without LVR, the replication of these attributes will be much less efficient.

Active Directory: Bad Passwords and Account Lockout
Not all logon attempts with a bad password count against the account lockout threshold. Passwords that match one of the two most recent passwords in password history will not increment the badPwdCount. Nor will they update the badPasswordTime attribute of the user. Because the lockoutObservationWindow attribute is the amount of time since the badPasswordTime was last updated, this affects how quickly badPwdCount is reset.

Active Directory: Find Orphaned Objects
This article describes a PowerShell script to find all orphaned objects in Active Directory. The script also documents all security principals protected by SDProp.

Wiki Articles About PowerShell and Active Directory

Document Your Active Directory Organization
Describes a PowerShell script in the Microsoft TechNet Gallery to document your Active Directory organization, based on the manager and directReports attributes.

PowerShell Script to Search Active Directory
Describes a PowerShell script in the Microsoft TechNet Gallery to search for information in Active Directory. The script can be used to retrieve information from Active Directory and to test various LDAP syntax filters.

Filters with PowerShell Active Directory Module Cmdlets
Documentation for LDAP and PowerShell syntax filters that can be used with the Active Directory module cmdlets, like Get-ADUser. These filters are used with the -LDAPFilter and -Filter parameters of the cmdlets.

Active Directory: PowerShell AD Module Properties
Documentation of Default, Extended, and Base properties exposed by the PowerShell Active Directory module cmdlets. Explains how these properties differ from the actual Active Directory attributes.

Active Directory: Get-ADUser Default and Extended Properties
Documents the Default and Extended properties exposed by the Get-ADUser cmdlet.

Active Directory: Get-ADComputer Default and Extended Properties
Documents the Default and Extended properties exposed by the Get-ADComputer cmdlet.

Active Directory: Get-ADGroup Default and Extended Properties
Documents the Default and Extended properties exposed by the Get-ADGroup cmdlet.

Active Directory: Get-ADObject Default and Extended Properties
Documents the Default and Extended properties exposed by the Get-ADObject cmdlet.

Active Directory: Get-ADOrganizationalUnit Default and Extended Properties
Documents the Default and Extended properties exposed by the Get-ADOrganizationalUnit cmdlet.

Active Directory: Get-ADServiceAccount Default and Extended Properties
Documents the Default and Extended properties exposed by the Get-ADServiceAccount cmdlet.

Active Directory: Get-ADOptionalFeature Default and Extended Properties
Documents the Default and Extended properties exposed by the Get-ADOptionalFeature cmdlet.

Active Directory: Get-ADFineGrainedPasswordPolicy Default and Extended Properties
Documents the Default and Extended properties exposed by the Get-ADFineGrainedPasswordPolicy cmdlet.

PowerShell AD Module Cmdlets Cannot Clear, Add, Remove or Replace Back Link Attributes
Several of the PowerShell Active Directory module cmdlets accept the -Clear, -Add, -Remove, and -Replace parameters. However, these parameters raise an error if you attempt to use them to modify a back link attribute. For example, you cannot use Set-ADUser to clear the memberOf attribute of a user.

PowerShell: Problems with the -ne Operator in Active Directory Cmdlets
This article describes an issue with the PowerShell "not equal to" operator, -ne, when used with the Active Directory module cmdlets. When used with the -Filter parameter you get incomplete results. The cmdlet does not return objects where the Active Directory attribute or PowerShell property has no value.
