Excludes those with no description field at all
All groups with a name of ‘Professional Services Department’ and a description of ‘Live’.'cn -eq "Professional Services Department"' or ` '(cn=Professional Services Department)' All groups with a name (cn) of ‘Professional Services Department’.Here are some examples using active directory group filters you can use as a base to begin creating your own. LDAP Filter Examplesīuilding LDAP filters can be challenging. Property values for comparison do not normally need to be wrapped in quotes. The LDAP filter rules must be used with the LDAP names of attributes, and certain character values must be ‘escaped’ if used in an LDAP filter. LDAP filters also have a special matching rule Object IDentifiers (OIDs): OIDĬhain matching (for distinguished name attributes) Filter rules can be grouped by surrounding the group in parentheses and including a comparator from the following: Operator Įach filter rule is surrounded by parentheses ( ). The syntax for LDAP filters is defined in RFC number 4515. Using the LDAPFilter parameter with the cmdlets allows you to use LDAP filters, such as those created in Active Directory Users and Computers. Read on to learn how LDAP Filters assist in filtering that data! LDAP FiltersĪctive Directory implements LDAP, the Lightweight Directory Access Protocol. Many different object types are stored and made accessible by Active Directory with the LDAP protocol functioning as a means to access that data.Īs Active Directory can store many different data types, applications and users need a way to query that directory easily. You may think of a phonebook when hearing the word directory, but in the context of Active Directory, this means so much more. LDAP, or Lightweight Directory Access Protocol, is a vendor-neutral protocol for accessing and modifying directory data. You should use -like and -notlike operators for wildcard comparison. Only required if the data is enclosed in single quotes.Īutomatically escaped. Only required if the data is enclosed in double quotes. You can see above that the filter is surrounded by double quotes yet Adam Bertram is surrounded with single quotes.Ĭertain characters must be ‘escaped’ when used in filters. The only wildcard accepted is the asterisk ( *). Property values are normally wrapped in single or double quotes. Property names can be the name or LDAP filter name of the property returned with the AD cmdlet. PS51> Get-Aduser -Filter "Name -eq 'Adam Bertram'" If you’d like to find all users matching a specific name, you’d use: For example, the Get-AdUser cmdlet returns a Name property. Inside of the filter, you will compare various AD object properties using operators. Inside of the Filter parameter, you can use the following operators. The operators used here are the familiar operators you may be used to when using commands like Where-Object. While building a filter for the Filter parameter, you’ll need to use at least one operator. These filters are used with the the Filter parameter. This is commonly referred to as Active Directory search filter syntax. PowerShell filters use the standard PowerShell expression syntax. There are two different filter languages you can use when searching for objects using many of the Active Directory cmdlets: PowerShell filters and LDAP filters. you can successfully connect and authenticate to an AD domain controller.you have the PowerShell ActiveDirectory module installed.
