Active Directory: LDAP Syntax Filters
LDAP syntax filters can be used in many situations to query Active Directory. They can be used in VBScript and PowerShell scripts. Many utilities, like adfind and dsquery *, accept LDAP filters. Many PowerShell Active Directory module cmdlets, like Get-ADUser, Get-ADGroup, Get-ADComputer, and Get-ADObject, accept LDAP filters with the LDAPFilter parameter.
