如何在Powershell中使用AdsiSearcher查询安全策略？

Question

I am trying to find all servers that set TrustedForDelegation : True , I am able to find all servers using ([adsisearcher]"ObjectCategory=Computer").Findall().properties but I can't see any of the security policy properties. How would I go about viewing filtering for security policy properties?

Btw the reason I am using AdsiSearcher is because I don't have the Active Directory module available to import.

The Trusted for Delegation permission is stored in the userAccountControl attribute in AD, which is a bit field , meaning that the value indicates several flags that can be on or off. The full list is here .

Adding this to your query is a little tricky. It requires a bitwise AND comparison to see if a specific flag is turned on. AD allows this through a matching rule OID called LDAP_MATCHING_RULE_BIT_AND .

You would use it in an LDAP query like this:

(userAccountControl:1.2.840.113556.1.4.803:=524288)

So your code to find all computers with the Trusted for Delegation permissions would look something like this:

([adsisearcher]"(&(objectCategory=computer)(userAccountControl:1.2.840.113556.1.4.803:=524288))").Findall()
