This module will enumerate computers in the default AD directory.
Optional Attributes to use in ATTRIBS:
objectClass, cn, description, distinguishedName, instanceType, whenCreated,
whenChanged, uSNCreated, uSNChanged, name, objectGUID,
userAccountControl, badPwdCount, codePage, countryCode,
badPasswordTime, lastLogoff, lastLogon, localPolicyFlags,
pwdLastSet, primaryGroupID, objectSid, accountExpires,
logonCount, sAMAccountName, sAMAccountType, operatingSystem,
operatingSystemVersion, operatingSystemServicePack, serverReferenceBL,
dNSHostName, rIDSetPreferences, servicePrincipalName, objectCategory,
netbootSCPBL, isCriticalSystemObject, frsComputerReferenceBL,
lastLogonTimestamp, msDS-SupportedEncryptionTypes
ActiveDirectory has a MAX_SEARCH limit of 1000 by default. Split search up
if you hit that limit.
Possible filters:
(objectClass=computer) # All Computers
(primaryGroupID=516) # All Domain Controllers
(&(objectCategory=computer)(operatingSystem=*server*)) # All Servers
