Not seen it written this way before. December 15, 2015 at 4:36 am #32959 Matt BloomfieldParticipant In LDAP syntax the comparison operator goes at the start of the clause so, in your, example. The filter translates to "give me all the objects where the operatingSystem attribute is 'windows 10' AND the object is a computer object". Lots of examples and how to use the syntax here: Active Directory LDAP Syntax Filters December 15, 2015 at 6:12 am #32967 Graham BeerParticipant Thank you Matt, very helpful. Good link as well.
