The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Testing Windows user account for group membership

Asked by c0dejunkie in Lightweight Directory Access Protocol (LDAP), Visual Basic Programming, Active Directory

Tags: ,

I am attempting to add basic ActiveDirectory integration into a Visual Basic 6 (VB6) desktop application. I have found a number of methods to obtaining information from ActiveDirectory, however none have been able to successfully answer the simple question; "Is 'currentuser' a member of 'desiredgroup'?" Some of the solutions I have found so far have come close, allowing me to iterate through the ActiveDirectory objects, however this approach does not resolve multi-tier membership, e.g. User1 is a member of MyGroup which is a member of SuperGroup which is a member of DesiredGroup.

The closest I have come is with something akin to the following, using the ADO OLE DB connector and LDAP_MATCHING_RULE_IN_CHAIN, but I can't figure out the correct filter syntax to state I want any record for User1 where DesiredGroup is somewhere in the membership tree:

cmdRead.CommandText = "<LDAP://LocalHost>;(memberOf:1.2.840.113556.1.4.1941:=CN=User1);ADsPath, cn; base"

 --or maybe--

cmdRead.CommandText = "<WinNT://MyComputer>;(memberOf:1.2.840.113556.1.4.1941:=CN=DesiredGroup);ADsPath, cn; base"

Alternatively, the other solution path I have been working with is using the interfaces provided via ActiveDS.dll to connect with GetObject("WinNT://" & strComputer & "") and parse through the objects.

If anyone has some tips or helper routines that can help me get past this learning curve and achieve the function I am working toward with either of these solution trees, or some other that I have not come across yet, it would be much appreciated.Start Free Trial
