Howto Almost Everything In Active Directory via CTable of Contents.When it comes to programmatically accessing Microsofts Active Directory a lot of people seem to have quite a difficult time tying all the pieces together to accomplish exactly what they want to.There are so many technologies available for communicating with LDAP that many programmers end up with a mix between COM ADSI calls and.NET class calls mixed into their code.ADSI code is so difficult to understand and follow that the creator of that code usually owns it for the entirety of its lifecycle since no one else wants to support it.This article attempts to tie together the most commonly used elements involved in Active Directory Management in the simplest, most clean manner possible.I interact with Active Directory in nearly all of my applications web forms and I have had to solve a lot of integration issues for many customers.When I was starting out with this technology I had a lot of growing pains so this is an attempt to help those programmers who may have a need to interact with the Directory but do not want to have to become experts in the issue.However, certain rudimentary knowledge and concepts are required in order to utilize the code.You must be familiar with such terms as distinguished.Hi, Im using a VB script which does the following 1.Queries an SQL DB for selected information 2.Queries LDAP for selected information 3.Writes both. Getting and Setting File Attributes Declare Function SetFileAttributes Lib kernel32 Alias SetFileAttributesA ByVal lpFileName As String, ByVal.Name, ldap paths, fully qualified domain names, object attributes single string multi string, and general knowledge of ldap schemas.There is a great collection of sample code available on MSDNs website for the v.System. Directory.Services assembly but there seems to be a void when it comes to the new functionality available in the v.System. Directory.Services. Active.Active-Directory-5-Object-permissions.png' alt='Update Active Directory Attributes Vb Script Function' title='Update Active Directory Attributes Vb Script Function' />Directory assembly.Since this articles original publishing, Generics have gained widespread acceptance and I encourage anyone borrowing from this resource to replace the archaic Array.VB. Net Quick Guide Learn VB.Net Programming in simple and easy steps starting from Environment setup, Basic Syntax, Data Types, Type Conversion, Variables.CodeGuru is where developers can come to share ideas, articles, questions, answers, tips, tricks, comments, downloads, and so much more related to programming in.List collections with Listlt T or appropriate generic collections.In order to communicate with Active Directory one must take into account network security, business rules, and technological constraints.If youre using Active Directory code from an ASP.NET page you must ensure that the code has the appropriate level of permission to access and interact with the directory.For development purposes or proof of concept you can enable impersonation at the ASP.NET level in web.IIS level and if the IIS server and the directory domain controller reside on the same machine this will work.However, if these entities are not co located on the same server as they never are in production you can wrap the code around an impersonation class such as the Zeta Impersonator which will execute the Directory calls under the token of the impersonated user.Its strongly recommended that you do not do this for security reasons unless absolutely necessary.The authorized method for granting the ASP.NET application permission to the directory is by way of either a privileged IIS Application Pool running under the identity of a service account or by way of a COM entity running under the identity of a service account.If you plan on running this code from a desktop assembly then youre going to want to ensure that your machine is attached to a domain and can communicate with that domain.The impersonation is not necessary if the user running the code has sufficient privileges on the domain.It is also important to note that if you plan on running this code from an ASP. How To Install Oracle Jre Ubuntu . NET page in batch, ASP.NET will time out on you if you try to run batch processes from its primary thread.There are several things to consider in this scenario but be aware that for example, if youre creating x number of accounts through an ASP.NET application or performing any batch operation in general that you must plan to use queues, a back end scheduler, or some other mechanism outside the scope of the page itself to prevent timing out during your processes.As with any ASPNET design, its never a good idea to use ASPNET itself for anything but the View part of the solution.The best architecture would queue tasks into a SQL database or something to that effect and then a back end windows service or similar application would pick up the tasking and perform the actual Directory operations.This is typically how I engineer Active Directory management solutions for customers.You will notice that most of the methods require the same parameters.Rather than identify each time I will outline them now friendly.Domain.

Controller.Name. Or. Ip. Address as well as everywhere you see a Directory.Entry class being constructed you can send in specific credentials as well.This is especially helpful if you need to work on an Active Directory for which your machine is not a member of its forest or domain or you want to target a DC to make the changes to.Renamestring server.Name, string password, string object.Dn, string new.

In addition to managing local directory services accounts, the versatile Directory.Entry object can manage other network providers as well, such as IIS.Below is an example of how you can use Directory.Entry to provision a new virtual directory in IIS.Inetpubwwwroot.
