Querying and updating active directory using c
Specifically if you want to write a flexible program to write users in and out of different OUs, rather than a single OU, then it will be necessary to create multiple LDAP connections with different paths, and also a more complex function to add users to groups which searches the whole subtree.Duncan Mackenzie Microsoft Developer Network November 1, 2002 Summary: Duncan Mackenzie describes how to use the System.This is a much more realistic example as it’s obviously bad practise to query more data than is required.Having covered querying the AD we will now move on to updating the AD!This can be used either without setting any options or by providing a root Directory Entry object.When creating a Directory Entry object for use as a root, you will need to specify a path that describes the service you are connecting to. Creating this single object establishes a connection to your directory.If you work in the kind of large institution that I do and are using Microsoft Active Directory then the chances are that at certain times you will need to perform actions on the directory that are outside the scope of the MSAD tools.This could be things like specialised queries, bulk account creation or mass updates of user information.
So, this page contains a few basic but fully working programs which illustrate common scenarios that you may have.Directory Services—as will any ADSI paths or property names shown in an ADSI sample. Directory Services namespace will accept native ADSI objects as parameters. Directory Services namespace, Directory Entry and Directory Searcher.It is also possible to mix code between the COM and . Of course, even if you have never used ADSI, System. (Several additional classes exist, but these are the ones you need to use first.) Searching is performed using the aptly named Directory Searcher class.The properties have generic objects associated with them as the class has no concept of their content.If you wish you will need to cast or convert to more specific classes in order to perform some operations, for example a telephone extension could be cast to an This example is almost identical to the above example, however we are now selective about which fields from the AD we want to bring in.
