Active Directory query troubleshooting

My cust开发者_如何转开发omer uses the below query to pull the data from Active Directory into my application.

CN=WebCalAdmin,OU=Security Groups,OU=Groups,DC=hasm,DC=com

and getting the below error.

Error: Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

I need to replicate the same issue in my lab environment. I have created OU's in my test active directory. But I am not sure how to create CN=WebcalAdmin in my test active directory.

Is CN and OU are same? What is the difference between CN and OU? What are the steps to create CN=WebCalAdmin in my Active Directory?

Thanks in Advance, Siva.S.

CN stands for common name and is used to identify users, groups and computers in your LDAP string.

OU stands for organizational unit and is used to identify OU's that acts as containers inside which other objects can live - e.g. the divisions, departments, etc. of your organization used to create a hierarchy and a structure.

So these two are totally different - OU's are used to build up a tree of nested containers for objects like users, groups, computers.

OU is created through AD Users and Computers tool - by clicking on New->Organization Unit and a CN node is created by doing New->User or New->Computer as needed.

If you are using softerra LDAP Admin tool then you need to do New Entry on the node and select the user/computer or your own custom schema class to proceed. You can also do this using ldif import command : ldifde.

CN is the leaf entry and can only have another CN under it. So you can have a CN under OU but not other way round.
