Get Data From Active Directory To MS SQL Server

I look for and try to get data from Active Directory to MSSQL Server, but have same error:

Msg 7321, Level 16, State 2, Line 1
An error occurred while preparing the query "SELECT name
FROM 'LDAP://office.experter.group'
WHERE objectCategory = 'Person' AND objectClass = 'user'" for execution against OLE DB provider "ADsDSOObject" for linked server "ADSI".

for the code:

select * from openquery
(
ADSI,'SELECT name
FROM ''LDAP://office.experter.group''
WHERE objectCategory = ''Person'' AND objectClass = ''user'''
)

I create linked server:

EXEC master.dbo.sp_addlinkedserver @server = N'ADSI',
@srvproduct=N'Active Directory Services', @provider=N'ADsDSOObject',
@datasrc=N'office.experter.group'

I've changed security setting, format of LDAP. Please advise me
