Cannot Reference New Attribute In Active Directory

We have had an existing linked server that we used to query AD and everything was working as expected. We had to add a new attribute so the AD schema was extended.

Now when I try to reference the new field I get the following error:

Server: Msg 7399, Level 16, State 1, Line 1
OLE DB provider 'ADsDSOObject' reported an error. The provider did not give any information about the error.
OLE DB error trace [OLE/DB Provider 'ADsDSOObject' IColumnsInfo::GetColumnsInfo returned 0x80004005: The provider did not give any information about the error.].

Here is the code that gives the error:

SELECT employeeNumber as Employee_Number,
NECASupervisor
FROM OpenQuery(ADSI,
'SELECT employeeNumber,NECASupervisor
from ''LDAP://OU=NECA,OU=UserAccounts,DC=neca,DC=pri''
')

This query works fine:

SELECT employeeNumber as Employee_Number
FROM OpenQuery(ADSI,
'SELECT employeeNumber
from ''LDAP://OU=NECA,OU=UserAccounts,DC=neca,DC=pri''
')

Note: The field NECASupervisor is the new AD attribute. It is in the UserAccounts OU. If I run the same type of query using VB script it finds the attribute.

Anyone have any ideas on this?


Thanks
