That appears to be the RFC 2891 described behavior (section 2,
item 4).

There is an I-D available for review:
  draft-armijo-ldap-control-error-01.txt
        
I believe the current intent is to modify VLV to use this result
code.

I would like to see this result code used with SSS as well, but
that would require revising RFC 2891.

The client should first check the LDAP resultCode in the
response PDU.  If this resultCode is controlError, then the
client should behave as indicated in the request control(s)
specifications.  This may involve checking values in response
control(s).

Note that SSS does prescribe use of controlError and hence
the processing of SSS should not result in a controlError.
