No, it is correct as is (returning an error of too many records for
this case). See p.944:

15.4.6 SUBNADMGET() / SUBNADMGETRESP(): GET AN ATTRIBUTE

C15-0.1.30: Ine response to a SubnAdmGet(), if a single attribute would
be returned based on the access rules specified in 15.4.1 Restrictions on
Access on page 938 and the matching of components specified by the
ComponentMask, then SubAdmGetResp() shall return that attribute with
a zero status value.

C15-0.1.31: If SubnAdmGet() fails to satisfy C15-0.1.30:, SubnAdmGet-
Resp() shall return with the status field providing the reason for failure
(see Table 190 SA MAD Class-Specific Status Encodings on page 900).
