Hmm. LDAP_NO_ATTRS was an addition to the patch discussed here:
https://www.postgresql.org/message-id/7fcac549-0051-34c8-0d62-63b921029f20%402ndquadrant.com
Googling around I see some indications that the macro may not be
defined in all implementations and that some other projects test if
it's defined:
https://github.com/spinn3r/squid-deb/blob/master/squid-2.7.STABLE9/helpers/basic_auth/LDAP/squid_ldap_auth.c#L160
It looks like that's OK because it's required to have the value "1.1":
https://tools.ietf.org/html/rfc4511
3. A list containing only the OID "1.1" indicates that no attributes are to be returned. If "1.1" is
providedwith other attributeSelector values, the "1.1" attributeSelector is ignored. This OID was chosen
becauseit does not (and can not) correspond to any attribute in use.
It seems like we need to do that.
