Currently attributes in pcache attrsets must be defined. As far as I recall this was introduced to catch misconfigurations (e.g. a typo would have silently resulted in erroneous caching). However, one may wish to cache attrs whose schema is not known. I've modified pcache to allow undef:attrname in attrsets, so the administrator needs to know what he's doing. The "undef:" is stripped during parsing, but slapd will not complain and the administrator.

I think this is a mistake. Anything slapd handles must have a defined schema. Probably the recent patches for back-ldap to support undefined filters are also a mistake. We have already documented that schema must be provided in order to get proper functioning of e.g. back-ldap. There is no reason to relax this requirement since one can always obtain the relevant schema from the target server.
