pcache uses slap_bv2tmp_ad() to register undef attributes. It looks like there's a bug here in that it doesn't initialize ad->ad_index. (bv2undef initializes this to zero.) Of course, that still doesn't change the fact that back-mdb requires schema to be fully defined. > At a minimum, the documentation needs to be updated to note this feature > incompatibility.
