I guess this has been asked before, but I couldn't find precious information on google (other than "don't do that"). I am trying to tidy up my custom schema definition. If I remove an attribute (and restart ldap and so on), the attribute is still visible. Well, I guess it's still in the database. Is there a possibility other than slapcat | grep | slapadd to remove these attributes from the database? ldap 2.3.30-2.

Well, you could restore the attribute in the schema, search for '(<attrname>=*)' as the rootdn, and issue a Modify operation for each returned entry which deletes the attribute. Then delete it from the schema.
