[389-devel] Trying to understand entryrdn.db

Hello, I would like some help in order to understand entryrdn.db. When I do "dbscan -f entryrdn.db" I get something like: 3 ID: 3; RDN: "ou=Groups"; NRDN: "ou=groups" C3 ID: 6; RDN: "cn=Accounting Managers"; NRDN: "cn=accounting managers" P6 ID: 3; RDN: "ou=Groups"; NRDN: "ou=groups" I understand that 3 is this entry's ID, C3 means child of entry 3 and P6 means parent of entry 6. What I don't understand however is why those entries are repeated again and again. For example " ID: 7; RDN: "cn=HR Managers"; NRDN: "cn=hr managers" is repeated about a dozen of times in my entryrdn. And I don't mean like a parent, child, or whatever. It is repeated lots of time as ID 7 for example (but also many times as C3, etc.). I attach the complete output of what I get when I run "dbscan -f entryrdn.db", in order to demonstrate what I mean (my db contains almost default entries only). So my question is; how is this database filled? Thank you very much, Ilias
