Re: Questions about the Monitor Backend

Hello,

I have recently upgraded from 2.3.24 to 2.4.16.
I find two points confusing in the "Monitor Backend" section
of the B annex "Upgrading from 2.3.x" in the admin guide
(http://www.openldap.org/doc/admin24/appendix-upgrading.html#Monitor%20Backend
).

First my slapd happily starts even when I have no rootdn in my
"database monitor" section.

Second the example of the admin guide reads:
        database monitor
        rootdn cn=monitor
        rootpw change_me

Is it on purpose that the rootdn equals the hadcoded suffix of the
monitor database?


Yes.


In the "Monitor" section of the admin guide, the example reads:
         database monitor
         rootdn "cn=monitoring,cn=Monitor"
         rootpw monitoring

The choice of the rootdn seems much more intuitive
Seems less intuitive to me... "root" means the base / origin / trunk / whatever. Calling something that is clearly *below* the root the "rootdn" is nonsensical. The fact that it's been standard practice for others says to me that those other folks' brains were muddled when they defined all these things. 


but then it seems
a bit weird to not use it in the ACL below:
You seem to have forgotten that the current database's rootdn always ignores all ACLs on that database. The purpose of this ACL is to allow the "uid=Admin" identity that resides in some *other* database to have privileges in this database. 


          access to dn.subtree="cn=Monitor"
               by dn.exact="uid=Admin,dc=my,dc=org" write
               by users read
               by * none
