Re: Meta Idassert-bind
*** Before acting on this email or opening any attachment you are advised to read the disclaimer at the end of this email ***
I have moved local users into a seperate branch of the local DIT, set
idassert-authzFrom to this branch and set the 'non-prescriptive' flag on
With this config, remote users can bind correctly to a target. If
another target is in the scope of the query, openldap will attempt to
bind with no credentials. This behaviour is fine.
If the root user binds to the local database, openldap will use bind to
all targets in scope with the full idassert credentials.
If a local user (but not root) binds to the local database, openldap
uses the idassert dn to bind, but does not supply a password. This is
now the problem, as most of my targets require a successful bind in
order to perform queries.

If I get your wishes correctly, you should work at the
idassert-authzFrom level to only enable identity assertion for local
users, disabling it for remote users. You may need to set
"non-prescriptive" in order to allow non-authorized users to connect
