As this is the first database, the controls also apply to entries not held in any
|
|
database (such as the Root DSE). For all applicable entries, the userPassword
|
|
attribute is writable by the entry itself and by the "admin" entry. It may be used for
|
|
authentication/authorization purposes, but is otherwise not readable. All other attributes
|
|
are writable by the entry and the "admin" entry, but may be read by all users (authenticated or not).</P
|

><P
|
|
>The next section of the example configuration file defines another BDB database.
|
|
This one handles queries involving the dc=example,dc=net subtree but is managed by the same
|
|
entity as the first database. Note that without line 39, the read access would be allowed due
|
|
to the global access rule at line 4.</P
