Hi!
The Direcroty Manager account (the one whose DN is specified in
dse.ldif as nsslapd-rootdn) is a dangerously privileged account.
Access control does not apply to this user and compromising its DN and
password gives full control over the directory server.
Therefore, it would be desirable to limit this user's bind access
based on some additional criteria, in addition to the knowledge of the
password.
Limits based on the source host (e.g. localhost) and time of day (e.g.
only work hours) would be very useful.
Is there a way to limit Directory Manager binds based on those
criteria in Fedora Directory Server?
No. But please file a bug so we can track
this issue.
Note that in OpenLDAP this is possible using the following ACL:
access to dn.base="cn=Manager,o=Example"
by peername.regex=127\.0\.0\.1 auth
by users none
by anonymous none
This ACL however requires creating a concrete LDAP entry that
corresponds to rootdn, setting a userPassword in taht entry, and
leaving the rootpw in OpenLDAP configuration undefined.
This way the concrete userPassword is used when binding and is subject
to that ACL which only allows access from connections that origin from
127.0.0.1.
