[Fedora-directory-users] Limiting Directory Manager (nsslapd-rootdn) by source host (e.g. 127.0.0.1)?

[Aleksander Adamowski]

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?


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.
