Sorry, I'm such a noob at LDAP...I need to do some more reading.
I'm following David Bogen's instructions and executing the
commands from the section he gave (which is what I was trying
before as well). It looks like this:
server bin # ./ldapmodify -D "cn=directory manager" -w password
dn:
some.server.com
changetype: modify
replace: nsAdminAccessHosts nsAdminAccessAddresses
nsAdminAccessHosts:
nsAdminAccessAddresses: 224.0.0.0
That DN is incorrect.
See the top of the "How to find the Admin Server configuration entry"
part of that How-To for how to find the correct DN using ldapsearch.
