NOTE

The Admin Server supports both IPv4 and IPv6 addresses.

The Admin Server entry can be edited using ldapm odify.

To set host restrictions:

1. Get the name of the Admin Server entry. Since the Admin Server entry has a special object class,

nsAdminConfig, it is possible to search for the entry using that object class to retrieve the DN.

/usr/lib/mozldap/ldapsearch -D "cn=directory m anager" -w secret -p 389 -h

server.example.com -b "o=NetscapeRoot" "(objectclass=nsAdminConfig)" dn

version:1

dn: cn=configuration, cn=adm in-serv-example, cn=Red Hat Adm inistration

Server, cn=Server Group, cn=server.example.com, ou=example.com,

o=NetscapeRoot

2. T o set IP address-based restrictions, edit the nsAdminAccessAddresses attribute.

/usr/lib/mozldap/ldapm odify -D "cn=directory manager" -w secret -p 389 -h

server.example.com

dn: cn=configuration, cn=adm in-serv-example, cn=Red Hat Adm inistration

Server, cn=Server Group, cn=server.example.com, ou=example.com,

o=NetscapeRoot

changetype:modify

replace:nsAdminAccessAddresses

nsAdm inAccessAddresses:72.5.*.*

Hit Enter twice to submit the operation, and then Control+C to close ldapm odify.

The nsAdminAccessAddresses value can use wildcards to allow ranges. For example, to allow all

IP addresses:

nsAdm inAccessAddresses:*

To allow only a subset of addresses on a local network:

nsAdm inAccessAddresses:192.168.123.*

3. T o set hostname or domain-based restrictions, edit the nsAdminAccessHosts attribute.

/usr/lib/mozldap/ldapm odify -D "cn=directory manager" -w secret -p 389 -h

server.example.com

dn: cn=configuration, cn=adm in-serv-example, cn=Red Hat Adm inistration

Server, cn=Server Group, cn=server.example.com, ou=example.com,

o=NetscapeRoot

changetype:modify

replace:nsAdminAccessHosts

nsAdm inAccessHosts:*.example.com

Hit Enter twice to submit the operation, and then Control+C to close ldapm odify.
