1.9. Changing the LDAP and LDAPS Port Numbers

By default, Directory Server uses port 389 for the LDAP and, if enabled, port 636 for the LDAPS protocol. You can change these port numbers, for example, to run multiple Directory Server instances on one host.

Important

The new ports you assign to the protocols for an instance must not be in use by any other service.

1.9.1. Changing the Port Numbers Using the Command Line

To change the port numbers using the command line, update the following parameters:
  • nsslapd-port: Stores the port number the instance uses for the LDAP protocol.
  • nsslapd-secureport: Stores the port number the instance uses for the LDAPS protocol.
To change the port numbers of the LDAP and LDAPS protocol using the command line:
  1. Optionally, display the currently configured port numbers for the instance: 
    # dsconf -D "cn=Directory Manager" ldap://server.example.com config get nsslapd-port nsslapd-secureport
nsslapd-port: 389
nsslapd-secureport: 636
    Copy to Clipboard Toggle word wrap
  2. To change the LDAP port:
    1. Set the port for the LDAP protocol. For example, to set it to 1389: 
      # dsconf -D "cn=Directory Manager" ldap://server.example.com config replace nsslapd-port=1389
Successfully replaced "nsslapd-port"
      Copy to Clipboard Toggle word wrap
    2. Set the ldap_port_t type for the LDAP port you assigned in the previous step: 
      # semanage port -a -t ldap_port_t -p tcp 1389
      Copy to Clipboard Toggle word wrap
  3. To change the LDAPS port:
    1. Set the port for the LDAPS protocol. For example, to set it to 1636: 
      # dsconf -D "cn=Directory Manager" ldap://server.example.com config replace nsslapd-secureport=1636
Successfully replaced "nsslapd-secureport"
      Copy to Clipboard Toggle word wrap
    2. Set the ldap_port_t type for the LDAPS port you assigned in the previous step: 
      # semanage port -a -t ldap_port_t -p tcp 1636
      Copy to Clipboard Toggle word wrap
  4. Restart the instance: 
    # dsctl instance_name restart
    Copy to Clipboard Toggle word wrap

1.9.2. Changing the Port Numbers Using the Web Console

To change the port numbers of the LDAP and LDAPS protocol using the web console:
  1. Open the Directory Server user interface in the web console. See Section 1.4, “Logging Into Directory Server Using the Web Console”.
  2. Select the instance.
  3. To change the LDAP port:
    1. Open the Server Settings menu.
    2. On the Server Settings tab, fill the new port number into the LDAP Port field.
    3. Click Save.
  4. To change the LDAPS port:
    1. Open the Server Settings menu.
    2. On the General Settings tab, fill the new port number into the LDAPS Port field.
    3. Click Save.
  5. Restart the instance. See Section 1.5.2, “Starting and Stopping a Directory Server Instance Using the Web Console”.
