Chapter 15. Changing the LDAP and LDAPS port numbers

download PDF

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

Important

Other services must not use new ports that you assigned to the protocols for an instance.

15.1. Changing the port numbers using the command line

You can change the port numbers of the LDAP and LDAPS protocol using the command line. LDAP and LDAPs port change requires update of the nsslapd-port and nsslapd-securePort parameters.

Procedure

  1. Optionally: Display the current port numbers for the instance:

    # dsconf -D "cn=Directory Manager" ldap://server.example.com config get nsslapd-port nsslapd-securePort
  2. Change the LDAP port:

    1. Set the new port for the LDAP protocol. For example, to set it to 1389, run:

      # dsconf -D "cn=Directory Manager" ldap://server.example.com config replace nsslapd-port=1389
    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
  3. Change the LDAPS port:

    1. Set the new port for the LDAPS protocol. For example, to set it to 1636, run:

      # dsconf -D "cn=Directory Manager" ldap://server.example.com config replace nsslapd-securePort=1636
    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
  4. Restart the instance:

    # dsctl instance_name restart

Verification

  1. Verify that Directory Server now uses the new LDAP port by the command:

    # dsconf instance_name config get nsslapd-port
  2. Verify that Directory Server now uses the new LDAPS port number by the command:

    # dsconf instance_name config get nsslapd-securePort

15.2. Changing the port numbers using the web console

You can change the port numbers of the LDAP and LDAPS protocol using the web console.

Prerequisites

  • You are logged in to the instance in the web console.

Procedure

  1. Change the LDAP port:

    1. Open the Server Setting menu.
    2. On the Server Setting tab, enter the new port number into the LDAP Port field.
  2. Click Save.
  3. Change the LDAPS port:

    1. Open the Server Setting menu.
    2. On the General Settings tab, enter the new port number into the LDAPS Port field.
    3. Click Save.
  4. Restart the instance by clicking Action and selecting Restart Instance.

Verification

  1. Verify in the server setting that the changed port is reflected .
