Security services

A security service stores client configuration information used for
authentication and authorization (AuthN/AuthZ). For example, a share
server will be the client for an existing service such as LDAP,
Kerberos, or Microsoft Active Directory.

You can associate a share with one to three security service
types:

  • ldap: LDAP.
  • kerberos: Kerberos.
  • active_directory: Microsoft Active Directory.

You can configure a security service with these options:

  • A DNS IP address.
  • An IP address or host name.
  • A domain.
  • A user or group name.
  • The password for the user, if you specify a user name.

You can add the security service to the share network <shared_file_systems_share_networks>.

To create a security service, specify the security service type, a
description of a security service, DNS IP address used inside project’s
network, security service IP address or host name, domain, security
service user or group used by project, and a password for the user. The
share name is optional.

Create a ldap security service:

$ manila security-service-create ldap --dns-ip 8.8.8.8 --server 10.254.0.3 --name my_ldap_security_service

To create kerberos security service, run:

$ manila security-service-create kerberos --server 10.254.0.3 --user demo --password secret --name my_kerberos_security_service --description "Kerberos security service"

To see the list of created security service use manila security-service-list:

$ manila security-service-list
+--------------------------------------+------------------------------+--------+----------+
| id                                   | name                         | status | type     |

+--------------------------------------+------------------------------+--------+----------+

You can add a security service to the existing share network <shared_file_systems_share_networks>,
which is not yet used (a share network not associated with
a share).

Add a security service to the share network with
share-network-security-service-add specifying share network
and security service. The command returns information about the security
service. You can see view new attributes and share_networks
using the associated share network ID.

$ manila share-network-security-service-add share_net2 my_ldap_security_service

$ manila security-service-show my_ldap_security_service

It is possible to see the list of security services associated with a
given share network. List security services for share_net2
share network with:

$ manila share-network-security-service-list share_net2
+--------------------------------------+--------------------------+--------+------+
| id                                   | name                     | status | type |

+--------------------------------------+--------------------------+--------+------+

You also can dissociate a security service from the share network and
confirm that the security service now has an empty list of share
networks:

$ manila share-network-security-service-remove share_net2 my_ldap_security_service

$ manila security-service-show my_ldap_security_service
+----------------+--------------------------------------+
| Property       | Value                                |
