Security services

A security service stores configuration information for clients 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 from 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.

The security service can be added to the share network <shared_file_systems_share_networks>.

To create a security service, specify the security service type and optionally name, description of a security service, DNS IP address used inside tenant's network, security service IP address or host name, domain, security service user or group used by tenant, a password of user.

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> that is not used yet (is not associated with a share).

Add a security service to the share network with share-network-security-service-add specifying share network, security service and print the information about the security service. You can see new attribute share_networks with 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 given share network. List security services for share_net2 share network:

$ manila share-network-security-service-list share_net2

+--------------------------------------+--------------------------+--------+------+
| id                                   | name                     | status | type |

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

You also can dissociate a security service from the share network and see that a security service now has 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

Shared File Systems service allows you to update a security service fields using manila security-service-update command with optional arguments such as --dns-ip, --server, --domain, --user, --password, --name, or --description.

To remove a security service, that is not associated with any share networks, run:

$ manila security-service-delete my_ldap_security_service
