* * * * * The ZMS client utility allows administrators to manage Athenz domains, to check domain details, create personal domains, and add other administrators. Download latest ZMS Client utility binary release from : click on the `Browse` button, choose the latest version directory and then download the `athenz-utils-<latest-version>-bin.tar.gz`. ```shell $ tar xvfz athenz-utils-X.Y-bin.tar.gz ``` Before you can use the ZMS client utility, you need to have asked the Athenz administrators to create your top level domain. The help argument for the utility will display all commands available through utility. $ zms-cli help To get additional details about a specific command: $ zms-cli help [command] For example, to get complete details on how to add a domain including examples: $ zms-cli help add-domain Use the `-z` option to point to the required environment for executing commands. $ zms-cli -z https://zms-server.athenzcompany.com:4443/zms/v1 -d athenz show-domain -- The Athenz ZMS server requires the user to provide its `UserToken` or use a User certificate and private key for MTLS to authenticate with ZMS (depending on the Principal Authority used). ZMS will then authorize the request based on the configured authority. To find out what domains have been provisioned in Athenz, run the following: $ zms-cli list-domain The list-domain command also takes an optional prefix argument to filter the domains and only return those that start with the specified string. For example, if the user wants to list only the domains that have been configured in the `athenz` product domain, he/she will run the following command: $ zms-cli list-domain athenz domains: athenz athenz.ci athenz.qa To view the full list of administrators for a given domain, run the following: $ zms-cli -d <domain-name> show-role admin For example, to view the Athenz system administrators for the domain `media.news`: $ zms-cli -d media.news show-role admin -- The Top Level Product Domains in ZMS are provisioned by Athenz administrators. Once the Product Domain has been created, the designated domain administrators can create any subdomains as necessary. To create a new domain, the administrator uses the `add-domain` command: $ zms-cli add-domain <product sub domain> [<admin1> <admin2> ...] <domain> The name of the domain to be added, which could either be a product domain or a subdomain. For example, to add a subdomain called `storage` in the `athenz` domain, the value for `<domain>` would be `athenz.storage`. The parent domain must exist before a subdomain can be created. The domain name can only include any letters, digits and the '-' character. The maximum length of the domain name (including all subdomain parts) is 256 bytes. [<admin1> ...] A space-separated list of administrators for the domain. The user creating the domain is automatically added as an

If user `joe` executes the command below, the product domain `coretech` is created and will include `user.joe` as an administrator: $ zms-cli add-domain coretech When user `joe` executes the command below, the sub domain `athenz.ci` is created and will have the administrators `yby.joe`, `yby.john`, and `yby.jane`: $ zms-cli add-domain athenz.ci yby.john yby.jane ZMS supports Personal Domains. These domains are provisioned for users in the User `user` domain and have the same functionality as Product Domains in Athenz. The Personal Domain uses the syntax `user.<user-id>` and can have configured number of subdomains (default 2). For example, if your user ID is joe and you'd like to create a Personal Domain, you would run the following command: $ zms-cli add-domain user.joe Then, to create a subdomain called `athenz-test` in your Personal Domain, you would run the following command: $ zms-cli add-domain user.joe.athenz-test If the user wants to list only his/her personal domains that have been registered, he/she will run the following command: $ zms-cli list-domain user.<user-id> Domain administrators are the principals listed as members of the role `admin`. When you create a domain, the role and corresponding policy `role` are created. Administrators can manage the list of current domain administrators by adding or removing members in the `admin` role. To add one or more administrators: $ zms-cli -d <domain> add-member admin <user1> [<user2> ...] To remove existing domain administrators: $ zms-cli -d <domain> delete-member admin <user1> [<user2> ...] ZMS allows you to remove yourself from the `admin` role. Once you've been removed, you'll need to ask another domain administrator to re-add you to the `admin` role. To add new regular role to a domain, the administrator will execute the following zms-cli command: $ zms-cli -d <domain> add-regular-role <role> <member> [<member> ...] <h3 id="parameters-1">Parameters</h3> <domain> The name of the domain that the new role belongs to. <role> The name of the new role to be added. <member> [<member> ...] A space-separated list of members for the role. At least one member must be specified. If the member is a regular user, then user's id must be prefixed with `user.`. Once the group has been created, the administrator can add and/or delete members using the `add-member` and `delete-member` commands. When the domain administrator executes the command below, a new role called `readers` will be added to the the domain `athenz.ci` will have the following members: user - `user.john` and service - `media.sports.storage`: $ zms-cli -d athenz.ci add-regular-role readers user.john media.sports.storage -- To add and/or delete members to/from a given role in a domain, the administrator will execute the following zms-cli commands: $ zms-cli -d <domain> add-member <role> <member> [<member> ...] $ zms-cli -d <domain> delete-member <role> <member> [<member> ...] <h3 id="parameters-2">Parameters</h3> <domain> The name of the domain that the role belongs to. <role> The name of the role that will be modified to add or remove

<member> [<member> ...] A space-separated list of members to be added to the role or to be removed from the role. At least one member must be specified. If the member is a regular user, the user's id must be prefixed with `user.`. When specifying service identities as members you must provide the full service name in then &lt;domain-name&gt;.&lt;service-name&gt; format. <h3 id="example-1">Example</h3> To add two new members: service "media.sports.storage" and user "yby.john", to a role called "readers" in the domain "athenz", the domain administrator will execute the following command: $ zms-cli -d athenz add-member readers yby.john media.sports.storage To delete member "media.sports.storage" from a role called "writers" in the domain "athenz", the domain administrator will execute the following command: $ zms-cli -d athenz delete-member writers media.sports.storage To add a temporary member to a given role in a domain, the administrator will execute the following zms-cli commands: ``` $ zms-cli -d <domain> add-temporary-member <role> <member> <expiration> ``` <h3 id="parameters-3">Parameters</h3> ``` <domain> ``` The name of the domain that the role belongs to. ``` <role> ``` The name of the role that will be modified to add. ``` <member> ``` A member to be added to the role. Only one member must be specified. If the member is a regular user, the user's short id must be prefixed with `user.`. ``` <expiration> ``` Expiration date. It is expected to be in UTC timezone in the form of `YYYY-MM-DDTHH:MM:SSZ` - for example: 2017-03-02T15:04:00Z <h3 id="example-2">Example</h3> To add a new member: user `user.john`, to a role called `readers` in the domain `sports.nhl`, with expiration date set to 1PM UTC time on Sep. 3rd, 2018, the domain administrator will execute the following command: ``` $ zms-cli -d sports.nhl add-temporary-member readers user.john 2018-09-03T13:00:00Z ``` To add new policy to a domain, the administrator will execute the following zms-cli command: $ zms-cli -d <domain> add-policy <policy> [<assertion>] <h3 id="parameters-4">Parameters</h3> <domain> The name of the domain that the new policy belongs to. <policy> The name of the new policy to be added. [<assertion>] where <assertion> is '<effect> <action> to <role> on <resource>' The value effect must be either 'grant' or 'deny'. The action is the domain administrator defined action available for the resource (e.g. read, write, delete). The role is the name of the role this assertion applies to. The resource is the name of the resource this assertion applies to. Once the policy has been created, the administrator can add and/or delete assertions using the `add-assertion` and `delete-assertion` commands. <h3 id="example-3">Example</h3> When the domain administrator executes the command below, a new policy called `writers` will be added to the the domain `athenz.ci` that will grant `write` access to all the members of the `sports_writers` role on `articles.sports.*`: $ zms-cli -d athenz.ci add-policy writers grant write to sports_writers on 'articles.sports.*'
