Administrative

You can choose how the users logging into the Nexus Dashboard GUI are authenticated. This release supports local authentication as well as LDAP, RADIUS, and TACACS remote authentication servers. User roles and permissions are described in this section, remote authentication configuration is described in Remote Authentication, and local user configuration is described in Users.

Roles and Permissions

Cisco Nexus Dashboard allows user access according to roles defined by role-based access control (RBAC). Roles are used in both local and external authentication and apply to either the Nexus Dashboard, the services running in it, or both. All roles can be assigned with read-only or write privileges. Read-only access allows the user to view objects and configurations, while write access allows them to make changes.

The following sections describes the user roles available in Nexus Dashboard and their associated permissions within the platform as well as the individual services.

Nexus Dashboard and Orchestrator Roles

User Role ND Platform Orchestrator Service

Administrator

Provides full access to all settings, features, and tasks.

The only role that allows adding and removing services.

Full access.

Approver

note.gif

Note blank.gif The domain must already exist before you can set it as the default domain. Adding remote authentication domains is described in Remote Authentication.

  1. Navigate to your Nexus Dashboard’s Admin Console.

  2. Choose the default login domain.

    503618.jpg

    1. From the main navigation menu, select Administrative > Authentication.

    2. In top right of the Default Authentication tile, click the Edit icon.

      The Default Authentication window opens.

  3. In the Default Authentication that opens, choose the Login Domain from the dropdown.

Remote Authentication

Cisco Nexus Dashboard supports a number of remote authentication providers, including LDAP, TACACS, and Radius.

When configuring external authentication servers:

  • You must configure each user on the remote authentication servers.

  • All LDAP configurations are case sensitive.

    For example, if you have OU=Cisco Users on the LDAP server and OU=cisco users on the Nexus Dashboard, the authentication will not work.

  • For LDAP configurations, we recommend using CiscoAVPair as the attribute string. If, for any reason, you are unable to use an Object ID 1.3.6.1.4.1.9.22.1, an additional Object IDs 1.3.6.1.4.1.9.2742.1-5 can also be used in the LDAP server.

    Alternatively, instead of configuring the Cisco AVPair values for each user, you can create LDAP group maps in the Nexus Dashboard.

  • Single sign-on (SSO) between the Nexus Dashboard, sites, and applications is available for remote users only.

  • When using SSO to cross-launch into an APIC site from your Nexus Dashboard’s Sites page, the AV pairs defined for the Nexus Dashboard user are also used when logging into the APIC.

    For example, a user defined as admin for the Nexus Dashboard cluster will also have admin privileges in the APIC.

Configuring Remote Authentication Server

When configuring the remote authentication server for the Nexus Dashboard users, you must add a custom attribute-value (AV) pair, specifying the username and the roles assigned to them.

The user roles and their permissions are the same as for the local users you would configure directly in the Nexus Dashboard GUI as described in Roles and Permissions.

The following tables list the Nexus Dashboard user roles and the AV pair you would use to define the roles on a remote authentication server, such as LDAP.

The AV pair string format differs when configuring a read-write role, read-only role, or a combination of read-write and read-only roles for a specific user. A typical string includes the domain, followed by the read-write roles separated from the read-only roles using the slash (/) character; individual roles are separated by the pipe (|) character:

shell:domains=<domain>/<writeRole1>|<writeRole2>/<readRole1>|<readRole2>

For example, the following string illustrates how to assign the Tenant Manager and Policy Manager roles to a user, while still allowing them to see objects visible to the User Manager users:

shell:domains=all/tenant-policy|site-policy/aaa

Note that if you want to configure only the read-only or only read-write permissions for a user, you must still include the slash (/) character. The following examples show how to set just the read-write or read-only access to the objects available to Site Administrator role:

  • Read-only: shell:domains=all//site-admin

  • Read-write: shell:domains=all/site-admin/

Adding LDAP as Remote Authentication Provider

Before you begin

  • You must have at least one user already configured on the LDAP server as described in Configuring Remote Authentication Server.

    You will need to use an existing user for end-to-end verification of LDAP configuration settings.

To add an LDAP remote authentication provider:

  1. Navigate to your Nexus Dashboard’s Admin Console.

  2. Add an authentication domain.

    503619.jpg

    1. From the main navigation menu, select Administrative > Authentication.

    2. In top right of the main pane, click the Actions menu and select Create Login Domain.

  3. In the Create Login Domain screen that opens, provide domain details.

    1. Provide the Name for the domain.

    2. (Optional) Provide its Description.

    3. From the Realm dropdown, select Ldap.

    4. Then click +Add Provider to add a remote authentication server.

      The Add Provider window opens.

  4. Provide the remote authentication server details.

    2. (Optional) Provide the Description of the server.

    3. Provide the Port number.

      The default port is 389 for LDAP.

    4. Provide the Base DN and Bind DN.

      The Base DN and Bind DN depend on how your LDAP server is configured. You can get the Base DN and Bind DN values from the distinguished name of the user created on the LDAP server.

      Base DN is the point from which the server will search for users. For example, DC=nd,DC=local.

      Bind DN is the credentials used to authenticate against the server. For example, CN=admin, CN=Users,DC=nd,DC=local.

    5. Provide and confirm the Key.

      This is the password for your Bind DN user. Anonymous bind is not supported, so you must provide a valid value in these fields.

    6. Specify the Timeout and number of Retries for connecting to the authentication server.

    7. Provide the LDAP Attribute field for determining group membership and roles.

      The following two options are supported:

      • ciscoAVPair (default) — used for LDAP servers configured with Cisco AVPair attributes for user roles.

      • memberOf — used for LDAP servers configured with LDAP group maps. Adding a group map is described in a following step.

    8. (Optional) Enable SSL for LDAP communication.

      If you enable SSL, you must also provide the SSL Certificate and the SSL Certificate Validation type:

      • Permissive: Accept a certificate signed by any certificate authority (CA) and use it for encryption.

      • Strict: Verify the entire certificate chain before using it.

    9. (Optional) Enable Server Monitoring.

      If you choose to enable monitoring, you must also provide the Username and Password for it.

    10. In the Validation fields, provide a Username and Password of a user already configured on the LDAP server you are adding.

      Nexus Dashboard will use this user to verify the end-to-end authentication to ensure that the settings you provided are valid.

    11. Click Save to complete provider configuration.

    12. Repeat this step for any additional LDAP authentication servers you want to use with this domain.

  5. (Optional) Enable and configure LDAP Group Map Rules.

    If you want to authenticate your LDAP users using Cisco AV pair strings, skip this step.

    1. In the LDAP Auth Choice, select LDAP Group Map Rules.

    2. Click Add LDAP Group Map Rule.

      The Add LDAP Group Map Rule window opens.

    3. Provide the Group DN for the group.

    4. Select one or more Roles for the group.

    5. Click Save to save the group configuration.

    6. Repeat this step for any additional LDAP groups.

  6. Click Create to finish adding the domain.

The Administrative > Security Configuration page allows you to configure authentication session timeouts and security certificates used by your Nexus Dashboard cluster.

Before you begin

  • You must have the keys and certificates you plan to use with Nexus Dashboard already generated.

    Typically, this includes the following files:

    • Private key (nd.key)

    • Certificate Authority’s (CA) public certificate (ca.crt)

    • CA-signed certificate (nd.crt)

    Generating these files for self-signed certificates is described in Generating Private Key and Self-Signed Certificate.

  • We recommend creating a configuration backup of your Nexus Dashboard cluster before making changes to the security configurations.

    For more information about backups, see [Backup and Restore].

To edit security configuration:

  1. Navigate to your Nexus Dashboard’s Admin Console.

  2. Edit security configuration.

    1. From the main navigation menu, select Administrative > Security.

    2. In the main pane, select the Security Configuration tab.

    3. In top right of the main pane, click the Edit icon.

  3. In the Security Configuration screen that opens, update the details as required:

    Note that uploading the keys and certificate files is not supported and you will need to paste the information in the following fields.

    1. Update the Session Timeout.

      This field defines the duration of the API tokens with the default duration set to 20 minutes.

    2. Update the Idle Timeout.

      This field defines the duration of the UI session.

    3. In the Domain Name field, provide your domain.

    4. In the Key field, provide your private key.

    5. In the RSA Certificate field, provide the CA-signed or self-signed certificate.

    6. In the Root Certificate field, provide the CA’s public certificate.

    7. (Optional) If your CA provided an Intermediate Certificate, provide it in the Intermediate Certificate field.

    8. Click Save to save the changes.

      After you save your changes, the GUI will reload using the new settings.

Security Domains

A restricted security domain allows an administrator to prevent a group of users from viewing or modifying any objects created by a group of users in a different security domain, even when users in both groups have the same assigned privileges.

For example, an administrator in restricted security domain (domain1) will not be able to see sites, services, cluster or user configurations in another security domain (domain2).

Note that a user will always have read-only visibility to system-created configurations for which the user has proper privileges. A user in a restricted security domain can be given a broad level of privileges within that domain without the concern that the user could inadvertently affect another group’s physical environment.

To create a security domain:

  1. Navigate to your Nexus Dashboard’s Admin Console.

  2. Create a new security domain.

    1. From the main navigation menu, select Administrative > Security.

    2. In the main pane, select the Security Domains tab.

    3. In top right of the main pane, click Create Security Domain.

  3. In the Create Security Domain screen that opens, provide the domain details.

    1. Provide the Name for the domain.

    2. (Optional) Provide a description for the domain.

    3. Click Create to save the domain.
