class SDM::Client

Client bundles all the services together and initializes them.

Attributes

_test_options[R]

account_attachments[R]

AccountAttachments assign an account to a role.

account_grants[R]

AccountGrants assign a resource directly to an account, giving the account the permission to connect to that resource.

accounts[R]

Accounts are users that have access to strongDM. There are two types of accounts:

**Regular users:** humans who are authenticated through username and password or SSO
**Service users:** machines that are authneticated using a service token

api_access_key[R]

API authentication token (read-only).

base_retry_delay[R]

max_retries[R]

max_retry_delay[R]

nodes[R]

Nodes make up the strongDM network, and allow your users to connect securely to your resources. There are two types of nodes:

*Relay:* creates connectivity to your datasources, while maintaining the egress-only nature of your firewall
*Gateways:* a relay that also listens for connections from strongDM clients

resources[R]

role_attachments[R]

RoleAttachments represent relationships between composite roles and the roles that make up those composite roles. When a composite role is attached to another role, the permissions granted to members of the composite role are augmented to include the permissions granted to members of the attached role.

role_grants[R]

RoleGrants represent relationships between composite roles and the roles that make up those composite roles. When a composite role is attached to another role, the permissions granted to members of the composite role are augmented to include the permissions granted to members of the attached role.

roles[R]

Roles are tools for controlling user access to resources. Each Role holds a list of resources which they grant access to. Composite roles are a special type of Role which have no resource associations of their own, but instead grant access to the combined resources associated with a set of child roles. Each user can be a member of one Role or composite role.
