RBAC in IAG

Role-based authorization and access

This article provides information on role-based access control (RBAC) for Itential Automation Gateway (IAG), which entails configuration of roles and groups for users of IAG. In the context of IAG, a role enables user access to a single route or multiple routes. They are auto-generated at the time of server initialization using information provided for each route found in the IAG API documentation. The name of a role is derived using the tag name (i.e., modules, playbooks, nornir, terraform, etc.) defined for a set of routes along with the action categories read, write, exec, and history. Note that multiple routes can fall under a given action category.

Action categories

These categories specify the actions that the role allows to be performed.

ActionDescription
readUser has access to read API calls.
writeUser has access to write API calls.
execUser has access to execute API calls.
historyUser has access to execution history API calls.

Sample role names

The following provides a sample list of role names.

  • modules:read
  • playbooks:write
  • terraform:exec
  • nornir:history

Along with roles, RBAC groups contain a set of users. Users that are members of a particular group will have access to the routes defined by the roles that have been configured for the group. Users and roles can be members of multiple groups.

The RBAC group admin is automatically created by the IAG server upon the first boot up of a release with RBAC support. When doing an upgrade from a previous release that does not contain RBAC support, all existing users will automatically be added to the admin group upon first boot up of the server. The admin group contains all roles that are made available by the server. Users that are members of the admin group have access to all available routes.

Manage users and groups in IAG

Add LDAP users and groups

For LDAP users to appear in the Itential Automation Gateway Authorization Users list, you will need to:

  • Manually create each LDAP user; make sure the username matches the LDAP username.
  • Manually create the groups in IAG to which the LDAP users will be added.

Groups are added as members to a role, and group members are listed as user members for the role. Therefore, once you have created the LDAP users and LDAP groups manually in IAG, and assigned all necessary permissions to each group, whenever an LDAP user of the same matching username logs in, that user is automatically added to the group to which the user is a member and whatever role permissions are assigned to the group.
