This feature allows root administrators to define new roles and associate API
permissions to them.
A limited form of role-based access control for the CloudStack management server
API is provided through a properties file, commands.properties, embedded in the
WAR distribution. Therefore, customizing API permissions requires unpacking the
distribution and modifying this file consistently on all servers. The old system
also does not permit the specification of additional roles.

DB-Backed Dynamic Role Based API Access Checker for CloudStack brings following
changes, features and use-cases:
- Moves the API access definitions from commands.properties to the mgmt server DB
- Allows defining custom roles (such as a read-only ROOT admin) beyond the
current set of four (4) roles
- All roles will resolve to one of the four known roles types (Admin, Resource
Admin, Domain Admin and User) which maintains this association by requiring
all new defined roles to specify a role type.
- Allows changes to roles and API permissions per role at runtime including additions or
removal of roles and/or modifications of permissions, without the need
of restarting management server(s)
Upgrade/installation notes:
- The feature will be enabled by default for new installations, existing
deployments will continue to use the older static role based api access checker
with an option to enable this feature
- During fresh installation or upgrade, the upgrade paths will add four default
roles based on the four default role types
- For ease of migration, at the time of upgrade commands.properties will be used
to add existing set of permissions to the default roles. cloud.account
will have a new role_id column which will be populated based on default roles
as well
Dynamic-roles migration tool: scripts/util/migrate-dynamicroles.py
- Allows admins to migrate to the dynamic role based checker at a future date
- Performs a harder one-way migrate and update
- Migrates rules from existing commands.properties file into db and deprecates it
- Enables an internal hidden switch to enable dynamic role based checker feature
