Users reported that they weren't getting all apis listed in cloudmonkey when running a sync. After some debugging, I found that the problem is that the ApiDiscoveryService is calling ApiRateLimitServiceImpl.checkAccess(), so the results of the listApis command are being truncated because Cloudstack believes the user has exceeded their API throttling rate.
I enabled throttling with a 25 request per second limit. I then created a test role with only list* permissions and assigned it to a test user. When this user calls listApis, they will typically receive anywhere from 15-18 results. Checking the logs, you see The given user has reached his/her account api limit, please retry after 218 ms..
I raised the limit to 200 requests per second, restarted the management server and tried again. This time I got 143 results and no log messages about the user being throttled.
CloudStack SSO (using security.singlesignon.key) does not work anymore with CloudStack 4.11, since commit 9988c26, which introduced a regression due to a refactoring: every API request that is not "validated" generates the same error (401 - Unauthorized) and invalidates the session.
However, CloudStack UI executes a call to listConfigurations in method bypassLoginCheck. A non-admin user does not have the permissions to execute this request, which causes an error 401:
{"listconfigurationsresponse":{"uuidList":[],"errorcode":401,"errortext":"unable to verify user credentials and/or request signature"}}
The session (already created by SSO) is then invalidated and the user cannot access to CloudStack UI (error "Session Expired").
Before 9988c26 (up to CloudStack 4.10), an error 432 was returned (and ignored):
{"errorresponse":{"uuidList":[],"errorcode":432,"cserrorcode":9999,"errortext":"The user is not allowed to request the API command or the API command does not exist"}}
Even if the call to listConfigurations was removed, another call to listIdps also lead to an error 401 for user accounts if the SAML plugin is not enabled.
This pull request aims to fix the SSO issue, by restoring errors 432 (instead of 401 + invalidate session) for commands not available. However, if an API command is explicitly denied using ACLs or if the session key is incorrect, it still generates an error 401 and invalidates the session.
Remove maven standard module (which only a few were using) and get ride of maven customization for the projects structure.
- moved all directories to src/main/java, src/main/resources, src/main/scripts, src/test/java, src/test/resources
- grep scan to search for src/com and src/org left over
- grep for <project>/scripts to fix pom.xml configuration
- remove custom <build> configuration in pom.xml

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.

https://cwiki.apache.org/confluence/display/CLOUDSTACK/Dynamic+Role+Based+API+Access+Checker+for+CloudStack
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
