Nimble Components

Flexible authentication

By utilizing the flexible authentication options provided by the Apache Shiro project we've built in support for authentication for local accounts. In the future with some small additional plugins we will support Oauth authentication.

Fine grained access control

By combining the three core access control concepts of users, groups and roles with the permissions engine exposed by Apache Shiro your application can achieve fine grained access control across controllers, views, services, GSPs and native Java logic.

Permissions can be applied to users, roles and groups. Users can be members of an unlimited number of groups. Both users and groups are able to be assigned roles. Enabling permissions to cascade through this structure is where Nimble gains its real access control flexibility. This process is also dynamic. If you remove or apply a permission that ultimately applies to a currently active Nimble based user session that user obtains or loses access without needing to terminate their session.

Lots, LOTS more on offer

We've barely scratched the surface in this overview of what Nimble can provide to your project. We encourage you to try it out for yourself. At the moment we're still in early stages so we're working away on more tests, more documentation and example applications. Everything is fully usable now however and is already the basis of several large commercial projects currently underway.
