Expand description

The Kanidmd server library. This implements all of the internal components of the server which is used to process authentication, store identities and enforce access controls.

Modules§

  • The backend. This contains the “low level” storage and query code, which is implemented as a json-like kv document database. This has no rules about content of the server, which are all enforced at higher levels. The role of the backend is to persist content safely to disk, load that content, and execute queries utilising indexes in the most effective way possible.
  • Entries are the base unit of object storage in the server. This is one of the three foundational concepts along with filters and schema that everything else builds upon.
  • An event is a self contained module of data, that contains all of the required information for any operation to proceed. While there are many types of potential events, they all eventually lower to one of:
  • Filters are one of the three foundational concepts of the design in kanidm. They are used in nearly every aspect of the server to provide searching of datasets and assertion of entry properties.
  • The Identity Management components that are layered on top of the QueryServer. These allow rich and expressive events and transformations that are lowered into the correct/relevant actions in the QueryServer. Generally this is where “Identity Management” policy and code is implemented.
  • Modification expressions and validation. This is how ModifyEvents store and express the series of Modifications that should be applied. These are expressed as “states” on what attribute-values should appear as within the Entry
  • A prelude of imports that should be imported by all other Kanidm modules to help make imports cleaner.
  • Schema is one of the foundational concepts of the server. It provides a set of rules to enforce that Entries ava’s must be compliant to, to be considered valid for commit to the database. This allows us to provide requirements and structure as to what an Entry must have and may contain which enables many other parts to function.
  • server contains the query server, which is the main high level construction to coordinate queries and operations in the server.
  • An actor that shows the servers current status and statistics. (TODO).
  • Inside an entry, the key-value pairs are stored in these Value types. The components of the Value module allow storage and transformation of various types of input into strongly typed values, allows their comparison, filtering and more. It also has the code for serialising these into a form for the backend that can be persistent into the Backend.
