K2 blackpearl has two components for User Authentication: the Authentication Provider and the Role Provider. As their names imply, the Authentication Provider does the actual authentication, while the Role Provider resolves roles within K2 (also known as authorization).

Authentication and Role providers use Security Labels to identify specific instances of Authentication and/or Role providers.

The default Security Label in K2 blackpearl is K2. This security label is associated to the Active Directory domain which is configured during installation and configuration.

How to Register a Security Provider

To register a new security provider, two tables in the HostServer database must be modified:

• 
  
• SecurityProviders – In order to register the security provider as a Type that implements IHostableSecurityProvider
  
• SecurityLabels – This table maps the security provider to a label and stores initialization data
  

Security Label

K2 blackpearl allows for multiple security providers to be used for authentication purposes. This allows a customer’s security provider to be modified when business requirements change, or to allow for multiple security providers for use with K2 Host Server.

Typically, the authentication mechanism is Active Directory (AD) or SQL. Both AD and SQL providers ship in the box with K2 blackpearl. However, custom security providers can be written for other sources (such as Oracle, LDAP).
