org.apache.shiro.authc.pam
Class AtLeastOneSuccessfulStrategy

java.lang.Object
  extended by org.apache.shiro.authc.pam.AbstractAuthenticationStrategy
      extended by org.apache.shiro.authc.pam.AtLeastOneSuccessfulStrategy
All Implemented Interfaces:
AuthenticationStrategy

public class AtLeastOneSuccessfulStrategy
extends AbstractAuthenticationStrategy

AuthenticationStrategy implementation that requires at least one configured realm to successfully process the submitted AuthenticationToken during the log-in attempt.

This means any number of configured realms do not have to support the submitted log-in token, or they may be unable to acquire AuthenticationInfo for the token, but as long as at least one can do both, this Strategy implementation will allow the log-in process to be successful.

Note that this implementation will aggregate the account data from all successfully consulted realms during the authentication attempt. If you want only the account data from the first successfully consulted realm and want to ignore all subsequent realms, use the FirstSuccessfulAuthenticationStrategy instead.

Since:
0.2
