public class RunAsImplAuthenticationProvider
An AuthenticationProvider
implementation that can authenticate a RunAsUserToken
.
Configured in
the bean context with a key that should match the key used by adapters to generate the RunAsUserToken
.
It treats as valid any RunAsUserToken
instance presenting a hash code that matches the
RunAsImplAuthenticationProvider
-configured key.
If the key does not match, a BadCredentialsException
is thrown.
