SEC-3106: Option in BasicAuthenticationFilter to log more exception info

[spring-projects-issues]

Bill Chen (Migrated from SEC-3106) said:

The current code in doFilterInternal() logs in this way:

logger.debug("Authentication request for failed: " + failed);

which, in most cases just produces: "Authentication request for failed: org.springframework.security.authentication.BadCredentialsException: Bad credentials". This is neither a correct sentence nor useful for debugging.

Could it be changed so it logs the stack at trace level or something?
