Unable to chain multiple LDAP authentications, either using FastBindLdapAuthenticationHandler or BindLdapAuthenticationHandler. The first LDAP authentication that fails makes the whole authentication fail (an AuthenticationException is thrown indeed).

In order to work, I made a workaround in the org.jasig.cas.authentication.AuthenticationManagerImpl.authenticateAndObtainPrincipal by replacing

} catch (final Exception e) {
handleError(handlerName, credentials, e);
}

with

} catch(final AuthenticationException ae) {
log.info("{} failed authenticating {}", handlerName, credentials);
} catch (final Exception e) {
handleError(handlerName, credentials, e);
}

Do you think you could integrate this workaround in the cas-server-core release ?

Best Regards
