I could login via LDAP but I cant fetch user role which is stored in my Database. I do get the following error:


org.springframework.security.ldap.userdetails.LdapUserDetailsImpl cannot be cast to com.test.rnd.geo.web.dto.CustomUser

What I have tried:

private CustomUser getUserDetails() {
CustomUser userDetails = (CustomUser) SecurityContextHolder.getContext().getAuthentication().getPrincipal();

LOGGER.info("Deatils: "+userDetails);
LOGGER.info("UserName: " + userDetails.getUsername());
LOGGER.info("Auth Token: " + userDetails.getAuthToken());
LOGGER.info("User Role size: " + userDetails.getAuthorities().size());
LOGGER.info("User Role : " + userDetails.getAuthorities());


return userDetails;
}
I am getting error to fetch this getUserDetails() function.

CustomUser customUser = getUserDetails();
String role = customUser.getAuthorities().stream().findFirst().get().getAuthority();
