             Summary: Elytron Ldap Realm searches roles before validating password when direct verification and referral mode follow are used
                 Key: ELY-970
                 URL: https://issues.jboss.org/browse/ELY-970
             Project: WildFly Elytron
          Issue Type: Bug
            Reporter: Ondrej Lukas
            Assignee: Darran Lofthouse
            Priority: Critical


In case when Ldap Realm is set to use direct verification and referenced DirContext uses referral mode follow, then roles for referral user are searched before actual user password is validated. In this case following flow is used:
# searching for username
# searching for roles (i.e. searching for attributes)
# validating password for username

It means even if wrong password is used then roles in LDAP are searched. Password should be validated before some roles are searched. Current behavior can result to performance issues.

This is the same issue as JBEAP-7339 but only for case when direct verification and referral mode follow are used and user from referral tries to authenticate.
