             Summary: Missing search-base-dn in identity-mapping of Elytron ldap-realm causes NPE
                 Key: ELY-858
                 URL: https://issues.jboss.org/browse/ELY-858
             Project: WildFly Elytron
          Issue Type: Bug
            Reporter: Ondrej Lukas
            Assignee: Darran Lofthouse


In case when attribute {{identity-mapping.search-base-dn}} from Elytron ldap-realm is missing in configuration then calling ldap-realm during authentication causes NullPointerException.

Following exception is thrown to server log:
