    XMLWordPrintable

Details

    Description

      When referral mode 'throw' is configured for LDAP outbound connection which is used by legacy LDAP security realm and its groups are assigned through principal-to-group LDAP authorization then it finishes with NPE. It causes that Management Console returns status 500 when referral mode 'throw' is used for group searching user includes referral role.

      It can be reproduced by using configuration from [1] with referral mode 'throw'.
