Subject [jira] [Created] (KARAF-2913) JAAS JDBCBackingEngine has the wrong condition to iterate results, no users are returned
Date Tue, 15 Apr 2014 13:44:15 GMT
Mike Hummel created KARAF-2913:

             Summary: JAAS JDBCBackingEngine has the wrong condition to iterate results, no
users are returned
                 Key: KARAF-2913
                 URL: https://issues.apache.org/jira/browse/KARAF-2913
             Project: Karaf
          Issue Type: Bug
          Components: karaf-security
    Affects Versions: 3.0.0
            Reporter: Mike Hummel

In the library org.apache.karaf.jaas.modules in
JDBCBackingEngine in line 195 is the following code:

                while (!usersResultSet.next()) {

this should be

                while (usersResultSet.next()) {

to iterate the results of the query.

An empty USERS table causes the following error - as estimated:

java.sql.SQLException: Illegal operation on empty result set.

You have the same issue in line 245:
                while (!rolesResultSet.next()) {
