An exception is thrown when trying to call resultSet.relative while retrieving next batch of users in Sql Server via the UserManager.

It looks like it may be SQL Server 2000-specific. There is a related exception in the logs:

java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Invalid call to ResultSet.Relative because there is no current row.
