NullPointerException using MS SQL Server driver with JDBCRealm

           Summary: NullPointerException using MS SQL Server driver with
                    JDBCRealm
           Product: Tomcat 4
           Version: 4.0.6 Final
          Platform: PC
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: rduncan@bds.com


In attempting to configure the JDBCRealm for use with MS supplied SQL Server 
driver, the JDBCRealm gets a NullPointerException. From the server.xml:

      <Realm className="org.apache.catalina.realm.JDBCRealm"
             connectionName="user"
             connectionPassword="password"
             
connectionURL="jdbc:microsoft:sqlserver://parkcity:1433;SelectMethod=cursor"
             debug="99"
             driverName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
             userTable="Users"
             userRoleTable="UserRoles"
             userRoleNameCol="rolename"
             userNameCol="username"
             userCredCol="password"
             />

>From the Log File:

2003-04-22 14:55:57 JDBCRealm[Standalone]: Username rduncan successfully 
authenticated
2003-04-22 14:55:57 HttpProcessor[8080][3] process.invoke
java.lang.NullPointerException

   .
   .
   .

The user's credentials (pwd) are successfully authenticated. The 
NullPointerException happens as the method attempts to collect the user's roles.
