HI satish,
well you can do this by binding the readonly or enable property of the input field to a context attribute of boolean type and then checking in the wddoinit method for the user authentication. If the user is authenticated then you can set the attribute to true.
Authentication can be done by providing all the users with a role (say enable) for which you want the fields to be enabled and you can check for the roles of the logged in user and if that particular role is pesent there you can enable the fields.
The following is the code that you can write in your Wddoinit method for the work.
String strUserName = null;
     boolean rolestrflg = true;
   try {
           IWDClientUser clusr = WDClientUser.getCurrentUser();
            IUser sapUser = clusr.getSAPUser();
     if (sapUser != null) {
                         IUserAccount[] acct = sapUser.getUserAccounts();
          if (acct[0] != null) {
                                   strUserName = acct[0].getDisplayName();
                               Iterator rolesit = sapUser.getRoles(true);
               IRoleFactory rfact = UMFactory.getRoleFactory();
               while (rolesit.hasNext()&& rolestrflg) {
                                             String roleName = (String) rolesit.next();
                                             IRole role = rfact.getRole(roleName);
                          if(role.getUniqueName().equalsIgnoreCase("Enable")) // suppose the role for enabling the fields is Enable
                               wdContext.currentContextElement().setContrl(true);
                               rolestrflg = false;
                          else
               wdContext.currentContextElement().setContrl(false);
     } catch (Exception e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
i hope this will solve your problem
