Using the windows authentication

Question

In my application , I would like use Windows authentication .Currently I am using basic authentication in which the application will get the user details from a file.The file will contains users password and access right(read write permissions). I would like to enhance it with windows authentication in which my application take the windows user and allows him to use the application. Is it possible? If possible , can I set some attributes(like for xxxx value is 1, yyyy value is 2 ) for windows users. Kindly help me if it is possible in Java.

Apart from transfer logins scripts Ashwin and Stan mentioned, I usually run following script in order to re-establish orphan users to establish if any SQL logins.
set nocount on
declare @username    sysname,
        @errcode     int
select @errcode = 0
select @username = min(name)
from sysusers (nolock)
where uid <> gid and
      name not in ('guest', 'sys', 'INFORMATION_SCHEMA') and
      suser_sname(sid) is null and
      issqlrole = 0
while @username is not null
begin
   if exists (select 1
              from master.dbo.syslogins (nolock)
              where name = @username)
   begin
      exec sp_change_users_login @Action = 'Update_One',
                                 @UserNamePattern = @username,
                                 @LoginName = @username
      select @errcode = @@error
      if @errcode = 0
         print 'The user ''' + @username + ''' was re-established in database!'
      else
         print 'Failed to re-establish user ''' + @username + ''' in database!'
   end
   else
   begin
      print 'The user ''' + @username + ''' does not have login ID. So, drop it from database!'
      exec sp_dropuser @username
   end
   select @username = min(name)
   from sysusers (nolock)
   where uid <> gid and
         name not in ('guest', 'sys', 'INFORMATION_SCHEMA') and
         suser_sname(sid) is null and
         issqlrole = 0 and
         name > @username
end
go
