[galaxy-dev] DB access and passowrd field

Hi All, I have some tools that generate some tabular output. The next step is to aggregate the data for some filtering and analysis. In my view the best way to do by using a DB (MySQL in my case). Tools and cmd line wrappers can easily connect to this DB (another database than galaxy is using of course) when providing the details for access like address:port, username and password. Is there any way to embed a text field for a galaxy tool that is of type password or blinded? Don't want to share user specific login details when sharing histories or galaxy pages.Or is this a bad thing to pursue anyway? Thanks for any directions. Alex
