This extension works really well as a way to automate creation of users using an existing userbase.
I used it to link to the Trellis desk database and it worked like a dream once I had worked out that trellis used sha1(md5(password)) to encrypt passwords. The only disappointment for me is that it can't act as a bridge but I realise is that is very specific to each application.

What would be really nice if possible, would be to use curl to login to the other application using the supplied credentials.

The author has provided very flexible options for login/logout registration etc.. If you don't need bridging then this is a fabulous contribution..

Full marks from me..

Very easy to use, only two minor niggles 1. file overwrite on uploads is disabled by default which means you need to either hack the code to enable or remember to delete files before uploading 2. It would be nice if you could make the editor window bigger(and even better if it had line numbers and a find option! But apart from that it is a fantastic tool.. I use it every day!
