Updates for the External Authentication module happen infrequently. For instance, a new version is almost ready (and has been for months), but for the unit testing. The root cause of this is the fact that I got a 2 year old son (the module is older than that) and had a wife who was also working 4 days a week. It was very hard for me to find some time to update the module.
Three weeks ago, my wide died as a result of skin cancer (it went very quickly, the docters didn't even have time to formulate a treatment). So I'm a single dad now and fighting for some time to do my own things.
This means that I won't have any time left to look after this module for the coming years. I got the feeling that it is used now in quite a few places. So if anyone is willing to take over management of this module I would be very glad.
