restart strategy for extauth

headers Jesse Thompson | 7 Sep 2011 22:01

It won't be restarted, so you will need to use your server monitoring 
tools to make sure that the program is running.

If your extauth program is complex (and consequently crashy), or you 
just want the ability to change or restart the program after it is 
already started, then I suggest you take a look at my post from 
7/13/2011 with Subject "Re: [ejabberd] multiple authentication methods: 
order and priority of operation" where I discuss an approach that allows 
you to restart your extauth program without restarting ejabberd.
