Re: [SSSD] [PATCH] Add callback when the ID provider switches from offline to online

[Stephen Gallagher]

Simo made some excellent suggestions on IRC, so I have incorporated them:

First, I changed the interface for be_add_online_cb() so that it will 
now take a mem_ctx and pass back (if requested) the online_cb object. 
(This object is now opaque). This way, the callback will be 
automatically freed if the parent context goes away for any reason.

I removed the be_remove_online_cb() function, so the interface to remove 
a callback will simply be to call talloc_free() on the opaque object 
returned from be_add_online_cb. This will allow us to potentially set 
the same callback function multiple times, with different private data.

New patch attached.
