Subject: [PATCH] Replace the example sssd.conf file with the one used in Fedora
Also remove the [services/infopipe] section, since we're not
shipping InfoPipe yet, and that would be confusing.

Subject: [PATCH] Make reconnection to the Data Provider a global setting
Previously, every DP client was allowed to set its own "retries"
option. This option was ambiguous, and useless. All DP clients
will now use a global option set in the services config called
"reconnection_retries"

From 9fc454c84d539cd90aed3a74a350bdc792455407 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fixing memory issues in ini and collection
The read_line() function used an internal buffer allocated on stack
as temporary storage for a line read from file, then returned it.
read_line() now gets a buffer from the caller.
Fixed memory leaks in INI and Collection found by valgrind.
