First of all let me clarify some things:
* The change in the libini was discussed here on the list and agreed to.
* Also the fact that leading spaces are treated as wrapper is the
default behavior of the library was agreed to.
* The change to the ini library was requested and was actually
proposed to rely on leading spaced rather than "\"
* My opinion as an implementer was that "\" a better choice but I was
talked out out of it.
* There is a ticket to allow wrapping by "\" but it is deferred as
there is no one asking for it
* The fact that SSSD took the defaults when switched to the new
version is a bug and needs fixing
* Moving forward SSSD should stay backward compatible but allow people
to use wrapping if they want. This will be enabled via SSSD startup
command line arguments as noted in the ticket. Ticket to do that is
deferred till future.
