Hi Chris,

Simo kindly provided a patch that sets the cyrus-sasl option that might
be helpful in your environment. Would you mind testing it out? 

I can build you a test RPM of both SSSD and cyrus-sasl[1] with the patch
for you to try out.

If you can build the test packages on Ubuntu yourself, that would be
much easier as 12.04 already contains cyrus-sasl-2.1.25 which supports
the option we need.

[1] hopefully. I haven't tried backporting the patch but it looks easy
enough.
