Could you provide a core dump and/or full backtrace?

Comment 4 Derek Warren 2012-12-13 16:22:51 UTC 
This Cyrus bug report may be relevant:
https://bugzilla.cyrusimap.org/show_bug.cgi?id=3445

I'm seeing the same behaviour here when SSSD tries to do an ldap_sasl_bind() to our Win2K8 R2 AD DC.

Downgrading as outlined above fixed the issue for me as well.

Attaching ABRT output including a coredump and backtrace.
Comment 5 Petr Lautrbach 2012-12-20 15:40:00 UTC 
Yes, this is relevant to the Cyrus bug. At the same time, I overlooked two constants change in header files. Due to this change, openldap and maybe two other projects need to be rebuilt. So I've unpushed cyrus-sasl-2.1.25-2 from F18.

I'll push 2.1.26 to Rawhide soon and I'll send an announce to the other project maintainers that rebuild is needed.

Thanks for investigation.
Comment 6 Petr Lautrbach 2013-05-29 15:57:23 UTC 
cyrus-sasl-2.1.25-2.fc18 was unpushed from Fedora releases.
