sssd version: sssd-1.10.0-5.fc20.beta1

The domain section in sssd.conf has:

[domain/ADTEST]
debug_level = 0xFFF0
id_provider = ldap
ldap_uri = ldap://example.adtest.com
ldap_schema = ad
ldap_default_bind_dn = cn=Administrator,cn=Users,dc=adtest,dc=com
ldap_default_authtok = XXXXXX
ldap_tls_cacert = /etc/openldap/certs/ad_cert.pem
ldap_referrals = false

"getent passwd " causes sssd_be to crash

The initial part of the backtrace shows:

Core was generated by `/usr/libexec/sssd/sssd_be --domain ADTEST --debug-to-files'.
Program terminated with signal 11, Segmentation fault.
