Description of problem:

Since sssd 1.13 has been crashing, downgrading to 1.12, seems to solve the
problem.

I get the following trace:

Version-Release number of selected component (if applicable):

sssd-1.13.0-7.fc23.x86_64

How reproducible:

Config sssd with something like this:

[sssd]
config_file_version = 2
reconnection_retries = 3
sbus_timeout = 30
services = nss, pam, autofs
domains = default

[nss]
filter_groups = root
filter_users = root
reconnection_retries = 3

[pam]
reconnection_retries = 3
[domain/default]
auth_provider = ldap
ldap_tls_reqcert = never
ldap_id_use_start_tls = True
cache_credentials = True
ldap_search_base = dc=foo,dc=bar
krb5_realm = EXAMPLE.COM
chpass_provider = ldap
id_provider = ldap
use_fully_qualified_names = False
store_legacy_passwords = False
debug_level = 0
min_id = 100
ldap_uri = ldap://example.com
enumerate = True
autofs_provider = ldap

ldap_tls_cacertdir = /etc/openldap/cacerts
[autofs]

and enable sssd in authconfig.

Start sssd service and wait for crash.

Caused by commit bdc2ace
and locale setting.

The workaround is to use simple locales without unicode characters.

e.g. to add line "LANG=C" to the /etc/sysconfig/sssd.
