Description of problem:


Version-Release number of selected component (if applicable):
sssd-1.5.1-5.el6.x86_64

How reproducible:
Always, with the specified sssd.conf I could reproduce this after every 3 successfully renewed TGT for user.

Steps to Reproduce:
1. Configure sssd for krb5 authentication.

relevant domain section of sssd.conf:
[domain/default]
krb5_lifetime = 120
ldap_tls_reqcert = demand
ldap_id_use_start_tls = False
krb5_realm = EXAMPLE.COM
ldap_search_base = dc=example,dc=com
debug_level = 9
id_provider = ldap
auth_provider = krb5
ldap_tls_cacert = /etc/openldap/cacerts/cacert.asc
chpass_provider = krb5
ldap_uri = ldaps://sssdldap.idm.lab.bos.redhat.com:636
krb5_renew_interval = 10
enumerate = False
krb5_kdcip = sssdldap.idm.lab.bos.redhat.com:88
cache_credentials = False
krb5_kpasswd = kerberos.example.com
krb5_renewable_lifetime = 150m
krb5_ccname_template = FILE:%d/krb5cc_%u
ldap_tls_cacertdir = /etc/openldap/cacerts
krb5_ccachedir = /tmp/krb5_cache

2. Login as a user.
3. Wait until the successful TGT renewals for more than 3 times.
  
Actual results:
sssd crashes

Expected results:
sssd should not crash.
