I cannot definitely say from backtrace why sssd crashed,
but it crashed on line:
           strcasecmp(state->dns_domain, state->backup_domain)
It looks like backup_domain is valid, but dns_domain is NULL.

Could you also attach coredump?
Is there any interesting error message in domain log file?

So far we haven't been able to save the coredump or retrieve any logs. Will attach the coredump when we see the same crash again.

Comment 5 Lukas Slebodnik 2013-12-04 14:10:19 UTC
As I thought dns_domain is NULL

(gdb) p *state
$2 = {
  ev = 0x7f82be8c4640, 
  resolv_ctx = 0x7f82be8cf2b0, 
  service = 0x7f82be9014d0 "ldap", 
  protocol = 0x7f82be901540 "tcp", 
  primary_domain = 0x7f82be90b350 "Default-First-Site-Name._sites.sssdad2012.com", 
  backup_domain = 0x7f82be900880 "sssdad2012.com", 
  dns_domain = 0x0, 
  primary_servers = 0x0, 
  num_primary_servers = 0, 
  backup_servers = 0x0, 
  num_backup_servers = 0
