#1776 possible segfault when backend callback is removed
Closed: Fixed Opened by pbrezina.

Closed: Fixed
Reopen Issue

Our API supports removing backend callback, but it doesn't work correctly. It still remains in DLIST which causes segfault during next execution of the callbacks. This currently affects sudo first full refresh, when online callbacks are executed several times before successful connection.

How to reproduce:

1. configure sssd with sudo support in such way it cannot connect to the server
   - tested with incorrect bindpw in ldap_default_authtok, but unreachable hostname should do the trick
2. run sssd
3. tell sssd to go online
   - kill -s SIGUSR2 $(pidof sssd_be)
   - sssd_be crashes when it tries to go online for second time
