Action: opened

PR body:
"""
Since dbus-1.11.18 DBUS_COOKIE_SHA1 respect $HOME variable
and fallback to value returned from getpwnam only if env HOME
does not exist. It caused problem for dbus communication
between sssd processes because local user usually do not have
directory $HOME/.dbus-keyrings/. And directory created in cwrap
environment is problmatic

[build@host ~]$ ls -ld ~/.dbus-keyrings/
drw-------. 2 build build 6 Oct  3 10:44 /home/build/.dbus-keyrings/

[buildhost ~]$ ls -lna ~/.dbus-keyrings/
ls: cannot access '/home/build/.dbus-keyrings/.': Permission denied
ls: cannot access '/home/build/.dbus-keyrings/..': Permission denied

[build@host ~]$ touch ~/.dbus-keyrings/test
touch: cannot touch '/home/build/.dbus-keyrings/test': Permission denied

Other alternative would be to set env variable HOME to the
same value as in fake passwd file:
  HOME=$(abs_builddir)/root
