Description Piviul 2017-07-14 13:46:13 UTC 
Hi, after upgrading ubuntu to 16.04 LTS (samba 4.3.11) I found that winbind  doesn't resolve user/group informations. I have to restart winbind a few times to have it begun to works again. Seems a regression of the bug 8371 (https://bugzilla.samba.org/show_bug.cgi?id=8371). I found a workaround. I have created the script /usr/local/sbin/winbind_restart.sh:

# cat /usr/local/sbin/winbind_restart.sh
#!/bin/bash

wbinfo -u 2>&1 > /dev/null;
if [ $? -eq 1 ]; then
    service winbind restart 2>&1 > /dev/null; 
    #  ci riprovo fra 1 minuto
    TIME=$(date -d '+1 min' +%H:%M);
    echo $0 | /usr/bin/at $TIME > /dev/null 2>&1;
fi

and I put /usr/local/sbin/winbind_restart.sh in /etc/rc.local. In a few minutes with this workaround the user can logon again.

I know, is a very rough workaround but I found no other way... :(
