It cannot find your backupkey, now whether this is down to your rather
strange smb.conf is debatable, but I would suggest that you remove these
unneeded or default lines:
server string = AD DC
ldap admin dn = cn=Administrator,cn=Users,dc=tkt,dc=com
hostname lookups = no
guest account = nobody
wins support = yes
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536
SO_SNDBUF=65536
getwd cache=yes
min receivefile size = 16384
os level = 80
There was a bug similar to this:
