Samba clear text password exposure

The following text was taken from the samba advisory:

The machine trust account password is the secret shared
between a domain controller and a specific member server.
Access to the member server machine credentials may allow
an attacker to access additional information regarding
user accounts in the domain.

The winbindd daemon included in Samba 3.0.21 and subsequent
patch releases (3.0.21a-c) writes the clear text of server's
machine credentials to its log file at level 5.  The winbindd
log files are world readable by default and often log files
are requested on open mailing lists as tools used to debug
server misconfigurations.


Please note our samba log files are stored in a directory which is
only readable by root.
