#19 Take bind password from file.

[Devin Reade]

Right now, I believe that the only way to get cpu to use a
bind password is either on the command line or by
hardcoding
it into the cpu.conf file.

I would like to see it support reading the password
from a specific
file, much like the ldapsearch "-w" flag. The benefit
of this is
that:
1. One need not expose the password in the process
table,
as would happen with the cpu -w flag
2. One does not need to have multiple places in the
system
where the password is recorded. (That is,
there is no way
for them to get out of sync.)

BTW, this is a really nice utilitity. Thanks for
putting in the effort
on it.
