Right now, it is impossible to configure the ldap* command line tools so that
they function in major circumstances w/o also having a configuration file (I.e.,
ldap.conf, .ldaprc, etc).  For example, the ability to use startTLS with LDAP
requires such a file so that the CA file and/or cert path for the tool can be
defined.

The "-o" option should be expanded to cover additional configuration parameters
from the conf file, as has already been done with the network timeout parameter.
