# local authentication using ldap
# To use this package, you will also need the following:
# perl-ldap-0.31.tar.gz
# which in term requires
#  Authen-SASL-2.04.tar.gz
#  Convert-ASN1-0.17.tar.gz
#  IO-Socket-SSL-0.92.tar.gz
#  Net_SSLeay.pm-1.23.tar.gz
#  XML-SAX-Base-1.02.tar.gz
#
# One of the packages may prompt you to update the openssl, so you may also
# need openssl-0.9.7b.tar.gz
#
# Above were the versions used at fsu. 
#
# To implement it on your local system, complete the variable assignment below.
#
# See notes beside each variable.
