# == Description
#
# Create a new URI::LDAP object from components, with syntax checking.
#
# The components accepted are host, port, dn, attributes,
# scope, filter, and extensions.
#
# The components should be provided either as an Array, or as a Hash
# with keys formed by preceding the component names with a colon.
#
# If an Array is used, the components must be passed in the order
# [host, port, dn, attributes, scope, filter, extensions].
#
# Example:
#
# newuri = URI::LDAP.build({:host => 'ldap.example.com',
# :dn> => '/dc=example'})
#
# newuri = URI::LDAP.build(["ldap.example.com", nil,
# "/dc=example;dc=com", "query", nil, nil, nil])

# == Description
#
# Create a new URI::LDAP object from generic URI components as per
# RFC 2396. No LDAP-specific syntax checking is performed.
#
# Arguments are +scheme+, +userinfo+, +host+, +port+, +registry+, +path+,
# +opaque+, +query+ and +fragment+, in that order.
#
# Example:
#
# uri = URI::LDAP.new("ldap", nil, "ldap.example.com", nil,
# "/dc=example;dc=com", "query", nil, nil, nil, nil)
#
#
# See also URI::Generic.new
