# Module: LDAP Authenticate
22
# Pluggable authentication module for LDAP servers.
23
# This will read the ldap_url and ldap_format_string config variables.
24
# This module is NOT active implicitly - it must be specified in the
25
# "auth_modules" config string.
26
# However, setup.py should configure it in auth_modules by default.
