+dnl EVO_LDAP_CHECK(default)
+dnl Add --with-openldap and --with-static-ldap options. --with-openldap
+dnl defaults to the given value if not specified. If LDAP support is
+dnl configured, HAVE_LDAP will be defined and the automake conditional
+dnl ENABLE_LDAP will be set. LDAP_CFLAGS and LDAP_LIBS will be set
+dnl appropriately.
