[Users] LCR module

Hi all, The new lcr module has now two modes of operation controlled by the direct_db parameter: - direct_db = 1 (no DB caching) This is the old behavior of the lcr module - direct_db = 0 (DB caching - default one) In this mode, the 1.7 TODO issue from the README file is addressed: no more SQL query in load_gws() function. In addition to this, the From URI from the lcr table is now a POSIX regular expression, with the following extension: if the From URI is an empty string, it will be considered as a universal match - ie .* without invoking the regexec function. Migrating from the old mode to the new mode requires the from_uri column from the lcr table to be updated to use POSIX regular expressions instead of the special _ and % characters. Example: old from_uri -> new from_uri ------------------------------ % -> 123% -> 123.* regards Ovidiu Sas
