Hi to all, I've searched a little in wiki to find a solution for VM user authentication through remote DB, but couldn't find enough hints. Anyone can give some idea about it?  Currently, I noticed that we can't store just user / pass for extensions in external DB and query when we need it, we should use mod_xml_curl and load the directory xml in this way. So, it would be included vm pass also, but problem comes when user changes his/her vm's pass. I couldn't find any method to handle it. Thanks for help. Regards,HY
