Hi,

is there chance how to authenticate user on website against user database in Drupal?
This can be very useful when we have projects on subdomains and users can login via account already created in main Drupal CMS (some kinf of external authentication for allowed websites). I try to find some existing modules but have no luck.

Thank you very much
