Does Drupal cache permissions? If so, how can I clear that cache for a particular user at a particular time? I have a module, og_user_roles (http://www.drupal.org/project/og_user_roles), which adds group roles to the $user object when it is loaded. So, when function "user_access" executes, my module looks to see if the user is in a group context, and if so, adds whatever role(s) the user might have within that particular context. A user is having a problem that he explains here: http://drupal.org/node/164932. In short, each time he clicks on a new group link, and the group menu is calculated (i.e., what nodes the user can create), the user still initially has the same roles from the previous group instead of the new group. Therefore, the group menu will display "create" links for which the user may not necessarily have permissions in this group. My guess is that there is some role/permissions caching going on so that, for some reason, the $user object isn't loaded when the user initally enters the new group, so the permissions remain the same as before when the new group menu is calculated. If I'm correct, then I need to figure out a way to clear this cache so that the correct group menu links will always be calculated and displayed. Thanks in advance for any suggestions. -ron -- Ron Parker Software Creations http://www.scbbs.com Self-Administration Web Site http://saw.scbbs.com SDSS Subscription Mgmt Service http://sdss.scbbs.com Central Ave Dance Ensemble http://www.centralavedance.com R & B Salsa http://www.randbsalsa.com
