This should be easy, but I can't figure out what I'm doing wrong: In my Drupal 7 site, I've defined a content type in the usual way. I want regular users to be able to create instances of that type, but not edit them. Trivial, right?
The content type is in place, and, in admin/people/permissions, there are entries like "My Type: Create new content" and "My Type: Edit own content". I've set the checkboxes so authenticated users have "create new content" permission but not "edit own content" permission. Just to be on the safe/superstitious side, I've cleared the cache and done a Rebuild Permissions. But, nevertheless, my regular users can still edit their nodes.
Shouldn't this work / any ideas what's wrong? Do I need to write a _node_access handler?
