Just a little near-death experience I had here... In a CMF site, thus in an acl_users not at the root, the CMF administrator had a Manager account. This administrator created all the site, skins, and so on. He also has an account at the root, with the same password. Now came the time for a cleanup, and deletion of the unneeded account in CMF. Then everything went weird, the site mostly worked but acquisition seemed to not find things, ZopeSecurityPolicy failed in validate (for instance if I put standard_html_header besides the object I accessed it worked, but if I left it in the skins it didn't)... It finally dawned on me that all the skins and so on were owned by the now nonexistent admin in the sub-acl_users, and that this caused all those problems. I re-added him. I probably could have "taken ownership" of all skins and CMF machinery from the admin at the root but I wanted to play it safe.
