Helo, everybody. I have an issue concerning access modules. Table node_access has too many lines. (nid * role_id) Concerning taxonomy_access, there is an idea to remove (and not generate) those lines in table 'node_access' where all three types of grants are 0.(grant_view = 0 and grant_upadet = 0 and grant_delete = 0). Because actually only records which grants some permission affect node_access() behaviour. What do you guys, think about it? Does this have any drawback in your opinion? For troubleshooting or to be able to check integrity of table 'node_access', I would definitely generate at least one line per node, even if it is filled with zeros. (so that all 'nid' would be inside table 'node_access'). I have an issue with Taxonomy_access about this: 'Prevent taxonomy_access from populating node_access table more than necessary.' http://drupal.org/node/54544 Many thanks for the support in advance. Have an ice weekend :) Keve.
