I am using:
$auth["session"] = "host";
$auth["type"] = "db";
Host authentication takes in session uid from SAML - this works fine on every other part of version 1.4.10. Then authenticates based on uid=username on the database. I have this working perfectly with 1.4.09.
In version 1.4.10 edit_users.php I can add the first user and update that user except for its rights. When I try to add another user it goes through the entire process, with no php errors but never adds the user to db - again no errors. When I take the edit_users.php version 1.4.09 it allows me to add or edit new users based on perms... albeit with a lot of warnings because it looks like there were a lot of changes to the file in new version.
