AppArmor doesn't modify, enforce, or even notice, the standard unix permissions. AppArmor -can- cause applications to fail due to insufficient permissions, but that happens completely orthogonal to the standard unix discretionary access controls. When AppArmor rejects permissions, it will log the failure to /var/log/audit/audit.log (if the audit daemon is running) or /var/log/messages (if auditd isn't running, and syslog has a standard-enough-configuration). Run "aa-logprof" at an unconfined root prompt to be walked through modifying AppArmor profiles. If it quickly returns, then AppArmor isn't at fault. :) (The yast gui also has some online help, which may help to answer some questions; you may prefer it.) For the permissions changing, I can only think of /etc/permissions* -- but I don't know this system well.
