Changeset 319 for trunk/dns.cgi

Timestamp:

Refine permissions handling:

• self_edit now has meaning; the user can edit (or delete) their own account but not others.
• Check on each request to see if a user was disabled, otherwise a user could keep their session active just by making a request just before the session expiry, indefinitely.
• Don't allow non-superusers to make changes to a superuser account

File:

• trunk/dns.cgi (modified) (5 diffs)
