I'm having a problem with Portalkeeper. I'd like for most people on a range of IP addresses to be automatically logged in with a guest user account, and I've set it up so that its works. The problem is that they can't log out. They will sometimes need to log in with their own user account, for example to do something like posting a comment that requires a higher security role, but when they hit log out, they are automatically logged back in as guest users. They can't switch to any other account.
Can anyone give me a suggestion to deal with this issue?
