Since i can remember, the Default Keyring bug has existed in Ubuntu popping up every time the network manager wants to connect to my wireless network. The only way to get around this bug is to remove the password for the default keyring which therefore exposes all you passwords to any one who knows where to look. This is a major security issue that i've overlooked for far too long.
Now for the first time since i started using Ubuntu i need change my password. I went to "Users and Groups" and changed the password and got a comforting "Your password has been changed" message. I would normally carry on with my tasks and forget about it but because of the Default Keyring bug i thought i'd better make sure things are as they should be. I logged out and attempted to log back in with my new password.
No luck, the new password is sternly denied and the old password is accepted. Unbelievable, Linux security is something i've often boasted about but the truth is the security in Ubuntu is in a shocking state and has been this way for years. This is not acceptable.
