About half the time I try to ack something in icinga I get a permission denied error. That is because for some reason I have two icinga accounts, one is "Andrew Bogott" and one is "andrew bogott".
"Andrew Bogott" is the account name I use on every other wmf website but that account does not have the access rights to do anything in icinga. "andrew bogott" has the rights I need on icinga but I never remember to log in that way.
Also, icinga sessions are long-lived and icinga doesn't present a 'log out' button so once I've logged in as Andrew Bogott I have to live with it for weeks or do some kind of fancy thing to clear my cookies.
I know I am not the only person suffering from this issue and it is extremely annoying and disruptive, causing many mistaken pages and delayed acks.
