I regularly used to use Remedy in my previous duties. And okay, the authentication process does output a message specifying whether the user exists or not, and that is not a desirable aspect of any system. I would like to say however, that Remedy was the most efficient system that I was aware of during the time of providing support with multiple systems+users. It has its problems, though I think it is fairly stable. And largley stable compared with other 'supposed call logging systems'. Having said that, I have not had any time to poke n probe it at all. Seeing as most call logging systems for IT support are provided within a LAN/Secure W/LAN environment, the issue seems to be not so URGENT/SERIOUS. I mean, it is far easier to track instances of authentication login attempts in such a scenario, given certain security enforcements and params. I would think, others may disagree. Yes, systems should not report whether a user does or does NOT exist, and such systems as Remedy can be used within any environment. But you would have to think that sys-admin's with any sense about them, would be aware to such issues with 3rd party app's, and take action accordingly ... | dot dot dot |
