Try Kerberos with two 'r's
However Kerberos is a protocol, not an app.
If you want a more complete and flexible solution for corporate authentication, authorisation and accounting (AAA) encompassing external network access across the Internet, alternatively check out the RADIUS protocol.
Any half-decent enterprise Linux distro should have suitable services for both these available.
Another thing you might want to think about is your email server: there are some pretty good Outlook substitutes around, though if your managers rely on horrible things like public folders or specialised apps that dig deep into the Outlook/desktop API, you will need to choose with care. I know at least one large outfit that has recently disabled public folders for this among other reasons.
Oh yeah, and for those specialised legacy apps that are tailored to IE, there is a neat Firefox extension for Windows called IETab. It basically fires up IE in the tab, so you can browse IE-specific services. IE can have trouble with the standards-compliant web interfaces Linux services, so Firefox plus IETab gives access to the whole lot, as well as giving more secure and flexible browsing of the public Internet.
So yes, Linux server / Windows client corporate environments are being increasingly do-able and increasingly seen. However be warned, it can be hard to root out (sic) all your Windows servers and you might spend quite a while with a mixed ecology.
