Zeid: do you mean 'sign into Moodle' in which case the answer is yes, such an authentication plugin could be written.
If you mean 'log into their machines' (like for instance in a Novel Network) the answer is probably no. Linux may be a different kettle of fish. It is Open Source.

i was thinking of it that it may be used to enhance the login process....now obviously security would be thrown out the window but it would be nice to mix it up. the code of ethics also know as a code of conduct is a manual by which employees ought to conduct themselves in a company. this is annually revised and changed so employees always need to be updated about.
Zeid, it may be more than just code of ethics, as then ANYONE can go through company's code and log in, unless its on secure intranet only. It may be implemented so employees are well aware of their company's code.
