Authentication

Hi,
I spent these days to add the login, register and so on features into my system.
Some things from Microsoft are really puzzles. For example, I want user in my system can input passwords without non-numeric symbols. And membership provider has the special attribute for it: minRequiredNonalphanumericCharacters. MSDN says: minRequiredNonAlphanumericCharacters, but it can't be recognized! Why??? The answer is very simple: because you should write minRequiredNonalphanumericCharacters, not minRequiredNonAlphanumericCharacters. Feel the difference?
There a lot of work: register, login, login failure, activate, activation failure and so on.
Bye
Time spent: 4 hours
