Hi.

As a basic security measure, you should always "hash" passwords before storing them inside your database. (Which would also solve your case-sensitive problem)

That is, rather than store the plain-text password the user gives you, run it through the sha1 function before storing it. (Or the hash function, if you need a stronger algorithm.)
That way the password will be safe even if somebody managed to break into your database.

To validate the password when the user wants to log in, you simply hash the password you want to check and compare the hashes.
