I received an email supposedly from Apple ID people stating my Apple ID was locked due to security reasons and I needed to verify my identity or my account will be disabled. Is this ligitimate?

It's fake. Forward it to reportphishing@apple.com as an attachment and then delete it.

If an Apple ID actually gets locked, its owner will be told when they try logging into it instead of through email.

That email is an attempt by a scammer to obtain your Apple ID credentials.

Apple will never contact a customer, and ask for identity verification. Read: Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - Apple Support for phishing email identification/reporting tips.

It is phishing. Apple does not notify you about locking an Apple ID. You can check to see it is not locked by signing into iCloud.com.

Additionally a message Apple will always address you by your real name, never by your email address or Dear Customer. Also the sent-from address should be @apple.com or @itunes.com Additionally Apple does not send attachments.
