RE: How to authentificate an user via telephon?

One suggestion is:

Verify his name matches his physical desk location identification in your
records and call back the phone number you have on record to give them the
new temp password.

Hello colleauges,

imaging the following situation:

User calls the helpdesk to reset/alter some kind
of account-password (NT, RAS, PKI-PIN ...) and you
has to determin wheter the user is the correct
(owner of the account) user. What would you do
to authentificate the users identity?

What are good methodes to do this? It should be
easy for the user but secure for the administration.
