When starting an identify operation we allocate a gallery of prints from the
gallery, although if we match one of them we get that back in the finish
callback but with a further reference added.
So, in order to clean it up, use an auto-pointer or we'd end up in leaking
it, and the address sanitizer was catching this in our tests already:
Indirect leak of 12020 byte(s) in 5 object(s) allocated from:

Licensed under the GPL version 2 or any later version (see COPYING). A PAM login module is included in the 'pam' directory. API use cases ============= - User wants to use the fingerprint reader, and enroll his fingerprints, or remove some fingerprints from the database - Administrator wants to enroll fingerprints for a particular user, or remove fingerprints for a particular user - Laptop/desktop authentication: * Check for fingerprint devices * Check whether a particular user has any fingerprints enrolled * Verify a fingerprint for a particular user, or, if the device supports it, verify that the fingerprint matches against any of the fingerprints enrolled - Point Of Sale authentication (in a bar, the fingerprint reader is used to see who accesses a particular point of sale/till, in place of PIN code authentication and/or tokens) * Given a list of users, verify which one has scanned their finger
