Replace a credential only if unchanged when re-hashing a password - #55052
Merged

Conversation
Add updateStoredCredential(oldCred, newCred) that replaces a stored credential only if it still has the content of the old version, using a pessimistic lock in the JPA stores. Use it in the deferred password re-hash, so that it no longer overwrites a credential that changed after it was validated.
