Unbreak reading username-password from management

Fix a bug introduced by commit 6e9373c84639382c16d9eb8f1f78f60079bb89df

---
Without this, management-query-passwords is broken. After successfully taking the username and password from management the code falls to the if block where it is prompted from stdin.
As authfile defaults stdin, the read-from-stdin block should be in an else clause as in the previous version. Oh boy, those if-else blocks are too long and far too many..
