No password prompt after wrong entry

No password prompt after wrong entry

[Ariel D'Alessandro]

Hi all,

I have a question regarding the expected behavior on connmanctl.

After trying to connect to a network using a wrong password, connman
returns `connect-failed`. Further attempts to connect won't prompt for a
new password, so it will use the same old wrong one and keep returning
`connect-failed`.

After manually removing the network, re-connecting will prompt for a new
password and the connection will succeed. Is this the expected behavior
or it should automatically prompt after a wrong password entry?

See logs:

```
connmanctl> connect wifi_42ed868596d0_415045525449535f4150_managed_psk
Agent RequestInput wifi_42ed868596d0_415045525449535f4150_managed_psk

What version of connman are you using?

There is a bug in 1.40 which was fixed by commit fe5c1436 ("agent:
Always inform upper layer via callback") that has precisely the symptoms
you're describing.

That's what I also thought. However, I'm using v1.41 which includes that
fix:

```
$ /usr/sbin/connmand -v
1.41
```
