Problem with mosquitto_passwd when updating existing user

[Lestat-GitHub]

Hi, I'm having trouble with mosquitto_passwd command when trying to update an existing account.

Mosquitto version: 1.6.9
OS: Ubuntu 20.04

My config file looks this :

password_file /etc/mosquitto/mosquitto.users
allow_anonymous false

If I try to create a new file from scratch using mosquitto_passwd -c mosquitto.users test
everything is ok and I can connect using mosquitto_sub -h 10.1.1.124 -u test -P password --topic "/test"

But if I try to update the password of existing 'test' account with :
mosquitto_passwd -b mosquitto.users test password

I'm not able to connect anymore and get:

mosquitto_sub -h 10.1.1.124 -u test -P password --topic "/test"
Connection error: Connection Refused: not authorised.

NOTE: If I create a file containing test:password and try to convert it using mosquitto_passwd -U mosquitto.users, everything is ok too...

Seems like updating an existing password this way if not functional.

Please find a 'working' and 'not working' password file content:

Good

Thanks for your help.

You are correct, thanks for reporting it. Updating passwords using -b doesn't work in 1.6.9. This was reported already in #1664 and fixed, and will be in 1.6.10.

Thanks for your answer, and sorry I didn't see that an issue was already opened...

I can then close this one ;)

No problem, I wouldn't expect people to look at already closed issues.
