[BUG] confusing init-adduser behavior when picking a USER_NAME which collides with system user

[chrishoage]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When specifying a USER_NAME and this user exists already (e.g. listed in /etc/passwd) usermod fails with an error and authorized_keys is looked up from /sbin

Currently this log is all that is present to signify there is an issue usermod: user 'sync' already exists

I missed this log initially and only saw it once I found the issue after looking at the ssh debug logs.

Expected Behavior

An error should be raised and the container should exit

Steps To Reproduce

Set USER_NAME to one of these users (I was using sync which was producing the error)

sync_server:~$ cat /etc/passwd
root:x:0:0:root:/root:/bin/sh
bin:x:1:1:bin:/bin:/sbin/nologin
daemon:x:2:2:daemon:/sbin:/sbin/nologin

[thespad]

So the TL;DR is that as www-data is an existing group we can't rename the abc group to that name, so it ends up changing the abc GID to 1001 and assigning that to the user instead.

It might be possible to change things so that in those cases where it's not an existing user but is an existing group we can handle it with a usermod -g. Can you open a new issue with your details and I'll try and find time to take a look at it.

in the second example, where it works because it doesn't recognize the key and continues to give access denied?

[thespad]

Not sure, should be looking at the same authorized_keys list in both cases.

Though FWIW in your use case you probably don't need to use www-data as the username, as long as the UID/GID are correct, which might get you around the problem.

solved after several tests, now it seems to work but with username/password, using the key it doesn't work

this way you have read and write permissions like www-data:www-data (33:33) and in the main server the files appear with the correct permissions
