<p>re-compiled on an Ubuntu system, fresh from github.com:</p>

<pre><code>$ uname -a
Linux ubuntu-ae 4.10.0-19-generic

$ bitcoind -version

$ bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=123456 getbalance
0.00000000
</code></pre>

<p>and with wrong password:</p>

<pre><code>$ bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=1234564 getbalance
error: incorrect rpcuser or rpcpassword (authorization failed)
</code></pre>

<p>so s.th. is wrong with the sources? Or with Ubuntu setup. What kernel do you have (uname -a) ?</p>

<p>The error from the question could (and did in my case) arise because I did not use <code>daemon-reload</code> to load the new config.</p>

While this advice may be useful, the question doesn't ask anything about systemd or with changing systemd service files.

The error from the question could (and did in my case) arise because I did not use `daemon-reload` to load the new config. Since this solved my problem - which was the same as OPs -  I thought it would be a good thing to know.

interesting, but for sure not the default behavious. I am normally on OpenSuSE. I have self compiled and downloaded full clients. Please provide some more info: did you use bitcoin core from website? Self compiled? apt-get? Did you check download files (hash)? 
I think I have a fresh Ubuntu virtual machine, where I could try to install the one you where using...

similiar discussion here, as bitcoin15 is not yet released: https://bitcointalk.org/index.php?topic=2172765.0. You downloaded from https://github.com/bitcoin/bitcoin?

just downloaded from github, and couldn't compile, cause autoconf throws already some errors. And for sure ./configure as well. Damn, wanting to help, and now need help myself ...

To avoid others doing same error (RTFM correctly, not in a rush): autogen.sh, not autoconf !! Now it's compiling. Update to follow.

re-compiled on an Ubuntu system, fresh from github.com:
$ uname -a
Linux ubuntu-ae 4.10.0-19-generic

$ bitcoind -version
Bitcoin Core Daemon version v0.15.99.0-g96ac26e5662

$ bitcoind -testnet -printtoconsole -rpcuser=123456 -rpcpassword=123456

$ bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=123456 getaccountaddress "myaccount"
n2r1aQiA37LLgy4qWjuLHXqA9ZhtcX4KG6

$ bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=123456 getbalance
0.00000000

and with wrong password:
$ bitcoin-cli -testnet -rpcuser=123456 -rpcpassword=1234564 getbalance
error: incorrect rpcuser or rpcpassword (authorization failed)

so s.th. is wrong with the sources? Or with Ubuntu setup. What kernel do you have (uname -a) ?

In case you changed your /etc/systemd/system/bitcoind.service make sure you run
 sudo systemctl stop bitcoind
 sudo systemctl daemon-reload
 sudo systemctl start bitcoind

to apply the changes.
The error from the question could (and did in my case) arise because I did not use daemon-reload to load the new config.
