I was using 1.2.78 but upgrade to 1.2.79 made no difference...

However - I just tried to log in to phpMyadmin using the user being created during the slave creation, but failed! Then I logged in as root, and noticed something I had not noticed earlier.

It turns out that the user being created during slave dreation, gets the servers public ip set in the hostfield. So I just tried to change this to "localhost" instead - and voila, then I could log in and create tables etc. in the database.

So - is there any place I could change this, so that the hostfield on the user is set to "localhost" instead of the servers public ip? I think this might solve my problem!

For what its worth, I have now tested slave creation from frontend, but get the exact same result.

500 - JDatabase::getInstance: Could not connect to database
joomla.library:2 - Kunne ikke forbinde til MySQL. (Could not connect to MySQL)

You can force the value to use concerning the MySQL host when you edit configure the "multisites.cfg.php" file.
There you can force the "host" value to "localhost".

Touchdown - this did the trick for me!

Thank you very much for your help!
