Wrong MySQL credencials settings after ISPConfig 3 update

[vaio1]

Hi guys,

I have found a problem in ISPConfig after the update.
I have 3 servers:

webserver.mydomain.com
dbserver.mydomain.com
mailserver.mydomain.com

Follow my steps:

1. Create a user
2. Create a database user
3. Create a database
4. Check the mysql user table in dbserver
5. Try to connect from the webserver to dbserver

You will see that the webserver.mydomain.com is not included in the mysql database credencials in the dbserver blocking the requests and generating a wrong connection to the database.

I can see just:

localhost    dbuser
123.123.123.123  dbuser

How have I to solve this issue?
Is there a way to add a trusted server in the mysql for all the database users?

thanks
