Issue User deletion on remote database server

[decanet]

Hello,

I've the same problem on 4 Plesk Servers (Onyx) with 4 differents remote database servers.
The connection is OK and I can create databases/users without problem.

The problem is when I delete a database user in the Plesk Panel, it is deleted in the Plesk Panel, but not really in the remote database server. So when I try to recreate the same user, an error message is displayed because the username already exists.
I can delete the user without problem on PHPMyAdmin with the same login/pass used by Plesk.

Is it a known problem and is there a solution?

Thank you

Benjamin
