[Koha-devel] Security question about db user login

[Philippe Blouin]

Is there a way to disable the dbuser's ability to login?  Since changing 
the db password is usually fraught with unexpected results, I'd like to 
be able to just block this access.  I figured maybe a preference already 
exists for that but couldn't find it.
Any Koha issue that might arise from doing that?  (beside the database 
upgrade, which I never want the users to face anyway).

Thanks
