[Koha] corrections to previous message with apologies

Using Koha 3.0.0 on Linux. We had trouble with a failed file - you sent us some advice to use gedit, and we recovered this file. Unfortunately, another problem has arisen - cannot log into "kohadbuser" because of too many authentication failures - the exact message reads "Access denied for 127.0.0.1. The host has been blocked because of too many authentication failures." Also cannot log into kohaadmin. "" WE CAN LOG INTO KOHADMIN. Apologies for this wrong information - Caramel"" The question is how can we retrieve the passwords? At the same time we can't log into the local hosts. I hope this is not too many problems for you to solve... Thanks heaps Carmel Young Catholic University Malawi
