I have a problem. When i create a NEW site with a MySQL database for example: webname: web1 database name: web1_db1 mysql username: web1_u1 When the new created user web1_u1 wants to access database web1_db1, this user can not access phpmyAdmin with the created password. All the existing MySQL users have normal access via phpMyAdmin so that's ok. Only when i create a new site with a new MySQL user, this user can not access phpMyAdmin. Recently, i had to update MySQL 4.0.24 to 4.1.11. I've done so using the command on my Debian server: apt-get install mysql-server-4.1 mysql-client-4.1 libmysqlclient14-dev Could this be the reason that new users can not access phpMyAdmin anymore? I think it is possible because i found out that MySQL 4.1 and up, uses an authentication protocol based on a password hashing algorithm that is incompatible with that used by older clients. I use phpMyAdmin 2.6.4-pl3 provided by ISPConfig. When i access phpMyAdmin as root i see that the encrypted password of the new created MySQL user is marked with a * in the beginning of the password field within the database. What does this mean? What could be the cause and is there a solution for my problem?
