UPPER CASE HOST NAME ANYMORE Description: It is not possible to drop users with host names with upper case letters in them. i.e DROP USER 'root'@'Tmp_Host_Name'; is failing with error. Analysis: Since the fix 11748570 we came up with lower case hostnames as standard. But in the current bug the hostname is created by mysql_install_db script is still having upper case hostnames. So, if we have the hostname with upper case letters like(Tmp_Host_Name) then we will have as it is stored in the mysql.user table. In this case if use "'DROP USER 'root'@'Tmp_Host_Name';" it gives error because we do compare with the lower case of hostname since the 11748570 fix. Fix: We need to convert the hostname to lower case before storing into the mysql.user table when we run the mysql_install_db script.
