Fw: user problem

[kennonward]

I have mysql installed on a linux platform.  I have no problem running every thing as 
root.  When  I try to run mysql as a user other than root, I entered command use 
mysql. I get error  1044:access denied for user:@localhost to database 'mysql'.

is there a file that I need to change the permissions on or change the group in a var 
or usr subdirectory.

Thank you for your help on this matter.
