Freeradius - MySQL communication issue

I am having configuration issues on a CentOS server (recent install). Freeradius is installed and mostly working. I can do radtests and get accept-reject replies back. The problem is that Freeradius is not communicating with MySQL properly. Although credentials are set correctly in /usr/local/etc/raddb/[login to view URL] when running radtest I see 'rlm_sql_mysql: Mysql error 'Access denied for user 'radius'@'localhost' (using password: YES)' This should be a simple fix for someone more knowledgeable than myself. To screen out copy/paste proposals, please include the syntax of a radtest command in your proposal.
