Certificate issue is taken care of.
100722 15:57:59 [ERROR] Slave I/O thread: error connecting to master 'firstname.lastname@example.org:3306': Error: 'Access denied for user 'slave_user'@'basestar.investmenttool.com' (using password: YES)' errno: 1045 retry-time: 60 retries: 86400
I have tried the following:
telnet mercury.investmenttool.com 3306
This works. Proves there is no firewall problem.
I tried logging on as this user from the command prompt
mysql -u email@example.com
Gave the correct password
Server is not logging the problem.
