MySQL query (over SSL) fails in IIS 7 using default AppPool identity

Question

I am trying to run a website locally in Windows 7 under IIS 7. I have the AppPool configured to use "Classic" mode, but connecting to a MySQL DB that requires SSL fails. If I change the identity to my user account it works perfectly. It fails when using the default "ApplicationPoolIdentity" account. Is there something I'm missing somewhere? Why would running a MySQL query over SSL fail for certain user accounts?

Update: This is the exception that the MySQL Connector is throwing:
"Reading from the stream has failed. Attempted to read past the end of the stream."

Answer 1

Can you isolate the issue a bit further? Did you try accessing MySQL DB without SSL? Also, one point to remember here is ApplicationPoolIdentity is not a normal User account, it's a build-in security account with least security privileges.
