I am running DNN version 05.01.04 (3) and just installed the External Database Provider. After getting several errors, i found an error in the dbo_ICG_Auth_IsHostOrAdmin procedure. It is referencing the [Users] table instead of the [dbo_Users] table. I am assuming that the table names have recently been changed?

In any case, if you are upgrading to the latest version and encounter critical errors review the table names in the IsHostOrAdmin stored procedure. There are 3 tables names that need to be changed.

I hope this helps someone else going thru the same problems!
