I need to allow a consultant to connect to SSIS on a SQL Server 2008 box without making him a local administrator. If I add him to the local administrators group, he can connect to SSIS just fine, but it seems that I can't grant him enough permissions through SQL Server to give him these rights without being a local admin.

I've added him to every role on the server, every database role in MSDB shy of DBO, and he's still not able to connect. I don't see any SSIS-related Windows groups on the server - Is membership in the Local Administrators group really required to connect to the SSIS instance on a SQL Server? It seems like there is somewhere I should be able to grant "SSIS Admin" rights to a user (even if it's a Windows account and not a SQL account), but I can't find that place.

UPDATE: I've found an MSDN article (See the section titled "Eliminating the 'Access if Denied' Error") that describes how to resolve problem, but even after following the stepsI'm still not able to connect. Just wanted to add it to the discussion
