Permissions required for Publish from Jaspersoft Studio?

[drueter_1]

I am running JasperServer 5.5 Community Edition.

I can publish reports from Jaspersoft Studio if the specified user is a member of ROLE_ADMINISTRATOR.

I have created a new role ROLE_TESTPUBLISH and would like to enable users that are a member of this role to publish reports, but not be able to administer the server.

It seems that if a user is not a member of  ROLE_ADMINISTRATOR that Jaspersoft Studios cannot connect to JasperServer at all--even if the specified user has Read and Write rights to the desired library folder.

What rights are needed to connect to JasperServer from Jaspersoft Studio?  Is there a way to set up a user that can publish reports from Jaspersoft Studio, but that cannot administer the server?
