Report Builder button missing - exec rep defs ticked & rep build ticked

I can see report builder in IE (I am report admin), but my users are not able to, despite having ticked 'report builder' against their name in folder security.

They have
Browser, Report Builder

Why can't they see it?

"Site Settings - Security - Config sys wide role defs - sys user " has "execute report defs" ticked.

Anyone, hmm?

They also need to be listed as System Users under Site Settings. In Report Manager (IE) click on Site Settings / Configure Site-Wide Security / Add a new role assignment with the userid and grant them System User status. Have the user refresh IE and they should see the Report Builder icon.

|||Confused....

We currently use AD groups to control user access to the RS.

An AD group is assigned one or more roles. e.g. 'browser','content manager'

How is it they are able to access the RS if they are not part of 'system user'?|||the solution:

create an AD group called report builder - add all your users who require RB access to this in IE, report manager: site settings - site wide security - new role assignment - enter ADReportBuilderGroupname and tick "system user"
