I'm having issues with one of our developers deploying reports to SSRS, they seem to be able to deploy datasets, however not reports themselves. As a temporary measure, we've granted all privileges e.g. Content Manager, Publisher etc. and also sysAdmin on SQL Server, yet they are not able to deploy reports. However, a developer with what appears to have the same permissions (sysAdmin and all privilleges in SSRS) can deploy without issue. The error message can be seen below:
"The permissions granted to user 'Domain\Username' are insufficient for performing this operation."
