Is it okay to modify the SQL Server Reporting Services' web.config file?

I need to implement custom security for SQL Server Reporting Services. To do this, I would like to add some configuration into the web.config of the SSRS' Reports Server web application.

My question is - is it safe to do this? Might my custom configuration be overrun by some SSRS process? Or by an automatic update开发者_JAVA百科 to the SSRS?

Yes.

MSDN gives examples of when to change stuff

As for updates, we've patched our installations with the same setting (and some others) and they didn't break. Given the number of potential legitimate changes to RS config files, I'd say a patch should not break it.
