In graphical mode, in the authorizations properties of a sites collection, we can decide if users can request the access or not.
I'm wondering how to do this in powershell.
$spsite = Get-SPSite http://URL
I thought it was the way to do it, but no =/ And with my poor english, I don't find anything on google.
If it is more explicit with this :
1st, on the site collection, you do this http://i.msdn.microsoft.com/dynimg/IC630042.png
Then you click on site authorizations, and you got this (can't post image without reputation :s ) http://hpics.li/4fbd8be
I just want to uncheck this parameter, in powershell :)
