Hi all,
how can I determine if current user is site collection administrator in any site collection using REST or CSOM in Javascript? This should be done from a Azure Web App.
The user logs on to the Web App. And then a check have to de done to see if the user is a site collection administrator in at least one of the existing site collections. If the check fails, the user should be logged off with a note.
To ensure that performance does not decrease, this check should be carried out with a single call.
Any suggestions?
Regards,
Ralf
