According to Mikes's suggestion, placing the code below into "<alfresco dir>/tomcat/shared/classes/alfresco/extension/templates/webscripts/org/alfresco/repository/site/sites.post.json.js" solves the problem:
function main()
{
//Code below is added to check if user has administrator permissions
if (person == null || !people.isAdmin(person))
{
status.setCode(status.STATUS_BAD_REQUEST, "Site creation is not allowed, your have to be an Administrator");
return;
}
// Get the details of the site
var shortName = json.get("shortName");
if (shortName == null || shortName.length == 0)
{
status.setCode(status.STATUS_BAD_REQUEST, "Short name missing when creating site");
return;
}
// See if the shortName is available
var site = siteService.getSite(shortName);
if (site != null)
{
status.setCode(status.STATUS_INTERNAL_SERVER_ERROR, "error.duplicateShortName");
return;
}
var sitePreset = json.get("sitePreset");
if (shortName == null || shortName.length == 0)
{
status.setCode(status.STATUS_BAD_REQUEST, "Site preset missing when creating site");
return;
}
var title = json.get("title");
var description = json.get("description");
var isPublic = json.getBoolean("isPublic");
// Create the site
var site = siteService.createSite(sitePreset, shortName, title, description, isPublic);
// Put the created site into the model
model.site = site;
}
main();
