Use this -
contentRepository.Save(newUser, SaveAction.Publish, AccessLevel.NoAccess););
I figured the issue, Save just worked fine after assigning a value to newUser.Name property. So it was not any access rights issue but Name is like a mandatory property to save a content. It is bit silly I didn't realise it, but the access denied error just freaked me at first place. Thanks
We use federated authentication and for each user we create a User item (extended from ContentBase).
In the SecurityTokenValidated context, if the User item is not available, we need to create new User item.
How can we save the new User content in the OWIN SecurityTokenValidated context?
