I log into portal using spadmin account, then go to a doc lib "TestDocLib". I can see the values for all the metadata fields (about 8 metadata fields) and I can click on Edit to open the editform.aspx (and perform modification if needed).
I added user in a spgroup with contribute access. The user jsmith logs in, go to TestDocLib, the entity column in the view shows up but values are nulled or empty and he gets 403b error when clicking on the edit button. (however, view properties and then edit item lets him modify the data).
What is happening?
