I have a geodatabase version 10.2.1 in SQL Server 2008 R2. It has only two feature classes in it. I have a database role in that database called 'DBEditors'. If I look at the privileges for the feature classes using ArcCatalog, it says that DBEditors has Select, Insert, Update, and Delete privileges. I have a user who is a member of the DBEditors group in the SQL database - I see this in SQL Server Management Studio under Database Role Properties. However, the user says that the delete option for the feature classes is greyed out in her ArcCatalog.
The feature classes are not in any topology and they are not connected to any feature services. The owner is DBO and they are not registered as versioned (they were, but I unregistered them). No one else has any locks on them (according to Geodatabase Administration). I've looked in SQL Studio and I don't see any duplicate/orphaned records in GDB_ITEMS or SDE_table_registry with the same tablename.
What else can I do?
