Where are EV admin roles defined in the directory database

Hi,

I am trying to overcome the following error with the BE archiving option.

Access denied. User is not in a role that allows '(STO) Can Administer vault Stores and Partions'

This error appears in the EV event log when I attempt to create a vault store.

No vault stores have as yet been created.

Symantec tech note TECH182988 has been applied to no avail.

I have trawled through a "Real" EV directory database and can find no reference to the defnition of Roles.

The only reference to managing EV roles is through the VAC.

Does anyone know of a method of managing roles via registry / directory database?

Many Thanks
