OCI-28186
cannot grant privilege_name to a proxy-only connect user
- privilege_name: The name of an administrative privilege.
Cause
An attempt was made to grant an administrative privilege like SYSDBA, SYSOPER, SYSASM, SYSBACKUP, SYSDG, SYSKM, or SYSRAC to a proxy-only connect user. Since proxy authentication using an administrative privilege is not supported, such grants are not allowed.
Action
Grant administrative privileges only to accounts that are not marked "proxy only connect".
