To perform user management with gsec, the user must provide the extra switch -role rdb$admin.

In a regular database, the RDB$ADMIN role is granted and revoked with the usual syntax for granting and revoking roles:

GRANT [DEFAULT] RDB$ADMIN TO username

REVOKE [DEFAULT] RDB$ADMIN FROM username

Table 1. Parameters for `RDB$ADMIN` Role `GRANT` and `REVOKE`
Parameter	Description

To grant and revoke the RDB$ADMIN role, the grantor must be logged in as an administrator.
