firebird - 付与された権限を持つfirebirdユーザーはテーブルにアクセスできません

Question

jaybird 経由で Firebird ユーザー (PIPPO) を作成し、gsec "display" に従います。

GSEC> di
     user name                    uid   gid admin     full name
------------------------------------------------------------------------------------------------
SYSDBA                              0     0           Sql Server Administrator
PIPPO                               0     0           GesAll 1.0 User
GSEC>

Firebird DB でロール (GESALLDB_USER) を作成し、いくつかの権限を付与しました。

SQL> show grant;

/* Grant permissions for this database */
GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON ANELLI TO ROLE GESALLDB_USER

GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON COPPIE TO ROLE GESALLDB_USER

GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON COVE TO ROLE GESALLDB_USER
GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON DATI_CONFIGURAZIONE TO ROLE GESALLDB_USER
GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON DATI_COVE TO ROLE GESALLDB_USER
GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON DATI_SOGGETTI TO ROLE GESALLDB_USER
GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON DEPOSIZIONI TO ROLE GESALLDB_USER
GRANT GESALLDB_USER TO PIPPO
SQL>

このロールを jaybird を介して新しいユーザーに付与しました (前の最後の行):

問題は、クエリを実行しようとするたびに、次のメッセージが表示されることです。

SQL> select * from anelli;
Statement failed, SQLSTATE = 28000
no permission for read/select access to TABLE ANELLI
SQL>

新しく作成したユーザーに TABLE を直接付与すると、すべてが機能します。

SQL> grant all on anelli to pippo;
SQL> show grant;

/* Grant permissions for this database */
GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON ANELLI TO ROLE GESALLDB_USER

GRANT DELETE, INSERT, SELECT, UPDATE, REFERENCES ON ANELLI TO USER PIPPO

SQL> connect "C:\Users\teiluke\Documents\Ondulati\DB\prova\gesalldb.fdb" user "p
ippo" password "topolino";
Commit current transaction (y/n)?y

これについて何か助けはありますか？
