Revoking Permission from a User or a Role

After a permission has been granted on a table, it can be subsequently revoked by using the tibdg user revoke or tibdg role revoke command.

Prerequisites

Ensure that you have transport encryption in the grid by setting encrypted_connections=all in the grid configuration. See Enabling Transport Encryption on a Data Grid.

On a specific table, to revoke permissions from a user, use the tibdg user revoke command as shown in the following example:
```
tibdg user revoke user1 table1 READ
```
The other possible permissions are WRITE and ALL (read and write).
On a specific table, to revoke permissions from a role, use the tibdg role revoke command as shown in the following example:
```
tibdg role revoke role1 table1 READ
```
The other possible permissions are WRITE and ALL (read and write).
