Call the ModifyServerProcedureUser method to modify the rights for an existing user to an existing server-side procedure on a database server. Use the ProcedureName parameter to specify the existing server-side procedure name and the AuthorizedUser parameter to specify the existing user. You may use a wildcard (*) for the AuthorizedUser parameter , such as specifying just '*' for all users or 'Accounting*' for all users whose user name begins with 'Accounting'.
This method is only valid when the engine is running as a database server and the EngineType is set to etServer.
