// Description:

// DBMS security policy - testing new APIs.

// This test app has "NetworkServices" (SCHEMA) capability, which allows it to

// modify the DBMS structure but not to write any data in the tables.

// The UID policy file is 11335579.spd.

// Please, ensure that t_dbenvcreate test is executed before t_dbplatsec<N>/t_dbplatsecperf tests!

// Please, ensure that t_dbenvdestroy test is executed after t_dbplatsec<N>/t_dbplatsecperf tests!
