◆ decoy_user()

ACL_USER* decoy_user ( const LEX_CSTRING username,
const LEX_CSTRING hostname,
MEM_ROOT mem,
struct rand_struct rand,
bool  is_initialized 
)

When authentication is attempted using an unknown username a dummy user account with no authentication capabilites is assigned to the connection.

When server is started with -skip-grant-tables, a dummy user account with authentication capabilities is assigned to the connection. Dummy user authenticates with the empty authentication string. This is done to decrease the cost of enumerating user accounts based on authentication protocol.

Parameters
[in]usernameA dummy user to be created.
[in]hostnameHost of the dummy user.
[in]memMemory in which the dummy ACL user will be created.
[in]randSeed value to generate random data
[in]is_initializedState of ACL caches
Return values
Adummy ACL USER

◆ deinit_rsa_keys()

◆ init_rsa_keys()
