Initialize this security context from the passed in credentials
and activate it in the current thread.
@param[out] backup Save a pointer to the current security context
in the thread. In case of success it points to the
saved old context, otherwise it points to NULL.
During execution of a statement, multiple security contexts may
be needed:
- the security context of the authenticated user, used as the
default security context for all top-level statements
- in case of a view or a stored program, possibly the security
context of the definer of the routine, if the object is
defined with SQL SECURITY DEFINER option.
The currently "active" security context is parameterized in THD
member security_ctx. By default, after a connection is
established, this member points at the "main" security context
- the credentials of the authenticated user.
Later, if we would like to execute some sub-statement or a part
of a statement under credentials of a different user, e.g.
definer of a procedure, we authenticate this user in a local
instance of Security_context by means of this method (and
ultimately by means of acl_getroot_no_password), and make the
local instance active in the thread by re-setting
thd->security_ctx pointer.
Note, that the life cycle and memory management of the "main" and
temporary security contexts are different.
For the main security context, the memory for user/host/ip is
allocated on system heap, and the THD class frees this memory in
its destructor. The only case when contents of the main security
context may change during its life time is when someone issued
CHANGE USER command.
Memory management of a "temporary" security context is
responsibility of the module that creates it.
@retval TRUE there is no user with the given credentials. The erro
is reported in the thread.
@retval FALSE success
