I can't believe I have to ask this question but here I am.
I have created a user APC in my Free Tier instance, connecting to Oracle Web SQL Developer as the ADMIN user:
<pre>
create user APC identified by VALID_string_123;
grant create session, create table to APC;
</pre>
This seems to work.
However, when I sign out of ADMIN and attempt to sign in as APC it fails with this message:
"An invalid user name or password was supplied. "
I presume I'm missing something obvious. Can somebody tell me what that is? And, yes, I am entering the correct password.
