ACTUAL BEHAVIOR
---------------
ORA-01917: user or role 'X' does not exist

Created a schema to install a system but everything I try to do I get the ORA-01917 message: user or role 'X' does not exist, but the schema exists, I can view it but I can't do anything. I am asking the Support assistance to identify the issue.

SQL> select username from dba_users where username='test_user';

USERNAME
------------------------------
test_user <<<<<<<<<<<<<<<<<<<<< User exist in the database

SQL> select * from test_user.table1;
select * from test_user.tableq
*
ERROR at line1:
ORA-00942: table or view does not exist

SQL> grant create session to test_user; <<<<<<<< But hitting ORA-1917, user test_user does not exist
grant create session to test_user
*
ERROR at line 1:
ORA-01917: user or role 'TEST_USER' does not exist

SQL> drop user test_user cascade; <<<<<<<<<<<<<< While dropping this user, again Oracle says user does not exist
drop user test_user cascade
*
ERROR at line 1:
ORA-01918: user 'TEST_USER' does not exist
