Sometimes this error is get because of Oracle 11g credentials are case sensitive.
Try to set SEC_CASE_SENSITIVE_LOGON false again, then and alter password again as follows..

Sometimes this error is get bacause of Incorrect $ORACLE_SID, so check your $ORACLE_SID parameter. If your $ORACLE_SID is set to the wrong system ID then you may get a ORA-01017 error because you are connecting to the wrong instance.
The credentials provided when connecting remotely as sysdba are compared to the contents of the passwordfile.
Password file authentication is enabled by setting the database parameter remote_login_password file to “shared” or “exclusive”.
SQL> alter system set remote_login_passwordfile=exclusive scope=spfile;
