How to load Chinese Character in Mainframe(Zos) by using mload? - response (3) by Ivyuan

Hi,
Here is the explanation of mainframe CLI0543:
CLI0543 External security reported a security violation
Explanation: The logon request was rejected by the TDP SECLOGON feature.
Notes: This error is generated by TDP, reflecting either a rejection by an external security capability, or an error occurred
preparing the request for external security.
Remedy: Check the TDP job log for additional information ensure that the MSGS option of the SECLOGON command is
enabled. If an authorization failure occurred, ask your security administrator to review the access rules for the resource
which corresponds to the user- name you were attempting to logon with.
Good luck!
