When sending a login request, I send a message containing all the instructions, and I receive a message from the server containing the same information, except for the password. What is the problem?

I don’t know which FIX engine you’re using. From the log messages it looks like a QuickFIX variant.  
It seems in your DataDictionary you have marked tag 554 as required on the `Logon` message. But it shouldn’t be required on incoming messages (only incoming messages are validated against the dictionary), the counterparty will not echo back the password in 554.
