NtlmLogonException StackTrace is printed in logs each time an user (that not exist or password is not correct) try to login. 

Logs become bigger and performance could be affected for those traces that do not contribute so much useful information. Authentication without NTLM do not print a StackTrace each time login failed by user do not exist or password is not correct.

Steps to reproduce:

1. Start a portal with NTLM authentication. (https://dev.liferay.com/discover/deployment/-/knowledge_base/7-0/ntlm-single-sign-on-authentication)
2. Try to login with an user that does not exist.

 Expected behavior:
Print a warn message in log with useful information. 
 Current behavior:
Print Full StackTrace with some information that it is not really useful.
