How can I print the LdapLoginModule log?

My expectation is to see the logging while a user tries to logging.

like this
[LdapLoginModule] authentication-first mode; SSL disabled
[LdapLoginModule] user provider: ldap://*****
[LdapLoginModule] attempting to authenticate user: *****
[LdapLoginModule] searching for entry belonging to user: *****
[LdapLoginModule] found entry: CN=,OU=,OU=,OU=,DC=,DC=
[LdapLoginModule] authentication succeeded
[LdapLoginModule] added LdapPrincipal “CN=,OU=,OU=,OU=,DC=,DC=” to Subject
[LdapLoginModule] added UserPrincipal “*****” to Subject

however, I can not see any login in server.log.
then I tried to modify the logging level in standalone.xml
however whenever I restart the server the configuration is overwritten back to the version before.
why? anyone can help me?

Hello,

This component is not delivered by Bonita, but by Oracle. Source code is available:

http://www.javased.com/index.php?source_dir=openjdk-7%2Fcom%2Fsun%2Fsecurity%2Fauth%2Fmodule%2FLdapLoginModule.java

The source code shows the component do a System.out.println. Then the question is “how can we redirect the Tomcat output to the log file? “

According

https://serverfault.com/questions/252934/how-to-redirect-tomcat-console-log-to-files-tomcat-started-via-windows-bat

it should be possible by editing conf/logging.properties, and change the line

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

to

.handlers = 1catalina.org.apache.juli.FileHandler
