Ldap cmdbuild 3.3.2 ready2use

Hi, i’m trying to enable ldap on the last version of cmdbuild ready2use but i’m having some trouble.
I don’t understand where to insert the auth.conf file. I’ve tried in:
/var/lib/tomcat9/webapps/cmdbuild/WEB-INF/conf
and in :
/var/lib/tomcat9/conf/cmdbuild/
but when i execute :
sh cmdbuild.sh restws setconfig org.cmdbuild.auth.ldap.server.port 389
it throws me this error:

18:17:03.716 ERROR o.c.u.cli.commands.RestCommandRunner - error building file password

this is my auth.conf file :
org.cmdbuild.auth.methods=LdapAuthenticator,DBAuthenticator
org.cmdbuild.auth.ldap.server.address=ldap.server.net
org.cmdbuild.auth.ldap.server.port=389
org.cmdbuild.auth.ldap.use.ssl=false
