I think problem is here. That's really strange, you have to use the 
password without quotes.

Can you please try to set:
pool.default.auth.simple.bindDN = 
cn=authenticate,ou=System,dc=example,dc=org
pool.default.auth.simple.password = XXXXXX

just without the variables. if the DN is not empty now.
