Search Bonita Portal Users returns "no data"


I'm trying to search users in Admin Page on Bonita Portal 6.5.4 on Centos 6x, and Bonita Engine returns no data. I can't change passwords or disable users!

The bonita.log returns:


2019-02-05 14:43:57 org.bonitasoft.console.common.server.login.datastore.LoginDatastore
SEVERE: Error while logging in the engine API.

Can someone help me, please!

Thanks in advance,
