Problems with login in to ODK-X Server web-ui. Incorrect username or password

Hi, I have the same problem…

I have installed ODK 2.0 Server on a VirtualBox running Ubuntu Server 18.04. I have access in php LDAP admin from host machine. I have created a user as decripted at ODK-X Sync Endpoint — ODK-X Docs

But, I cannot login in web-ui …

Is there any specific configuration that I miss?
(I have test all the above.)

Thanks!
