Kolab on Centos 7 roundcube not log in

[Gelpi Andrea]

Hi,
	I have just installed kolab 3.4 on Centos 7.

I follow various docs from docs.kolab.org to configure the system also 
for multi domain (not alias domain).

I can connect to kolab-webadmin where I added a test user.

When I try to connect to rouncube I got a login failure.
I check many logs but all I can find is:

Aug 19 00:27:00 mail imaps[20939]: starttls: TLSv1.2 with cipher 
ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits new) no authentication
Aug 19 00:27:00 mail ptloader[19677]: LDAP search for domain failed.
Aug 19 00:27:00 mail imaps[20939]: ptload(): bad response from ptloader 
server: identifier not found
Aug 19 00:27:00 mail imaps[20939]: ptload completely failed: unable to 
canonify identifier: test.test2 a treos.it
Aug 19 00:27:00 mail imaps[20939]: SASL bad userid authenticated
Aug 19 00:27:00 mail imaps[20939]: badlogin: localhost [::1] PLAIN 
[SASL(-13): authentication failure: bad userid authenticated]

I check and verify all services are running.

I have a kolab 3.2 on debian 7 working.

I check configuration file more than once, but I can't find any error.

I tested imap connection and seems to work.
Kolab lm give me user/test.test2 a treos.it

Where can I look to analyze and solve the problem?

Thank You
