View 5.1 with multi domain

Hi everyone ! Happy new year !

Last week, I have updated our View 4.6 server to 5.1.2

Everything seem to work except option "login as current user"

I have 2 domains

Users from first domain can connect "as current user" without trouble.

Users from second domain cannot connect "as current user", they got an error "Authentification fail. Unable to connect as current user"

But If a click "ok" and enter username/password and select second domain, I can connect without error.

In Windows event of the server I got :

BROKER_USER_AUTHFAILED_GENERAL

User SECONDDOMAIN\username failed to authenticate

Attributes:

Source=com.vmware.vdi.broker.filters.GssapiAuthFilter

Time=Mon Jan 07 10:18:42 EST 2013

Secerity=AUDIT_FAIL

Node = view.firstdomain.local

Module=Broker

UserDisplayName=SECONDDOMAIN\username

Acknowledged=true

Someone can help me ?

Thanks you
