Few days ago, after make an update, i noted that cant SMB don't load, i check the logs and find an extrange error.
The Active Directory Connector was not working, it was unable to find the PDC.
The snbd log says:

I check connectivity, the server see the PDC. At least whit ping
Another strange error is, try to reconnect whit the ADC but the form seens not to work, i put fake configs and always seens to accept it dont validate and dont writte to SMB config.
I have a ClearOs Professional but no clear care subscription.

    I finally go it.
    It was a DNS resolution problem, the WPAD app of clearos create a second alias like an this was not supported by SAMBA, i have SAMBA PDC.
    I didn't see this alias because was not listed in web admin, just checking by ssh /etc/hosts
    Once removed it goes all fine.
    Thanks to ClearOs support.
