[Samba] Windows 7 login fails after server crash

[Gaiseric Vandal]

This morning due a a power outage our samba servers crashed.  All looked 
OK at reboot (at first) -  users  who had stayed logged in could still 
access shares.

However users who tried to log back into the network got the "The trust 
relationship between this workstation and the primary domain failed" 
message.  Removing a machine from domain and rejoining did not help.

Servers are a classic domain, samba 3.6.25 on Solaris 11 with Solaris 
patch idr2408 to install  BADLOCK fixes (in order to fix compatibility 
with  linux samba 4.x member servers and as well as to fix a trust issue 
with a Windows 2008 AD domain.)     I had applied this patch several 
weeks ago and restarted samba services but not restarted the server.   
    Removing the patch  from the domain controllers and primary file 
server seemed to fix the problem.


As part to patch, I also added  "server signing = No"  to smb.conf since 
the new default seemed to be to enable it.

Guessing some schannel thing ?


I didn't see anything definitive in any logs.


I may compile samba 4.4.x in case samba 3.x has some other compatibility 
issues I don't know about.

Appreciate any insight or suggestions.

Thanks
