[Samba] 3.4.6 to 3.5.2 difficulties

[Julien Savoie]

Did an upgrade from samba 3.4.6 to 3.5.2  Left the smb.conf completely
unchanged.  As background I'm using samba on gentoo amd64 with a ldapsam
backend on openldap.  Upgrade went well, I thought.  Users could login
and access their home directories.  Service reloaded without issue.

Here was the issue though, windows 2003 servers couldn't login users
into the domain.  These servers were joined as domain members.  Logs as
follows:

> The browser service was unable to retrieve a list of servers from the
> browser master \\LDAP on the network
> \Device\NetBT_Tcpip_{87C2EC8F-2437-40F6-A637-4B7B3A70F5D5}.
>  
>  Browser master: \\LDAP
>  Network: \Device\NetBT_Tcpip_{87C2EC8F-2437-40F6-A637-4B7B3A70F5D5}
and also as a result this:

> This computer was not able to set up a secure session with a domain
> controller in domain USAINTEANNE due to the following:
> The RPC server is unavailable.  
> This may lead to authentication problems. Make sure that this computer
> is connected to the network. If the problem persists, please contact

It's almost as if "browse list" had been defaulted to no.  Obviously
this was a production issue and i didn't have time to fully
investigate.  Anyone have any ideas?

The remedy was to downgrade in portage back to samba 3.4.6.  Everything
worked as before, no issues.  From my initial investigation of the
portage tree under gentoo it appears no customization has been applied
to 3.5.2 ebuild that wasn't in the 3.4.6 ebuild.  I'll include the
diffs, but nothing note worthy.
