[Samba] Safe to disable oplocks?

[Andrew Martin]

Hello,

I am running a fileserver with Samba 3.6.3, which I believe defaults to "max protocol = NT1", therefore all of my Windows 7 clients will be connecting to it over SMB1. Currently oplocks are enabled on the shares, but due to permission problems, I'd like to disable them. Is it safe to simply add "oplocks = no" to an existing share with connected Windows 7 and CIFS clients? 

Thanks,

Andrew
