Hello All,
Perhaps I'm missing something basic here but I can register clients to our Windows Server 2008R2 ADS domain via:

net ads join -U someuser

enter password for someuser

But I cannot join a RHEL 6 client via:

net ads join -U someuser%password

...which is documented in the man page for net.

I need to be able to automate joins in our build process which means I need to be able to make the net command take the username and password as a single argument which is detailed in the man page as a feature.

Here is the debug output I see when I try to do this:

Any ideas?
