Need help on "net ads join" fails when we have "%" in the username - 2nd Try........

Hi Rowland,

Microsoft 2008 server allows you create username with % in it. I was working on bug to support special characters in domain name.

Thanks,
Lokesh

When I posted, I really didn't think it would work, but I have never been stupid enough to use something in a username that I know is a delimiter used by Samba and windows. If the OP is willing to take a bit of advice, I would advise him to stop using stupid things in usernames. :-)
