Answer 1

In the Domain Controller Security Policy on my active directory domain, I opened Local Policies -> Security Options and changed "Microsoft network client: Digitally sign communications (if server agrees)" to Enabled, and I changed "Microsoft network server: Digitally sign communications (if client agrees)" to Enabled. I then did GPUPDATE from a cmd prompt on the domain controller and I was able to bind with my 10.4.7 PowerBook.
But now that I am bound I still cannot authenticate with domain credentials. Yes, in SMB/CIFS I have set the workgroup to be the netbios name of my domain. And the clock is synced with the domain controllers. I have even edited my smb.conf file with the "realm = MY.DOMAIN" and "security = ADS" and "spnego = yes" lines (where, of course, "MY.DOMAIN" = my domain name). But when I get to the login screen and type in my AD username and password, I get the shaking screen. It's like it isn't even trying to authenticate me with the domain.
So if anyone else was in that situation and figured it out, please let me know. I am also going to post this as a new topic.
FYI, I think the recommendation to solve this issue by using dcpromo to demote a domain controller is terrifying, excessive, and erroneous... and seeing it with a yellow "Helpful" star next to it is pretty scary. I think the person who made that suggestion would have been successful wtih the registry changes if the "Domain Controller Security Policy" had been edited, instead of the "Domain Security Policy."
