I changed my smb.conf to include server signing = no and all my problems 
immediately went away. Hooray!

Interestingly, the problems I've been seeing also appeared piecemeal 
over the past month or so, which made it the more baffling to debug. 
First I couldn't change permissions using domain ACLs, then I couldn't 
browse the server, then (recently) client systems started refusing to 
log domain users on.  My best guess would be that there are some fairly 
long timeouts or caches that kept things working until they expired.
