Thanks Robert.
I've tried switching over to the AD back-end (which does sound like what I want), but I still receive only the errors:
failed to call wbcGetpwnam: WBC_ERR_DOMAIN_NOT_FOUND
I restarted both winbind and smbd after changing the config. Is there some cache I have to flush, or some other config that needs to be changed beyond the settings in smb.conf?
thanks again!

My updated smb.conf:
workgroup = CORP
security = ADS
#password server = 192.168.77.251
realm = CORP.MYCOMPANY.COM
allow trusted domains = yes
winbind use default domain = yes
winbind nested groups = YES
idmap config CORP : backend = ad
idmap config CORP : default = yes
idmap config CORP : schema_mode = rfc2307
idmap config CORP : range = 800 - 99999
