That was the first mention of a crash, but it seems that the OP has been 
trying various idmap backends (and probably other things), so whilst 
Samba shouldn't crash, who knows if it isn't self inflicted. Yes, the 
crash should be investigated first.

What isn't helping is the sanitisation
We have been given DOMAIN/WORKGROUP 'AD'
The connecting user appears to be from the 'ADLOCAL' DOMAIN/WORKGROUP
The REALM is 'AD.UCHICAGO.EDU' but the log fragments show what appears 
to be the machines FQDN 'midway3-dm1.rcc.local'

Nothing matches.

[Samba] check_account: Failed to find local account with UID" issue / The university of Chicago

Thanks, it was perfectly working prior to rebooting the server. Any suggestion
to fix this issue would be appreciated. How to fix ?ADLOCAL\jlspellberg
ADLOCAL\domain? to username / group name only?
