[Samba] Problems authenticating after upgrade to sernet-samba 4.3.9-24

Hello list,

Just did a major Samba/CTDB upgrade and our previously working auth setup is having some issues under the new version.  Would appreciate some help troubleshooting.  It seems like we are close, since the trust relationship between our Samba servers and the AD service looks OK.  But winbind fails like this:

[root at mako-nsd4 ~]# wbinfo -n jsmith
failed to call wbcLookupName: WBC_ERR_DOMAIN_NOT_FOUND
Could not lookup name jsmith

However, this all seems OK to my (inexperienced) eye:

[root at mako-nsd4 samba]# wbinfo -t
checking the trust secret for domain MYEDU via RPC calls succeeded

[root at mako-nsd4 samba]# net ads testjoin
Join is OK

[root at mako-nsd4 samba]# net ads info
