[Samba] wbinfo -r 'username' displays inconsistent results across DC's

[lingpanda101]

Hello,

     Looking up a users group membership I'm showing different results 
on each DC. UID and GID mapping appears consistent but not all group 
membership is displayed. I've verified idmap.ldb is backup up and copied 
over to the other DC's. I do notice when taking a hot backup of 
idmap.ldb, the file size is dramatically smaller than the original. 
Using Microsoft RSAT to view group membership displays consistent 
results. This behavior is not consistent for all users. Many show 
consistent results while others do not. DC1 which is the first 
provisioned DC appears to display all group membership accurately with 
wbinfo -r.

Ubuntu 14.04LTS

Samba 4.7.5
