consistent UIDs across multiple systems.

my user login on my ubuntu 14.10 system is "shino" and its uid is 1001.  
i recently acquired a synology 1815+ NAS and added users to the system.  
on the synology, the uid for "shino" is 1026, which is visible in the 
NAS's /etc/passwd.  the problem arises when mounting CIFS on a PC 
(win8.1) using the login "shino"; files it creates are UID 1026 and it 
can't read/write existing directories created with UID 1001.

I'm looking for recommendations for the best way to maintain a uniform 
name/uid mapping across systems (including the NAS).  i don't mind 
manually changing multiple systems, there are a small number of users 
(basically my family) and that's not likely to change anytime soon.
