I suppose using uid <1000 is the problem. Usually uids below 1000 are 
considered system uids. From /etc/adduser.conf:

# FIRST_SYSTEM_[GU]ID to LAST_SYSTEM_[GU]ID inclusive is the range for 
UIDs
# for dynamically allocated administrative and system accounts/groups.
# Please note that system software, such as the users allocated by the 
base-passwd
# package, may assume that UIDs less than 100 are unallocated.
FIRST_SYSTEM_UID=100
LAST_SYSTEM_UID=999

FIRST_SYSTEM_GID=100
LAST_SYSTEM_GID=999
