Interesting. I can reproduce exactly what you're seeing:
% sudo pw user add -n fred -u 1010 -m
% id -P fred
fred:*:1010:1010::0:0:User &:/home/fred:/bin/sh
% ls -lad /home/fred
drwxr-xr-x 2 fred fred 512 Mar 26 08:01 /home/fred/
% sudo pw user mod fred -u 1005
% id -P fred
fred:*:1005:1010::0:0:User &:/home/fred:/bin/sh
% ls -lad /home/fred
drwxr-xr-x 2 fred fred 512 Mar 26 08:01 /home/fred/
% id -P 1005
fred:*:1005:1010::0:0:User &:/home/fred:/bin/sh
% id -P 1010
fred:*:1010:1010::0:0:User &:/home/fred:/bin/sh
% sudo grep 1010 /etc/master.passwd
fred:*:1005:1010::0:0:User &:/home/fred:/bin/sh
However, running pwd_mkdb(8) seems to cure the problem very effectively:
% sudo pwd_mkdb /etc/master.passwd
% id -P fred
fred:*:1005:1010::0:0:User &:/home/fred:/bin/sh
% id -P 1005
fred:*:1005:1010::0:0:User &:/home/fred:/bin/sh
% id -P 1010
id: 1010: no such user
% ls -lad /home/fred
drwxr-xr-x 2 1010 fred 512 Mar 26 08:01 /home/fred/
Looks like a bug to me...
Cheers,
Matthew
