There doesn't seem to be a problem with user ID. Here are the two commands you 
suggest, executed from the host:

> ls -lsan ~/kdepim-dev
total 8
4 drwxr-xr-x  2 1000 1000 4096 Nov  2 19:56 .
4 drwxr-xr-x 60 1000 1000 4096 Nov  2 19:56 ..

> docker exec -it kdepim-dev ls -lsan /home/neon/kdepim
total 8
4 drwxr-xr-x 2 1000 1000 4096 Nov  2 19:56 .
4 drwxr-xr-x 6 1000 1001 4096 Nov  3 00:34 ..
