So to conclude, Debian's useradd tried to run userauth via NIS by default,
which will make rpc calls/connections. 

Portmap is a server that converts RPC program numbers into DARPA protocol
port numbers.  It must be running in order to make RPC calls.

grml doesn't runs portmapper, and I never need to make RPC calls. 

- is it ok to remove the Portmap from my system?
- is there any way to disable Debian's useradd from using NIS and making
rpc calls/connections?

slocate portmap/passwd
slocate nfs/portmap

both above return nothing. 

slocate portmap returns only the following files:
