Hmm, EINPROGRESS is not called out specifically in the man page:
"ERRORS
0 or ENOENT or ESRCH or EBADF or EPERM or ...
The given name or uid was not found."
Do you have any other nsswitch.conf settings besides the flat files for
/etc/passwd and friends? Is nscd running?
Did you uninstall the Ubuntu version of NUT before building from scratch? If
not, you might need to run strace to find out why getpwnam() is not returning a
user structure.
