I found it... after i added debug code to ndomod_open_sink in ndomod.c to 
print out all variables used by ndo_sink_open. It turned out they were 
"(null)". All of them. 

And you might guess it now: it was an error in the path to the ndomod.cfg - 
file in nagios.cfg. 

Function "ndomod_process_config_file" should really give an appropiate 
warning, returning just NDO_ERROR isn`t sufficient. 

Patch:
 diff /root/ndoutils-1.4b4/src/ndomod.c  ndomod.c
