Running nismap.exe with –y parameter creates a map with “.” instead of “_”

“nismap.exe” does not create the map name as expected when using the –y parameter. Below is an example of the attempt to use nismap.exe with –y to create the map named auto_home_svr_test:

 C:\temp>nismap.exe
create -i 1 -g " " -s localhost -f
"C:\Windows\IDMU\nis\nis2ad.log" -y auto_home_svr_test

Activity =
Creating map = 'auto.home_svr_test'...

SUCCESS

With further research, it was confirmed that this is a default behaviour of the nismap function.
