 Unix Tip #4532- August  8, 2025
 
BE CAREFUL WITH NIS+  
  
To rebuild your /etc/passwd file use:  
nisaddent -rv -f /etc/passwd passwd  
  
HOWEVER, if you perform the above command  
you must perform the following command on  
the shadow file:  
nisaddent -mv -f /etc/shadow shadow  
  
DO NOT USE the nisaddent -rv -f command on  
the /etc/shadow file, this command will confuse  
replica servers and lock everyone off of a system.
