Something running on your ypserver is trying to match an entry in the 
passwd.adjunct map from the ypserver - which doesn't exist

I believe the passwd.adjunct file is used for shadow passwords (on 

I doubt it is a major issue as whatever is requesting this map is 
probably just seeing if it exists - and probably falling back to using 
the passwd.byname map.
